Abstract

The present invention provides a rotor structure, an asynchronous starting synchronization reluctance motor and a compressor. The rotor structure comprises a rotor body (10), the rotor body (10) is provided with holding grooves (11) and a magnetic barrier slit groove (13), one first magnetic flow channel (12), passing through a q axis, formed between each two adjacent holding grooves (11) has a width D3, D3>K, wherein K is the width of the stator teeth of the stator core. The width of the first magnetic flow channel (12) passing through the q axis is larger than the width of the stator teeth to avoid the supersaturation of the magnetic channel, ensure that the magnetic flow effectively enters a stator, allow the motor having the having the rotor structure to generate a larger reluctance torque and increase the output torque and the efficiency of the motor so as to improve the performances of the motor.

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...
