Embodiment Construction

[0030] The invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] figure 1 It is a structural schematic diagram of the electric vehicle short magnetic circuit short moment winding motor of the present invention

[0032] Includes sector core, cast aluminum rotor, stator core, field winding, armature winding and shaft.

[0033] There are 12X equal-width stator poles inside the stator core, where X is a positive integer, and in this example, X=1.

[0034] The cast aluminum rotor is located inside the stator core and fixed on the shaft; the cast aluminum rotor has 9 fan-shaped grooves; the fan-shaped grooves are embedded with magnetically conductive fan-shaped iron cores, and there are several dovetail-shaped protrusions on the bottom of the fan-shaped iron cores. The protrusion is embedded in the bottom of the fan-shaped groove; the fan-shaped iron core is formed by laminating fan-shaped silicon steel sheets;

Abstract

The invention provides a short magnetic circuit short torque winding motor of an electric vehicle, belonging to the technical field of automobile motors. The short magnetic circuit short torque winding motor is characterized by comprising a sector core, a cast aluminum rotor, a stator core, excitation windings, armature windings, and a shaft, wherein the stator core is internally provided with 12Xstator poles of equal width, X is a positive integer, a sector groove of the cast aluminum rotor is internally embedded with a magnetically conductive sector core, the bottom of the sector core is provided with a plurality of dovetail-shaped bulges, both the excitation windings and the armature windings are centralized short torque windings, one excitation winding is wound on the stator core every two stator poles, and the armature winding is wound on a stator pole between two excitation windings. The short magnetic circuit motor is low in iron loss under identical magnetic density; the windings are short torque windings, so that a lot of copper material is saved, the generator produces less heat but works more efficiently; only one phase of winding is outside each stator tooth of the motor, windings are not overlaid, slots are used more efficiently, and slot fill factor is high.

Description

technical field [0001] The invention relates to a motor with short magnetic circuit and short torque winding for 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. 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. The loss of the motor is mainly iron loss and copper loss. Iron loss is mainly generated by the iron core. Copper loss is mainly generated by the winding. [0003] Permanent magnet motors ...
