Abstract

The invention provides a modular motor for pre-winding high-slot full-rate winding of an electric vehicle, belonging to the technical field of automobile motors. Characterized by comprising a convex lens-shaped iron core, a non-magnetically conductive rotor iron core, a stator iron core, an excitation winding, an armature winding, etc., wherein the stator iron core has 6X stator poles of equal width on the inner side thereof, X is a positive integer, and the non-magnetically conductive rotor iron core has 4X circular arc grooves. The circular arc groove is embedded with a convex lens-shaped iron core formed by stacking silicon steel sheets, an excitation winding is wound on the stator iron core every other stator pole, an armature winding is wound on the other stator poles, a planar permanent magnet is embedded in the yoke connecting the two stator poles, and the permanent magnet has an included angle of 45 degrees with the circular arc tangential direction. The technology of the invention can realize that after the pre-wound winding is embedded on the broken stator pole, the stator core is bent into a circle and put into the motor housing.

Description

technical field [0001] The invention relates to a modular motor with pre-winding of high slot full rate windings for an electric vehicle, which belongs to the technical field of automobile motors. Background technique [0002] Energy saving and environmental protection are the eternal pursuit goals of automobiles. Today's social environment is deteriorating and energy shortages are becoming more and more prominent. The whole society's requirements for energy saving and environmental protection are promoting the development of new energy vehicles. As a representative of new energy vehicles, electric vehicles have gradually become the main direction of development. Drive motor is one of the key technologies to be studied in electric vehicles. The improvement of motor efficiency can increase the mileage of the car, reduce the failure caused by motor heating and prolong the life. [0003] Automobiles, especially military vehicles, require automotive motors to have high reliab...
