The rotor 2 has a cylindrical shape or a cylindrical shape. The rotor core 3 and a plurality of permanent magnets 4 attached to the outer circumferential surface of the rotor core 3 at a predetermined pitch in the circumferential direction. Here, the number of the permanent magnets 4, that is, the number of field poles of the rotor 2 (pole) The number of the permanent magnets 4 is a ferrite magnet, a titanium magnet, a samarium-cobalt magnet, etc. The stator 5 includes a stator core 6A coaxially disposed on the rotor 2 so as to surround the rotor 2, and The stator winding 12 is wound around the stator core 6A. As shown in Figs. 2 to 4, the stator core 6A is provided with an annular yoke 7, and the inner peripheral surface of the yoke 7 is mutually circumferentially a plurality of teeth 8 protruding from the space (D). Here, the number of teeth 8 is 12. In addition, a plurality of 6 323142 201223081 teeth 8 are connected by the ends, and the axial direction of the yoke 7 One end is connected to the other end. Each tooth 8 has a predetermined direction in the circumferential direction of the yoke 7. The width (the third portion and the fourth portion) is the tooth base portion 8a protruding from the inner peripheral surface of the yoke 7, and the both sides in the width direction of the tip end portion of the tooth base portion 8a are roughly toward the circumferential direction of the yoke 7. The groove 16 is protruded from the tooth flange portion and 8c. The groove 10 is then formed by the space partitioned by the adjacent teeth 8 and the yoke 7. In more detail, the groove 10 By the adjacent tooth bases 8a, the tooth flange portions 8b and 8c extending from the tooth base portion 8a in the direction opposite to each other, and the portion of the yoke 7 located between the adjacent tooth base portions 8a are separated by At this time, the groove opening 1〇a is inclined at a predetermined angle with respect to the axial direction of the yoke 7, and the amount of protrusion of the tooth flange portions 8b and 8c from the tooth base portion 8a is followed by magnetic One end of the yoke 7 in the axial direction gradually changes toward the other end. Further, the groove opening 10a extends from one end to the other end in the axial direction of the yoke 7 (the axial direction of the core 7A), and the angle in the axial direction of the yoke 7 is the same angle. Then, in the cross section perpendicular to the axial direction of the yoke 7, the tooth flange portions 8b, 8c are as shown in Figs. 3 and 4, and are width-dependent (part S of Fig. 3, Fig. 4). The joint portion such as the base portion is formed to be narrowed toward the front end. Further, the tooth flange portions 8b and 8c have the same width (M) from the connection portion to the tooth base portion 8a to the vicinity of the front end portion, and the front end of the tooth flange portion rib and the & The portion from the side of the magnetic light 7 (outer peripheral side) faces the __ portion, and the amount of protrusion from the portion of the recording portion becomes large. 323142 7 201223081 Thereby, the adjacent tooth flange portion 8b and the circumferential side interval Lb are large. As shown in Fig. 2, the stator core 6A having the above-described shape of the outer peripheral side of the 8c is a laminated body in the thickness direction of the complex (four) ring-shaped secret member of the group. Each of the individual bodies is composed of twelve divided teeth 17 which are formed by a flat ring-shaped magnetic surface and which are protruded from the inner peripheral surface of the yoke structure 16 with a space therebetween. Each of the 叩 split teeth 17 has a split tooth base portion 17a which is formed by the inner peripheral surface of the magnetic vehicle constituting body 16 and a split tooth bulge which protrudes in the circumferential direction of the magnetic damper body 16 at both sides of the front end of the split tooth base portion 17a. Edges nb and 17C. Further, the cross-sectional shape of the annular magnetic member 15 perpendicular to the thickness direction naturally corresponds to the cross-sectional shape of the stator core 6A. Further, the end surface of the split tooth base portion 17a (four) and the inner peripheral surface of the split tooth flange portions ❿, 17c (the surface opposite to the magnetic vehicle constituent body 16) are located on the same curved surface having a radius of curvature slightly larger than the radius of the rotor core 3. on. Then, the distance from the axial center of the magnetic yoke structure 16 to the distal end surface of the sub-part base portion 17a and the inner peripheral surface of the split-tooth flange portions 17b and 17M is set to be longer than the axial center of the rotor core 3 The distance from the outer peripheral surface of the magnet 4 is long. Further, the protruding length of the divided tooth flange portions 17b and 17c from the divided tooth base portion 1a is different for each of the annular magnetic members 15. At this time, the protruding length of the split tooth flange portions 17b and 17c from the split tooth base portion 17a is set to gradually increase or decrease by the same length in accordance with the order of the laminated annular magnetic members 15. 