Abstract

The invention provides a synchronous reluctance motor rotor structure and a motor with the same. The synchronous reluctance motor rotor structure includes a rotor core which is provided with a plurality of slit slots. A filling slot is arranged at each of the two ends of each slit slot. Each filling slot has a first position near the d axis of the rotor core and a second position away from the d axis at the end near the edge of the rotor core. Each filling slot has a slot opening at the first position or at the second position. In the same pole of the rotor core, when one filling slot of two adjacent filling slots has a slot opening at the first position, the other filling slot has a slot opening at the second position. Thus, the q-axis flux can be further blocked without affecting the entry of the d-axis flux into the stator, the difference between the d-axis flux and the q-axis flux can be larger, greater reluctance torque can be generated, and the output and efficiency of the motorcan be increased. Moreover, the torque ripple of the motor is reduced, and the vibration noise of the motor is reduced.

Description

technical field [0001] The invention relates to the technical field of motor equipment, in particular to a synchronous reluctance motor rotor structure and a motor having the same. 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 demagnetization problem, the motor cost is low, and the reliability is good; compared with the asynchronous motor, the efficiency is high and the speed is constant. [0003] The traditional synchronou...
