Abstract

The invention relates to a high-power efficient motor used for an electric vehicle. The high-power efficient motor comprises a stator and a rotor, wherein the stator comprises a plurality of silicon steel sheets formed in a stamping and stacking mode, large pear-shaped stator tooth grooves are arranged in the silicon steel sheets, and stator windings are arranged in the large pear-shaped stator tooth grooves; the rotor is arranged on the outside of the stator and comprises a rotor rim and a plurality of concentric tile-shaped magnetic steel sheets attached to the inner side of the rotor rim in an adhesive mode, and air gaps are formed between the magnetic steel sheets and the silicon steel sheets. The motor has the advantages of high performance, a high material utilization rate and low magnetic energy loss; on the basis that the rotor guarantees that the performance of the motor meets work requirements, the quantity of magnetic steel sheet rare earth materials which are used is generally lower than that of a motor of the same specification; the groove model of the steel sheets is suitable for various pole-slot ratios and line insertion schemes, and the rotation speed and the power span are large.

Description

technical field [0001] The invention relates to the technical field of motors, and more specifically, the invention relates to a high-power and high-efficiency motor for electric vehicles. Background technique [0002] The stator and rotor are the core components of the motor. According to the electromagnetic principle, the energized coil generates a resolver magnetic field, forming an unbalanced magnetic field torque, and causing the motor to generate directional rotation. Whether the structure between the stator and the rotor is reasonable or not is related to the material utilization rate of the motor, and the rational design of the magnetic circuit of the stator groove can greatly improve the energy conversion utilization rate of the motor. The precise motor stator and rotor structure can effectively reduce various losses of the motor, such as air gap loss, iron loss, copper loss, etc., on the premise of ensuring the qualified performance of the motor. Waste of stator s...
