Abstract

The invention provides a synchronous reluctance motor rotor structure, a motor and a compressor. The synchronous reluctance motor rotor structure comprises a rotor core, first type slit grooves and second type slit grooves are set in the rotor core, the first type slit grooves and the second type slit grooves are alternately arranged in the q axis direction of the rotor core, wherein two ends of each of the first type slit grooves are provided with two filling slit grooves, and the second type slit grooves are air grooves. By setting the first type slit grooves and the second slit grooves, setting the filling slit grooves at two ends of the first type slit grooves and setting the second type slit grooves to be the air grooves, the efficiency of the motor with the rotor structure can be effectively improved, at the same time, the rotor structure can avoid the severe deformation during manufacturing, the amount of materials used for manufacturing the rotor structure can be reduced, and therefore, the production cost of the motor is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of compressor equipment, in particular to a synchronous reluctance motor rotor structure, a motor and a compressor. Background technique [0002] The asynchronous start synchronous reluctance motor combines the structural characteristics of the induction motor and the synchronous reluctance motor. The torque is generated by the squirrel cage induction to realize the start, and the multi-layer reluctance groove is set on the rotor to generate the reluctance torque to realize the constant speed operation. Turn on the power to start the operation. Compared with the permanent magnet motor, the asynchronous start synchronous reluctance motor has no rare earth permanent magnet material, and there is no problem of demagnetization. The motor has low cost and good reliability. Moreover, many air magnetic barriers are arranged on the rotor of the motor, so that the cooling effect is good and the loss of the rotor is ...
