First, the structure of Fig. 1 ~ Fig. 5 to the rotary type permanent-magnet motor of the first execution mode of the present invention is utilized to be described.Fig. 1 is the sectional view of the axial rotary of the structure of the stators and rotators representing the first execution mode of the present invention.Fig. 2 be Fig. 1 revolution to the major part enlarged drawing in 1/6 region.Fig. 3 is the sectional view of the radial direction of the rotary type permanent-magnet motor of the first execution mode of the present invention.Fig. 4 represents that the hole unshakable in one's determination of rotor core of the present invention is on the figure of the definition of the variable used in the calculating of the impact that torque performance produces.Fig. 5 is the figure of the result of calculation representing Fig. 4.
In FIG, rotary type permanent-magnet motor 1 comprises stator 2, rotor 3 and the second non-magnetic member 100.
Stator 2 comprises stator core 21 and stator winding 22 in fig. 2.The electromagnetic steel plate that stator core 21 is obtained by stamping-outs such as utilizing blanking die (punch cutting die) is stacked and form on axial rotary.Stator core 21 comprise the magnetic circuit of the formation stator 2 of the peripheral part being located at stator 2 stator core rear portion (core back) 23 and to specify angular pitch (pitch) radially from stator core rear portion 23 to the stator salient poles (stator salientpole) 24 that the inner circumferential of stator 2 is extended.As shown in Figure 2, the space be made up of between adjacent a pair stator salient poles 24 and stator core rear portion 23 is groove 25, and it is the space of storage stator winding 22.At this, in each stator salient poles 24, extremely go up winding stator winding 22 for one.
On the other hand, rotor 3 relatively configures across air gap 4 in the radial direction of stator 2.Axle (shaft) 35 is attached to rotor 3.At the outer peripheral face of axle 35, the inner circumferential side of rotor 3 is configured with the first non-magnetic member 36.The outer peripheral face of the first non-magnetic member 36 is located at by rotor 3, is included in revolution and is upwards divided into multiple rotor cores 31 and is upwards divided into multiple permanent magnets 34 at revolution.Permanent magnet 34 and rotor core 31 are alternately configured in revolution upwards radially respectively to the periphery of rotor 3.The electromagnetic steel plate that rotor core 31 is such as obtained by stamping-outs such as utilizing blanking die is stacked and form on axial rotary.As shown in the figure, rotor core 31 at revolution upwards by the segmentation of each pole, along the revolution of rotor 3 to specify angular pitch spread configuration.Rotor core 31 plays a role as the rotor magnetic pole 32 of the magnetic circuit forming rotor 3.
As shown in the figure, the space be made up of adjacent a pair rotor magnetic pole 32 and the first non-magnetic member 36, namely magnet inserts in space 33 and is accommodated with permanent magnet 34.The magnetization of permanent magnet 34 now, towards the direction at a right angle with the radial direction of rotor 3, is configured to the revolution of rotor magnetic pole 32 along rotor 3 to alternately becoming NSNS ...Permanent magnet 34 anchors at magnet by bonding agent etc. and inserts space 33.
Rotor core 31 is entrenched in described first non-magnetic member 36 at the peripheral part of the first non-magnetic member 36.First non-magnetic member 36 utilizes the keyway of the outer peripheral face of axle 35 (keyway) (not shown) to fix.First non-magnetic member 36 has the effect of the leakage flux of the inner circumferential side of reducing rotor magnetic pole 32.The torque acting on rotor core 31 is delivered to axle 35 via the first non-magnetic member 36.Hole unshakable in one's determination 37, first non-magnetic member 36 that rotor core 31 has a through rotor core 31 on the axial rotary of rotor 3 has the non magnetic piece bores 38 of through first non-magnetic member 36 on the axial rotary of rotor 3.In the present embodiment, the torque acting on the outer circumferential side of rotor core 31 is according to the sequence delivery of the fitting portion → the first non-magnetic member 36 → axle 35 of rotor core 31 → rotor core 31 and the first non-magnetic member 36.When the present embodiment, the main bang path of torque is not bar (bar), therefore compared with prior art can not increase bar.
In Fig. 3, stator 2 is fixed on frame (frame) 5 via stator core rear portion 23 on axial rotary, and the axle 35 linked with rotor 3 is arranged on frame 5 via bearing 6.In addition, at rotor 3, axial rotary is connected with the encoder (encoder) 7 of the control for carrying out rotary type permanent-magnet motor 1.Axle 35 is attached to rotor 3.Side plate 39 is attached to axle 35.Side plate is configured with in the side of the axial rotary of two the second non-magnetic member 100.
