Abstract

The invention provides a synchronous reluctance motor rotor structure, a motor and a manufacturing method of the rotor structure. The synchronous reluctance motor rotor structure comprises a rotor core which is provided with multiple slit slots, two ends of each of the slit slots are provided with two filling grooves to form a magnetic barrier layer, a first end of each of the filling grooves is adjacent to a slit slot, a second end of each of the filling grooves extends in the radial direction of the rotor core, and the outer peripheral surface of the rotor core is provided with a notch communicating with an end of the second end each of the filling grooves. By setting notches and bevels at the ends of the filling grooves, the reluctance torque of the motor can be increased, the torque ripples generated by a rotor and a stator tooth space can be weakened by each other, the purpose of reducing the torque ripple of the motor is achieved, the vibration noise of the motor is reduced, theefficiency of the motor with the rotor structure is improved, and the starting ability of the motor is improved.

Description

technical field [0001] The invention relates to the technical field of motor equipment, in particular to a synchronous reluctance motor rotor structure, a method for manufacturing the motor and the rotor structure. Background technique [0002] The direct 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 reluctance torque is generated by the rotor inductance gap to realize the constant speed operation. It can be directly connected to the power supply to realize the start operation. . Compared with the direct-start permanent magnet motor, the direct-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. Compared with asynchronous motors, it has high efficiency and constant speed. The direct-sta...
