Abstract

The invention discloses a switched reluctance motor for a new energy automobile, and particularly relates to the field of motor device; the switched reluctance motor comprises a motor body, wherein amotor control device is arranged on the outer side of the motor body; the motor control device comprises a control module, a control circuit, a driving circuit, a power converter, a current detectionmodule, a power circuit and a load module; a control switch is arranged at the top of the motor body; and an alarm is arranged at the bottom of the motor body. The motor control device and the alarm are arranged; the power converter in the motor control device is directly connected with the motor body in series through the power circuit and the load module, so that the direct-current short circuitphenomenon is avoided fundamentally; the protection circuit of the power circuit can be simplified, so that the cost is lowered; and meanwhile, the current detection module can detect whether the transmission current of the power supply circuit is stable or not, when the detection numerical value is abnormal, the control module can control the alarm to ring to remind a user, so that the switchedreluctance motor is suitable for frequent starting and stopping and forward and reverse conversion operation.

Description

technical field [0001] The invention relates to the technical field of motor devices, and more specifically, the invention relates to a switched reluctance motor for new energy vehicles. Background technique [0002] Switched reluctance motors have been used in electric vehicles due to their simple and solid structure, flexible control, wide speed range, and strong fault tolerance. Due to the large radial force generated during the operation of the traditional switched reluctance motor, high torque ripple and noise are caused. In order to overcome the problem of large torque ripple during the operation of the switched reluctance motor, the motor is currently improved by using a cascade connection. [0003] The invention patent of patent application publication number CN201810297030 discloses a cascaded switched reluctance motor for electric vehicles. By arranging segmented stators and segmented rotors in axial cascade, the number of stators and rotors can be changed. High ...
