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, q-axis squirrel cage slots areset near an outer edge of the rotor core, a plurality of slit slots are arranged between the q-axis squirrel cage slots and a shaft hole of the rotor core, two ends of each slit slots are provided with two squirrel cage slots, a first angle is set between a side wall of a squirrel cage slot at one side of a d axis and the d axis, and first angles are gradually increased outward in the radial direction of the rotor core. Through the above setting, the q-axis reluctance can be increased, the q-axis inductance can be reduced, the difference of magnetic flux between the d axis and a q axis is reduced, a larger reluctance torque is generated, and the motor output and efficiency are increased.

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] 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, the patent publication No. CN1255925C provides a cheap and easy-to-start synchronous induction motor and a manufacturing device an...
