Problems solved by technology

However, the traditional switched reluctance motor still has the following disadvantages: 1. The radial vibration generated by the traditional switched reluctance motor during operation is the main cause of the noise of the switched reluctance motor; 2. The traditional switched reluctance motor is running The torque ripple generated in the motor 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 traditional four-phase or five-phase or more phase The control system of the switched reluctance motor is complex

Abstract

The invention provides a switched reluctance motor including a U-shaped rotor magnetic pole structure. The switched reluctance motor comprises a stator and a rotor, wherein the stator and the rotor are coaxially arranged. The stator comprises a number of stator magnetic poles uniformly distributed in the circumferential direction. Each stator magnetic pole comprises a stator magnetic pole root anda number of stator magnetic pole teeth extending radially from the stator magnetic pole root toward the rotor. Each stator magnetic pole is wound with a coil. The rotor comprises a number of rotor magnetic poles uniformly distributed in the circumferential direction. Each rotor magnetic pole comprises a rotor magnetic pole root and a number of rotor magnetic pole teeth extending in the circumferential direction from the same side of the rotor magnetic pole root, wherein the rotor magnetic pole teeth and the rotor magnetic pole root share the same curvature. A number of stator magnetic pole teeth and a number of rotor magnetic pole teeth are axially aligned with each other. According to the switched reluctance motor provided by the invention, radial vibration and torque ripple of the motor can be significantly reduced; noise generated by radial vibration can be reduced; and the motor efficiency is improved.

Description
