Abstract
The invention discloses a mixed excitation permanent magnet synchronous motor. The motor comprises a stator, and the stator comprises a stator winding, a stator core, and a stator back yoke. The stator core is axially divided by a DC annular exciting winding into an N-pole side iron core and an S-pole side iron core. The stator back yoke is connected with the N-pole side iron core and the S-pole side iron core. According to the embodiment of the invention, the motor has the electric excitation and brushless characteristics of a permanent magnet synchronous motor, integrates with the advantages of above two sides, irons out the defects of two sides, and can improve the performances to a greater extent.
Description
Technical field
The present invention relates to new-energy automobile manufacturing technology field, particularly relate to a kind of composite excitation permanent magnet synchronous motor.
Background technology
Along with economic develops rapidly, automobile has become one of important trip mode of people, and electric automobile is because of its distinctive advantage that can reduce air pollution, it has also become the study hotspot of current automotive industry.Electric automobile, under the working conditions such as starting, climbing, needs bigger output torque, and now the travel speed of automobile is slow；In the occasion of some high-speed cruisings, then needing in a bigger scope can the travel speed of invariable power regulation automobile.Therefore, if can be in conjunction with magneto and the advantage of electro-magnetic motor, improving existing motor be urgent problem of the present invention.
Summary of the invention
For solving the problems referred to above present in prior art and practical situation, the invention provides a kind of composite excitation permanent magnet synchronous motor, it is characterised in that synchronous motor includes that stator, described stator include stator winding, stator core and stator back yoke；Described stator core is divided into side, N pole unshakable in one's determination and side, S pole iron core two parts by direct current circular excitation winding in the axial direction；Described stator back yoke connection side, described N pole is unshakable in one's determination and side, described S pole unshakable in one's determination.
Preferably, the length that side, described N pole is unshakable in one's determination and side, described S pole is unshakable in one's determination is equal.
Beneficial effect:
A kind of composite excitation permanent magnet synchronous motor that the embodiment of the present invention provides, it has magneto, electrical excitation and brushless feature, the advantage comprehensively with the two simultaneously, overcomes again both respective defects simultaneously, can the performance of bigger raising motor.
Detailed description of the invention
Technical solution of the present invention is described in detail below.
The open a kind of composite excitation permanent magnet synchronous motor of embodiments of the invention, it is characterised in that synchronous motor includes that stator, described stator include stator winding, stator core and stator back yoke；Described stator core is divided into side, N pole unshakable in one's determination and side, S pole iron core two parts by direct current circular excitation winding in the axial direction；Described stator back yoke connection side, described N pole is unshakable in one's determination and side, described S pole unshakable in one's determination.
Further, the length that side, N pole is unshakable in one's determination and side, described S pole is unshakable in one's determination is equal.
A kind of composite excitation permanent magnet synchronous motor that the embodiment of the present invention provides, it has magneto, electrical excitation and brushless feature, the advantage comprehensively with the two simultaneously, overcomes again both respective defects simultaneously, can the performance of bigger raising motor.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention, although the present invention being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
