[0027] specific implementation plan
[0028] The present invention will be further described below in conjunction with the accompanying drawings.
[0029] Such as figure 1 Shown is a diagram of an electrically excited salient pole motor for an electric vehicle of the present invention, the shown motor includes a shaft, a rotor core, a stator core, a main armature winding, a compensating armature winding, an excitation winding and a motor casing, and the salient pole motor It is an inner rotor structure.
[0030] A rotor core is fixed on the shaft, and 3n rotor poles are evenly distributed on the rotor core, where n is a positive integer; a stator core is fixed inside the motor housing, and 4n stator poles are evenly distributed on the side of the stator core facing the rotor core.
[0031] Two compensation slots with exactly the same size and shape are opened on one side of each stator pole facing the rotor core.
[0032] The top of the compensation groove facing the side o...

An electrically excited salient pole motor for an electric vehicle, characterized in that it includes a shaft, a rotor core, a stator core, a main armature winding, a compensating armature winding, an excitation winding, and a motor casing; rotor cores are fixed on the motor shaft, 3n pieces The rotor poles are evenly distributed on the rotor core, n is a positive integer; the stator core is fixed inside the motor housing, and 4n stator poles are evenly distributed on the side of the stator core facing the rotor core; each stator pole faces the side of the rotor core Open two compensation slots with the same size and shape; the compensation slots divide a stator pole into three parts, and the ratio of the pole arc length is 0.25:0.5:0.25; the main armature coil is wound from the stator pole side and from the stator pole The other side is wound out; the compensation armature coil is respectively wound in from the two compensation slots and wound out from the side of the main armature winding out of the stator pole. Compared with the traditional electric excitation salient pole motor, the technology of the present invention adopts a long-distance main armature winding and a short-distance compensation armature winding to effectively reduce the torque ripple of the electric excitation salient pole motor.
Description
technical field [0001] The invention relates to an electrically excited salient pole motor for an electric vehicle, belonging to the technical field of automobile motors and electrical appliances. Background technique [0002] With the increasingly serious problems of environmental pollution and energy depletion, finding new energy sources to replace fossil fuels has become a hot topic in research all over the world. Due to the characteristics of energy saving and environmental protection of new energy vehicles, related technologies and industries are developing rapidly. Compared with hybrid vehicles, pure electric vehicles use a single electric energy source, and the internal structure is greatly simplified because there is no mechanical transmission system. At the same time, the mechanical loss and noise of the vehicle are also reduced. It is the main development direction of new energy vehicles today. . [0003] An electric vehicle refers to a vehicle powered by a vehic...