Be provided with two the second non-magnetic member, 100, two the second non-magnetic member 100 to be linked on axial rotary by hole 37 unshakable in one's determination and non magnetic piece bores 38 in the both sides of the axial rotary of rotor 3.
As shown in above structure, by utilizing the outer circumferential side of the second non-magnetic member 100 fixed rotor iron core 31, can weaken the magnetic stress of the outer peripheral face because acting on rotor core 31 rotation circumferential component and produce, the moment of flexure of the fitting portion of rotor core 31 and the first non-magnetic member 36, the intensity of the fitting portion of rotor core 31 and the first non-magnetic member 36 can be guaranteed.In addition, owing to also having the effect of the electromagnetic viscosimeter suppressing rotor core 31, therefore low noise can be realized.In addition, when rotor core 31 uses ferrite lattice (ferrite magnet), by the breakage suppressing the vibration of rotor core 31 can prevent ferrite lattice, can prevent the magnetic of magnet from flying out in air gap 4.
The degree of depth of the radial direction of the fitting portion of rotor core 31 and the first non-magnetic member 36 is more shallow, when the front end geometry of the inner circumferential side of rotor core 31 is sharper, when manufacturing rotor 3, the location of rotor core 31 becomes difficulty, the external diameter circularity (roundness) of rotor 3 is deteriorated, and is difficult to realize low torque ripple.So, as shown in this embodiment, by making the fitting portion of rotor core 31 and the first non-magnetic member 36 be dovetail (dovetail) structure, the location transfiguration of rotor core 31 is easy, the external diameter circularity of rotor 3 can be improved, therefore, it is possible to realize low torque ripple.
Fig. 4 and Fig. 5 represents the impact that the hole unshakable in one's determination 37 of rotor core 31 is brought torque performance.As shown in the figure, on the symmetry axis of the radial direction of rotor core 31, the distance that order links between the adjacent outer circumferential side of a pair permanent magnet 34 and two lines at the angle of inner circumferential side is a, makes the distance from the line of the inner circumferential side of permanent magnet 34 to the central point in hole 37 unshakable in one's determination be b.Utilize the magnetic field analysis based on seamed edge unit's Finite Element (edge-element finite element method), calculate the change of torque when making a be definite value and b is changed.
In the present embodiment, it is thousands of Nm ranks that imagination produces torque, therefore have estimated corresponding magnetic stress therewith, makes the size in hole 37 unshakable in one's determination corresponding to (corresponding to) M6, M8 bolt.Represent torque reduced rate when outputing the unshakable in one's determination hole 37 corresponding to M6 bolt with solid line in Figure 5, be represented by dotted lines torque reduced rate when outputing the unshakable in one's determination hole 37 corresponding to M8 bolt.According to the result in figure, more at outer circumferential side, then torque is less in the position in hole 37 unshakable in one's determination, and the larger then reduced rate in hole 37 unshakable in one's determination is less.At this, when torque reduced rate allow to 3%, the position in the unshakable in one's determination hole 37 corresponding to M6 bolt can be configured to until 95% (representing with the value of b/a × 100) left and right, and the position in the unshakable in one's determination hole 37 corresponding to M8 bolt can be configured to until about 75%.If the position in hole 37 unshakable in one's determination is less than 50%, then the effect that weakens of the moment of flexure of the fitting portion of rotor core 31 and the first non-magnetic member 36 diminishes, therefore expect that the position in hole 37 unshakable in one's determination is more than 50%, less than 95%, be preferably more than 70%, less than 95%, more preferably more than 90%, less than 95%.In addition, in the scope of the position in hole 37 unshakable in one's determination, on the position 95% of weakening the maximum hole unshakable in one's determination 37 of effect of the moment of flexure of the fitting portion of rotor core 31 and the first non-magnetic member 36, the unshakable in one's determination hole 37 corresponding to M6 bolt is at about 30% of revolution width upwards by the rotor core 31 at the center in this hole 37 unshakable in one's determination at revolution width upwards, therefore expect that the rotation circumferential width in hole 37 unshakable in one's determination is less than 35% of the width of the circumference of the rotor core 31 at center by this hole 37 unshakable in one's determination, be preferably more than 28%, less than 32%.
When the outer peripheral face of axle 35 is difficult to make keyway, two the second non-magnetic member 100 can be made by non magnetic piece bores to be attached to the side plate 39 linked with axle 35, to transmit torque to axle 35 via side plate 39.Thereby, it is possible to the intensity realizing the fitting portion of rotor core 31 and the first non-magnetic member 36 is guaranteed and to the transmission of torque of axle 35 simultaneously.
[embodiment 2]
Utilize Fig. 6 and Fig. 7, the structure of the rotary type permanent-magnet motor of the second execution mode of the present invention is described.Fig. 6 is the sectional view of the axial rotary of the structure of the stators and rotators representing the present embodiment.Fig. 7 is the sectional view of the radial direction of the rotary type permanent-magnet motor of the present embodiment.
