Abstract

The invention provides an asynchronous starting type synchronous reluctance motor rotor, a motor and a compressor. The asynchronous starting type synchronous reluctance motor rotor comprises a rotor iron core; the rotor iron core comprises a plurality of supplementing grooves (214) and a plurality of first magnetic barrier parts (21); the supplementing grooves (214) are located between the end parts of the first magnetic barrier parts (21) and the outer edge of the rotor iron core (10); a distance between the center (a d axis) of each first magnetic barrier part (21) and a q axis is C1; a distance between the supplementing grooves (214) in the two ends of each first magnetic barrier part (21) and the q axis is C2; and a ratio C1 / C2 of C1 to C2 is 1-5. The problem of low working efficiencyof the asynchronous starting type synchronous reluctance motor rotor of the motor in the prior art is effectively solved; and meanwhile, a proper supplementing groove proportion is set, so that the starting performance of the motor is guaranteed.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an asynchronous start synchronous reluctance motor rotor, motor and compressor. Background technique [0002] The synchronous reluctance motor with asynchronous start combines the structural characteristics of the induction motor and the reluctance motor. The torque is generated by the squirrel cage induction to realize the start, and the reluctance torque is generated by the rotor inductance gap to realize the constant speed operation of the motor, so that the motor can be directly connected to the power supply. Can start running. Compared with the asynchronous starting permanent magnet motor, the asynchronous starting synchronous reluctance motor does not use rare earth permanent magnet materials, and there is no problem of demagnetization. The motor has low cost and good reliability. [0003] In the existing technology, such as figure 1 As shown, the patent with the publicati...
