Embodiment Construction

[0035] The invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] figure 1 It is a structural schematic diagram of the electric vehicle modular stator-rotor motor of the present invention. Among them, F, A, B and C represent the excitation winding and the A-phase armature winding, the B-phase armature winding and the C-phase armature winding respectively, and the negative sign indicates that the winding direction is opposite.

[0037] The electric vehicle modular stator-rotor motor includes a sector core, a non-magnetic rotor core, a stator core, an excitation winding, an armature winding and a shaft;

[0038] The stator core is divided into 6 E-shaped stator modules, and each stator module has 3 stator poles with different widths inside, the middle one is the field pole, and the two sides with equal width are the armature poles. The field pole width is greater than 1.2 times of the armature pole and less than 1.5 times of...

Abstract

The invention provides an electric automobile modular stator and rotor motor, and belongs to the technical field of automobile motors. The electric automobile modular stator and rotor motor is characterized by comprising a convex lens-shaped iron core, a non-magnetic-conduction rotor iron core, a stator iron core, an excitation winding, an armature winding and the like, wherein the stator iron core is divided into six stator modules which are E-shaped; three unequal-width stator poles are arranged on the inner side of each stator module, wherein an excitation pole is arranged in the middle, and armature poles of the same width are arranged on the two sides; the non-magnetic-conduction rotor iron core has 10 fan-shaped grooves; and fan-shaped iron cores formed by silicon steel sheets in a laminated mode are embedded in the fan-shaped grooves. By virtue of the technology of the invention, a magnetic field can be provided for two armature windings through a short-moment excitation winding, so that the winding groove fullness and the isolation performance of each phase are improved, and the design of modularization of the stator and the rotor is realized.

Description

technical field [0001] The invention relates to a modular stator-rotor motor of an electric vehicle, which belongs to the technical field of automobile motors. Background technique [0002] Today's social environment is deteriorating and energy shortages are becoming more and more prominent. Therefore, the eternal goal of automobiles is to be more energy-efficient and more environmentally friendly. The development of electric vehicles is a global consensus. Drive motor is one of the key technologies to be studied in electric vehicles. Overall, motors are developing in a more efficient and reliable direction. [0003] In terms of efficiency, the improvement of motor efficiency can increase the driving range of the car, reduce the failure caused by motor heating and prolong the life. The loss of the motor is mainly iron loss and copper loss. The iron loss is mainly generated by the iron core. Copper loss is mainly generated by the winding. Permanent magnet motors can imp...