323142 8 201223081 Then, the yoke structure 16 of the laminated plurality of annular magnetic members 15 and the division it 17 are formed by coaxially laminating the plurality of annular magnetic members 5 as described above, and the magnetic tube 7 and the teeth 8' are formed. The stator core 6A whose groove opening 1 〇 a is inclined with respect to the lamination direction of the annular magnetic member 15 (in other words, the axial direction of the yoke 7) is obtained. Further, the stator windings 12 are only provided in the same number as the teeth 8, and are wound around the tooth bases of the respective teeth 8, respectively. That is, the stator winding 12 is disposed on the teeth 8 in a concentrated winding manner. Then, the stator 5 is slid in the rotor 2 coaxially and rotatably around the rotor 2, and the dent base portion 8a and the tooth flange portion 8 of the permanent magnet 4 are obtained. An electric motor 1A having a predetermined air gap is formed therebetween. Further, by causing a current to flow to the stator winding 12, the permanent magnets 4 adjacent to each other in the circumferential direction are magnetized in opposite polarities with each other, and the torque of the rotor 2 can be controlled by the motor control of the stator winding 12. The size of the expectation. According to the electric motor 1A of the first embodiment, the tooth core of the stator core 6A. The width of Mb and 8c is such that the connecting portion of the tooth base portion ga and the tooth flange portion and gc is narrowed toward the front end of the tooth flange portions 8b and 8c. Therefore, the base end portions of the tooth flange portions 8b and 8c can be thickened to reduce the magnetic saturation, and the tip end portions of the tooth flange portions 8b and 8c can be reduced to reduce the magnetic flux leakage. That is, the motor 1A can simultaneously achieve reduction in cogging torque and torque chopping and increase in torque. In the first embodiment, the groove opening 1〇a has the same angle with respect to the angle of the magnetic direction of the magnetic vehicle 7 from one end to the other end in the axial direction of the magnetic wheel 7. The way the skewed opening is explained. However, the manner in which the groove opening π 1Qa is skewed with respect to the axial direction of the magnetic wheel 7 is not limited to this. For example, the end of the axis direction is oriented toward the other - the slot opening.

The form of the glyph is formed, and the triangle is wavy or sinusoidal.

The groove opening l〇a is deflected with respect to the axial direction of the yoke 7. That is, the groove birch P 2 L g opening Q 10a can also be deflected so that the yoke 7 angle changes from the one end in the axial direction toward the other end in the axial direction of the magnetic roller 7. The groove openings l〇a ^ , , , * ua are formed into a zigzag shape. For example, because the manufacturing angle, the difference, and the like of the rotor 2 are in the axial direction of the magnetic core 7, even if the thrust in either direction of the axial direction is generated, Reduce the thrust. (Second Embodiment) Fig. 5 is an enlarged view of an essential part of a stator constituting a motor according to a second embodiment of the present invention. In the fifth embodiment, the same or equivalent components as those in the first embodiment are denoted by the same reference numerals, and their description is omitted. In Fig. 5, the teeth 8 constituting the stator core 6A of the motor 1 are provided with tooth flange portions 8d and 8e instead of the tooth flange portions 8b and 8c. The tooth flange portions 8d and 8e are formed in the same manner as the tooth flange portions 8b and 8c except that the portion on the proximal end side thereof is gradually widened toward the width of the joint portion of the tooth base portion 8a. In other words, in the motor 1A, the tooth flange portions 8b and 8c are formed to have the same width from the connection portion (base end portion) to the tooth base portion 8a to the vicinity of the front end, but in the motor 1B, the tooth flange portions 8d, 8e The base end portion side is wider than the intermediate portion of the tooth flange portions 8d, 8e. The configuration of the motor 1B is the same as that of the first embodiment described above. According to the electric motor 1B of the second embodiment, the width of the tooth flange portions 8d and 8e is the direction of the connection portion between the tooth base portion 8a and the tooth flange portion 8b, 10 323142 201223081 8c toward the tooth flange portion 8b, similarly to the motor 1A. The front end of 8c is narrowed. Therefore, the motor 1B manufactured using the stator core 6B can simultaneously achieve reduction in cogging torque and torque ripple and increase in torque as in the case of the motor 1B. In the electric motor 1B, the proximal end sides of the tooth flange portions 8d and 8e are formed such that the width thereof gradually increases toward the connection portion with the tooth base portion 8a. As a result, the cogging torque can be further reduced. Next, the results of measuring the cogging torque of the motor ΙΑ, 1B and the analysis results thereof will be described. Fig. 6 is a graph showing the results of measuring the relationship between the cogging torque of the motor of the first and second embodiments of the present invention and the rotation angle of the rotor. Fig. 7 is a view showing the analysis result of the cogging torque measured by the electric motor according to the first and second embodiments of the present invention, and is a component showing the cogging torque due to the operational error of the rotor. The component of the cogging torque caused by the number of poles and the number of grooves, and the maximum amplitude of the cogging torque. In Fig. 6, the horizontal axis represents the rotation angle of the rotor 2, and the vertical axis represents the cogging torque. Further, the magnitude of the cogging torque is expressed by a specification value which is normalized by setting the maximum value of the cogging torque at the time of the second rotation of the rotor 2 to 1. Here, the number of the grooves 10 of the stator cores 6A, 6B of the motor ΙΑ, 1B is twelve. In this case, a part of the rotor 2 may be skewed to a desired shape. When the rotor 2 is rotated in one direction, the rotation angle of the rotor 2 is 30° at intervals of the arrangement of the grooves 10. 