Abstract

The invention provides a rotor structure, an asynchronous starting synchronous reluctance motor and a compressor. The rotor structure comprises a rotor body; multiple accommodating grooves are formedin the rotor body; the multiple accommodating grooves are formed in the circumferential direction of the rotor body at intervals; the accommodating grooves extend in the q-axis direction; a first magnetic flux channel is formed between adjacent two accommodating grooves; the magnetic flux direction of the first magnetic flux channel is parallel to the q-axis direction; and the magnetic flux direction of the first magnetic flux channel is perpendicular to the d-axis direction. By enabling the accommodating grooves to be arranged in the q-axis direction, the q-axis magnetic flux can be in barrier-free circulation, so that the magnetic flux difference between the d-axis and the q-axis can be improved effectively, thereby enabling the motor with the rotor structure to generate higher reluctance torque, improving the output torque and efficiency of the motor, and further improving motor performance.

Description

technical field [0001] The invention relates to the technical field of motor equipment, in particular to a rotor structure, an asynchronously started synchronous reluctance motor and a compressor. Background technique [0002] Asynchronous start synchronous reluctance motor combines the structural characteristics of induction motor and reluctance motor. It can start by generating torque through squirrel cage induction, and realize constant speed operation by generating reluctance torque through rotor inductance gap. It can be directly connected to power supply to realize starting operation. Compared with the asynchronous start 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. [0003] In the prior art, at least a pair of slits of two-pole magnetic pole projections at 90 degrees between the q-axis in the direction in w...
