Abstract

The invention provides a rotor structure of a self-starting hybrid excitation permanent magnet auxiliary reluctance motor and the motor. The rotor structure comprises a rotor iron core, a plurality ofmagnetic barrier grooves are formed in the rotor iron core, a permanent magnet is arranged in at least one magnetic barrier groove in the plurality of magnetic barrier grooves, and a non-magnetic conductor is arranged in at least one magnetic barrier groove in the rest of the plurality of magnetic barrier grooves. The permanent magnet auxiliary reluctance motor with the structure has an out-of-step protection function. Due to the fact that the non-magnetic conductor is arranged in the rotor iron core, the non-magnetic conductor has a damping winding effect, when the motor operates synchronously, transient impact currents of the rotor in various abnormal states can be guided to the end of the rotor to be offset and returned to zero, and the effects of avoiding rotor structure heating and magnetic steel demagnetization are achieved. By adopting the rotor structure of the structure, the efficiency and the practicability of the motor are effectively improved.

Description

technical field [0001] The invention relates to the technical field of motor equipment, in particular to a rotor structure and a motor of a self-starting hybrid excitation permanent magnet assisted reluctance motor. Background technique [0002] Permanent magnet assisted reluctance motors are currently one of the development directions of permanent magnet synchronous motors, and reluctance compressors with ferrite assisted magnets in the field of household appliances are gradually replacing DC rare earth compressors. In the field of industrial motors, industrial reluctance motors are replacing YE3 induction motors, and rare earth permanent magnet synchronous motors driven by automobiles may also be replaced by permanent magnet assisted reluctance motors. [0003] At present, industrial permanent magnet assisted reluctance motors have been used in water pumps or fans. Bus drive motors are motors with high power and high output torque. Generally, rare earth permanent magnet sy...
