Description
Technical Field
The invention relates to the technical field of motors, in particular to a reluctance motor and a working method thereof.
Background
Reluctance motors are motors that use the variation of the reluctance of the air gap between the stator and the rotor to produce torque, based on the "reluctance minima principle", the magnetic flux must be closed along a path of least reluctance, and when the rotor axis and the stator axis do not coincide, reluctance forces act on the rotor and tend to be in a position of least reluctance. Salient poles of stator and rotor of the traditional reluctance motor are formed by laminating common silicon steel sheets, so that eddy current and hysteresis loss of the motor are reduced as much as possible. Concentrated windings are wound on the salient poles of the stator, no windings are wound on the salient poles of the rotor, an alternating-current magnetic field is formed at an air gap after alternating current is supplied to the windings, the magnetic field flows from the stator to the rotor and then flows back to the stator to form a loop, and the loop always flows through a path with minimum magnetic resistance.
During assembly, the multi-layer rotor core is sleeved on the outer wall of the rotating shaft, and an operator can cause more or less rotor cores by using a traditional assembly method, so that the performance of the reluctance motor can be affected. Moreover, after the rotor core is assembled, the support needs to clamp the outer wall of the rotor core during storage and transportation, and the outer wall of the rotor core is damaged due to improper operation.