11 323142 201223081 The composition of the cogging torque of the periodic amplitude. Further, the number of poles of the rotor 2 of the motor ΙΑ and 1B is ten. It is known that in the case where the rotor 2 is rotated, a component of the cogging torque of 60 times of the reverberation of only the number of the grooves 10 and the least common multiple of the number of poles 10 of the rotor 2 is generated. That is, in the case where the rotor 2 is rotated in one direction, a component of the cogging torque having a cycle amplitude of 6° with respect to the rotation angle of the rotor 2 is generated. The waveform shown in Fig. 6 is analyzed, and the rotation angle of the rotor 2 can be derived from the cogging torque component of 30° and the cogging torque component of 6°. At this time, the rotation angle β 30° of the rotor 2 is the magnitude of the cogging torque component of the periodic amplitude, which corresponds to the cogging caused by the operational error of the rotor 2 (distortion or deviation from the desired size). The magnitude of the effect torque component, the magnitude of the cogging torque component having a periodic amplitude of 6 °, corresponds to the magnitude of the cogging torque component that varies due to the number of poles and the number of grooves. Next, Fig. 7 shows the magnitude of the cogging torque component due to the operational error of the rotor 2 and the magnitude of the cogging torque component which varies due to the number of poles and the number of grooves, in relation to the motor ΙΑ, 1 、, And the magnitude of the amplitude (Peak_Peak value) when the rotor 2 is rotated once. In Fig. 7, it is found that the components of the cogging torque caused by the operational error of the rotor 2 in the prepared motor ΙΑ and 1B become the main components of the amplitude of the measured cogging torque. Then, the motor 1B is a component which greatly reduces the cogging torque due to the operational error of the rotor 2 as compared with the motor 1A. Therefore, 12 323142 201223081 significantly reduces the cogging effect observed when the rotor 2 is rotated twice. The magnitude of the amplitude of the torque. The above results were examined. In the electric motor 1B, the base end portions of the tooth flange portions 8d and 8e are formed such that the width thereof is widened toward the joint portion of the tooth base portion 8a. Here, the connection portion between the tooth base portion 8a and the tooth flange portions 8d and 8e is a portion where the magnetic saturation is most likely to occur in the tooth 8. That is, in such a portion, the degree of magnetic saturation is sensitively changed by the operational error of the rotor 2 or the deviation of the residual density of the magnet, and the cogging torque or the torque chopping is apt to occur. It is determined that the stator core 6B of the motor 1B is formed such that the base end side of the tooth flange portions 8d and 8e is widened toward the joint portion with the tooth base portion 8a, so magnetic saturation is less likely to occur, and the operation error of the rotor 2 is caused. The resulting component of the cogging torque is significantly reduced. As described above, the electric motor 1B of the second embodiment can obtain an effect of reducing the cogging torque more than the electric motor 1A. (Embodiment 3) FIG. 8 is an enlarged cross-sectional view showing an important part of a stator of a motor according to a third embodiment of the present invention, and is a cross section showing a portion of the stator located in the vicinity of one end side in the axial direction of the yoke. In the eighth embodiment, the same reference numerals will be given to the same or corresponding parts as those in the first embodiment, and the description thereof will be omitted, and the illustration of the stator winding will be omitted for convenience of explanation. In Fig. 8, the motor 1C is provided with a rotor core 6C instead of the rotor core 6A, and the other configuration is the same as that of the motor 1A. 13 323142 201223081 The axial direction of the yoke 7 is formed such that the groove opening 10a enters the tooth base portion 8a on the one end side. The entry of the groove opening 10a into the tooth base 8a means the following. That is, the opening of the groove is formed such that the width of the front end side of the tooth base portion 8a is narrower than the width of the base end side of the tooth base portion 8a. Further, the other end side of the yoke 7 in the axial direction is formed so that the groove opening 10a enters the tooth base portion in the circumferential direction with respect to the tooth base portion 8a formed so as to enter the groove opening 10a at one end side. Within 8a (not shown). That