In figure 6 and figure 7, two the second non-magnetic member 100 utilize pin 110 to be linked on axial rotary by the hole unshakable in one's determination 37 of rotor core 31, utilize bolt 120 to be linked on axial rotary by the non magnetic piece bores 38 of the first non-magnetic member 36, link with side plate 39.
In the rotary type permanent-magnet motor of multipole as shown in this embodiment, owing to having multiple rotor core 31, the number in hole 37 unshakable in one's determination becomes many, to they all be utilized bolt 120 to link, then there is the problem that production lead time (lead time) increases considerably.To this, by using pin 110, multiple link operation can be carried out simultaneously, producing the lead time therefore, it is possible to shorten.The shape of pin 110 can be not only the circle in figure, can also be polygon.But, in rectangular situation, by making the direction on long limit configure towards radial side, fluidly link two the second non-magnetic member 100 of magnetic flux can not be hindered.
On the other hand, because the number of the non magnetic piece bores 38 of the first non-magnetic member 36 is fewer than the number in hole 37 unshakable in one's determination, even if therefore use bolt 120 also can not increase considerably produce the lead time.In it is possible to use bolt 120 in the non magnetic piece bores 38 of the first non-magnetic member 36, realize the maintenance of rotor core 31 and the transmission of torque simultaneously.In addition, in order to torque is delivered to side plate 39 from the second non-magnetic member 100, need the fastening force guaranteed on the axial rotary of the first non-magnetic member 36, second non-magnetic member 100 and side plate 39, therefore compared to use pin 110, use bolt 120 more can guarantee the fastening force on axial rotary, can carry out stable transmission of torque.
Show in the present embodiment revolution to all-round in hole 37 unshakable in one's determination and non magnetic piece bores 38, use the example of pin 11 and bolt 120, but need not all to use.When the intensity of the fitting portion of rotor core 31 and the first non-magnetic member 36 has nargin (having more than needed), such as, can adopt the method upwards using pin 110 and bolt 120 at revolution every.

In fig. 8, two the second non-magnetic member 100 are upwards divided at revolution, each second non-magnetic member 100 divided have the part that two places are linked by the non magnetic piece bores 38 of the first non-magnetic member 36.
By upwards splitting the second non-magnetic member 100 at revolution, the rate of finished products of material can be improved.In addition, the part linked by the non magnetic piece bores 38 by the first non-magnetic member 36 making divided second non-magnetic member 100 have more than two places, the electromagnetic viscosimeter that the inner circumferential side that can reduce the second non-magnetic member 100 produces, realizes low noise.
As the further countermeasure improving the finished material rate of the second non-magnetic member 100, there is the structure of Fig. 9 and Figure 10.In Fig. 9, divided second non-magnetic member 100 has the 21 non-magnetic member 300 of the shape covering hole 37 unshakable in one's determination and non magnetic piece bores 38 on axial rotary and on axial rotary, covers hole 37 unshakable in one's determination and make the two or two non-magnetic member 310 two kinds that non magnetic piece bores 38 is exposed.In other words, the two or two non-magnetic member 310 is in the shape only covered near hole 37 unshakable in one's determination.Upwards alternately configure the 21 non-magnetic member the 300 and the 22 non-magnetic member 310 two kinds at revolution, the 21 non-magnetic member 300 is linked by hole 37 unshakable in one's determination and non magnetic piece bores 38, and the two or two non-magnetic member 310 links by means of only hole 37 unshakable in one's determination.
Figure 10 is the structure of the two or two non-magnetic member 310 to the 21 non-magnetic member more than 300.The use amount of the second non-magnetic member 100 can be reduced thus.
Owing to upwards acting on the two or two non-magnetic member 310 at revolution effectively, so power is delivered to the 21 non-magnetic member 300 via the two or two non-magnetic member 310 upwards adjacent at revolution, the intensity being attached to the rotor core 31 of the two or two non-magnetic member 310 and the fitting portion of the first non-magnetic member 36 can be guaranteed thus.
When the structure of Fig. 9 and Figure 10, due to the uneven weight (unbalance weight) of rotor 3, the vibration of rotor 3 becomes problem.So, by making the side of two the second non-magnetic member 100 link at the revolution certain angle that upwards staggers, thus uneven weight being disperseed, the vibration of rotor 3 can be prevented.When Fig. 9, only make the side of two the second non-magnetic member 100 upwards stagger 60 degree at revolution and carry out linking.In case of fig. 10, only make the side of two the second non-magnetic member 100 upwards stagger 90 degree at revolution to carry out linking.
