Abstract

The invention provides a stator assembly and a hybrid excitation motor. The stator assembly comprises a stator core, a winding ring, a magnetic conduction support and an excitation winding which are coaxially arranged, wherein the winding ring, the magnetic conduction support and the excitation winding are all arranged at one end of the stator core, the magnetic conduction support sleeves the winding ring, the winding ring is made of a non-magnetic conduction material, the magnetic conduction support is made of a magnetic conduction material, a winding space is formed between the winding ringand the magnetic conduction support, and the excitation winding is arranged in the winding space. The hybrid excitation motor comprises the stator assembly. Except the hybrid excitation motor has theadvantages of good speed regulation performance, high demagnetization resistant capability, high material utilization ratio and high efficiency of a traditional hybrid excitation motor, the problem ofmagnetic saturation near to an excitation winding can be effectively reduced by the winding ring and the magnetic conduction support in the stator assembly, and the weak magnetic capability of the motor is improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a stator assembly and a hybrid excitation motor with the stator assembly. Background technique [0002] Axial / radial magnetic circuit hybrid excitation synchronous motors can effectively solve the problems of high heat generation at low speeds of automobile drive motors, difficulty in field weakening and easy demagnetization at high speeds. The excitation winding of this type of motor is placed in the axial middle of the stator through the magnetically permeable bracket, and the axial passage is formed through the magnetically permeable casing or the magnetically permeable ring. When the excitation winding is energized, the magnetic field generated by the permanent magnet and the magnetic field generated by the electric excitation must form a loop through the axial direction. If the excitation current is too large, the magnetic density of the magnetic ring or the magnetic casing n...
