Switch reluctance motor and vehicle power motor assembly

Abstract

The invention provides a switch reluctance motor and a vehicle power motor assembly. The switch reluctance motor comprises a stator and a rotor, the stator comprises multiple stator magnetic poles uniformly distributed peripherally, each stator magnetic pole comprises a first stator magnetic pole unit and a second stator magnetic pole unit, each first stator magnetic pole unit comprises a first stator magnetic pole root portion extending axially and multiple first stator magnetic pole tooth portions radially extending from the first stator magnetic pole root portion to the rotor, and each second stator magnetic pole unit comprises a second stator magnetic pole root portion extending axially and multiple second stator magnetic pole tooth portions radially extending from the second stator magnetic pole root portion to the rotor; the rotor comprises multiple rotor magnetic poles uniformly distributed peripherally, each rotor magnetic pole comprises a rotor magnetic pole root portion, multiple first rotor magnetic pole tooth portions and multiple second rotor magnetic pole tooth portions, the first rotor magnetic pole tooth portions extend peripherally from one side of the corresponding rotor magnetic pole root portion, and the second rotor magnetic pole tooth portions peripherally extend from the other side of the corresponding rotor magnetic pole root portion.

Description

technical field [0001] The invention relates to the field of switched reluctance motors, in particular to a switched reluctance motor integrated with a hollow rotor structure and an automotive power motor assembly including the switched reluctance motor. Background technique [0002] At present, more and more people begin to pay attention to the application of switched reluctance motor. However, the traditional switched reluctance motor still has the following disadvantages: 1. The radial vibration generated by the traditional switched reluctance motor during operation and the salient pole structure of the stator and rotor are the main reasons for the noise of the switched reluctance motor; 2. 1. The torque ripple generated by the traditional switched reluctance motor during operation is the main reason for the unstable operation and low efficiency of the switched reluctance motor; 3. The power density of the traditional switched reluctance motor is not high; 4. The traditio...