is, at one end in the longitudinal direction, one end and the other end of the groove opening 10a which is inclined at the same angle to the axial direction of the magnetic vehicle 7 enters the tooth base portion 8a. The configuration of the other motor 1C is the same as that of the motor 1A. Here, with respect to the circumferential direction of the yoke 7, one end in the axial direction of the magnetic vehicle 7, in other words, the groove opening 10a at the position most in the axial direction of the magnetic vehicle 7 where the groove opening 10a of the tooth base portion 8a is located is located. The center of the width direction is set to a° with respect to the angle between the center of one of the grooves 10 constituting the groove opening 10a and the tooth base portion 8a. That is, the groove opening 10a is formed such that the angle in the circumferential direction of the yoke 7 occupies an angle width equivalent to a 2a component. It is assumed that the value of a becomes small when the groove opening 10a is not made to enter the tooth base portion 8a. That is, the deflection angle of the groove opening 10a when the groove opening 10a is entered into the tooth base portion 8a can be made larger than that without the groove opening 10a entering the tooth base portion 8a. 14 323142 201223081 The opening of the electric motor 1C according to the third embodiment is such that the groove can be moved into the tooth base portion 8a, and the lower limit::: torque or torque ripple can be reduced. In addition, according to the third embodiment, the groove opening 1 〇 = the entire area 'the extension of the axial length of the magnetic vehicle 7 : = is explained, but the groove is opened == The end of the axis of the magnetic vehicle 7 is z-shaped delayed toward the other end. If the position of the groove opening 1 () a corresponding to the mountain is entered, the groove opening IGa can be set. Large skew angle ^ 轾: The predetermined part of the direction of the axis enters - to the two cores of the heart becomes It 8' and can be set as the groove opening = the axis side (four) large deviation (four) degrees, (4) the _ component (four) moments can be connected Fig. 9 is a diagram showing the relationship between the deflection angle and the skew coefficient with respect to the purchased axial direction in the fourth embodiment of the present invention. The present invention according to the fourth embodiment is the same: in addition, the number of poles and the number of grooves are any natural number 'the number of poles is set to 10Z, and the number of grooves is set to the angle of m::=, :3:-- 323142 15 201223081 (4) In the middle of the ', the horizontal axis is the non-phase of the groove opening 10a = the skew coefficient of the opening angle of the opening. ...Effect 2:: is the opposite of when the skew angle of the groove opening (10) is 0 =:=: when it is set to 1 - in addition, for example, the stator core 6A has a work & In the case of a difference, the cogging torque is generated due to the operational error of the stator iron S6A. This cogging torque is a rotation angle of the rotor 2, and has a period of (36/z) of the arrangement of the permanent magnets 4 as a periodic amplitude, and an interval of 1/2 of the first age (_ The second component of the periodic amplitude is shown in Fig. 9. The first component of the cogging torque due to the operational error of the stator core 6 a is indicated by a thick line, and the second component is indicated by a broken line. Indicates the component of the cogging torque caused by the number of poles in the number of poles: the number of slots = 1 〇: 12 o'clock. As shown in Fig. 9, the value of the skew coefficient is at the skew angle. In the case of soil (3k/Z)°, the component of the cogging torque due to the number of poles and the number of grooves is theoretically reduced. Therefore, according to the fourth embodiment, the groove opening i The skew angle of 〇a is set at ±(3k/Z)°, so the cogging torque can be effectively reduced. Here, in the motor 1A in which the number of grooves is 12Z, the tooth base 8a including the partition groove 10 is included. The mechanical angle of each of the grooves in the circumferential direction of the yoke 7 (hereinafter referred to as the mechanical angle per one groove) is (30/Z). The tooth base portion 8a of the adjacent groove 10 is regarded as the tooth base portion of each of the one side and the other side of the groove 10 on the side of the width 323142 201223081 direction and the other side. The mechanical angle of each groove includes i parts of the tooth base 8a. In a typical motor, the angle of the tooth base 8a in the mechanical angle of each groove is (15/Z). Z) Therefore, in the motor that does not let the groove opening l〇a enter the tooth base 8& and deflect, the skew angle of the groove opening l〇a is set to + (6/z^, On the other hand, as in the electric motor 1C of the third embodiment, the groove opening of one end side and the other end side in the axial direction is made 1〇a.

The skew angle of the groove opening 1〇a can be easily set to ±(6/Z)° and ±(9/Z)° by entering the tooth base portion 8a'. & X In the motor of the fourth embodiment, the number of poles is set to 1 〇z, the number of grooves is set to 12Z, and the skew angle is set to ± (pulse/2). In the motors of the second and third embodiments, the number of electric turns is set to 10Z, the number of grooves is set to 丨2Z, and the skew angle is set to ±(North/2). By.
