Definitions
- the present invention relates to a three-phase synchronous reluctance motor.
- FIG. 14 illustrates a cross-sectional structure of a stator 310 of a general reluctance motor.
- the magnetic path width W on the back yoke side of the teeth 311 of the stator In order to equalize the tonnolek generated in the rotating rotor of the reluctance motor, it is necessary to set the magnetic path width W on the back yoke side of the teeth 311 of the stator to be uniform over the entire circumference. You. However, a bolt hole 312 as shown is provided for fixing the reluctance motor and for fixing with a bracket (not shown) having a rotor bearing portion, that is, for improving handling properties. In that part, the magnetic path width W on the back yoke part side cannot be set uniformly over the entire circumference.

- a core cut portion 412 is formed on an outer peripheral portion of a stator 410 for the purpose of reducing material costs and improving handling properties. Then, along with the formation of the core cut portion 412, it is protruded to the side of the tooth portion 411 on the inner peripheral side of the stator 410 for the purpose of securing the magnetic passage width W of the stator 410 to the same level as before the core cut.
- a part 413 is provided.
- Patent Document 1 JP-A-2000-350390 (FIG. 10)
- the magnetic path width W Although it can be made substantially uniform over the entire length, the side of the teeth where the stator winding is to be wound is protruded, and the stator winding cannot be wound there. As a result, in this stator, there is a problem in that the winding dose of the stator winding is reduced, the linkage flux is reduced, and the torque is reduced. Therefore, in order to output sufficient tonnolek, the motor must be enlarged.
- the present invention has been made in view of the above problems, and an object of the present invention is to form a back yoke portion of a stator so as to be partially narrow so as to reduce the size of the stator.
- An object of the present invention is to provide a three-phase synchronous reluctance motor that prevents a magnetic resistance from being too large in a magnetic path of a shock yoke portion.
- a three-phase synchronous reluctance motor includes a stator having a motor and a plurality of teeth facing the rotor along a circumferential direction of an inner surface.
- One tooth of the plurality of rotor magnetic poles of the rotor is opposed to each of the six teeth, and a stator winding having a coil pitch of five teeth among the six teeth. Is wound.
- the width of the magnetic path in the back yoke portion of the stator corresponding to the adjacent tooth portion adjacent to the tooth portion corresponds to the other tooth portion.
- the present invention is characterized in that at least one narrow portion which is smaller than the width of the magnetic passage portion in the back yoke portion of the stator is provided.
- the tooth With respect to the tooth portion between the adjacent stator windings so as to form magnetic poles having the same phase and different polarities as in the above-described characteristic configuration, the tooth is located on the back yoke portion of the adjacent tooth portion adjacent to the tooth portion.
- the position of the narrow portion is different from the position where the magnetic flux concentrates most in the magnetic path portion.
- the magnetic resistance does not increase significantly at the position where the narrow portion is provided. Therefore, the chain It is possible to sufficiently secure the tonnolek output by the three-phase synchronous reluctance motor, which does not greatly reduce the magnetic flux.
- a three-phase synchronous reluctance motor includes a rotor and a stator having a plurality of teeth facing the rotor along a circumferential direction of an inner surface, and includes a plurality of rotor magnetic poles of the rotor.
- a three-phase synchronous reluctance motor in which six teeth are opposed to each other, and a stator winding having a coil pitch of five teeth of the six teeth is wound.
- the width of the magnetic path portion in the back yoke portion of the stator corresponding to the tooth portion between two adjacent stator windings that form magnetic poles having the same phase and different polarities. May be provided by providing at least one narrow portion that is narrower than the width of the magnetic path portion in the back yoke portion of the stator corresponding to the other tooth portions.

- the formation range of the narrow portion along the pitch is not more than two pitches of the tooth portion.
- the narrow portion is formed in a range of two pitches or less of the tooth portion, the range in which the magnetic resistance increases is limited, and the magnetic field at the position where the magnetic flux originally concentrates is limited. Further narrowing of the passage width can be avoided. For this reason, it is possible to prevent the magnetic resistance of the back yoke portion from becoming excessive.
- Still another characteristic configuration of the three-phase synchronous reluctance motor according to the present invention is that a pitch of the plurality of narrow portions along a circumferential direction of the stator is smaller than a pitch of the rotor magnetic pole. n / 3 (n is a natural number).
- the back yoke is used during two-phase rectangular wave driving and three-phase driving.
- the position where the magnetic flux is most concentrated in the section exists at a pitch of 1/3 of the pitch of the rotor magnetic poles. Therefore, if the narrow portion is provided at a pitch of every n / 3 of the pitch of the rotor magnetic poles, it is possible to prevent the position where the magnetic flux is most concentrated and the position of the narrow portion from overlapping in the back yoke portion. .
- the reluctance is greatly increased in the magnetic path.
