Reluctance synchronous motor

Evolved with cage asynchronous motor, in order to enable the motor to asynchronous start torque, also has a cage-like cast aluminum rotor winding. The rotor is provided with a corresponding reaction trough with the stator poles (only a salient part of the role, no excitation winding and permanent magnets), used to generate reluctance synchronous torque. According to the different rotor structure of the reactor can be divided into inner reaction type rotors, external rotor and reactive response inside and outside-rotor, in which foreign reactive response of rotor slot to rotor-cylindrical, ranging from its straight axis and axis air gap. In response to having within the rotor grooves, the axial direction of magnetic flux, and reluctance to increase. Reaction-rotor rotor combining both inside and outside the structure, direct axis and axis vary greatly, so larger motor power. Reluctance synchronous motors are also divided into single-phase capacitor run, single-phase single-phase dual-value capacitor capacitor start type, and many other types.
