Abstract

The invention is an asynchronous starting magnetic resistance synchronous electromotor, which relates to a magnetic resistance synchronous electromotor, including a stator component, and a rotor part. The magnetic resistance synchronous electromotor adopts a claw pole part to generate a stator rotating magnetic field, a squirrel cage guide cuts the magnetic wire of the stator rotating magnetic field to generate an asynchronous starting rotational distance, leading the rotor part to a synchronous rotating speed. The rotor salient pole of the rotor part and the stator rotating magnetic field work mutually to generate a synchronous rotational distance of magnetic resistance nature. Two stator winding group is an integrated winding group, the fabricating automation degree is high, and the cost of human work is low. The magnetic resistance synchronous electromotor can start asynchronously, has the advantages of high motor efficiency and low cost, and satisfies the requirements of small power synchronous electromotor for energy saving electromotor.

Description

technical field [0001] The invention relates to an asynchronous starting reluctance synchronous motor, which relates to a reluctance synchronous motor, in particular to a reluctance synchronous motor which adopts a centralized stator winding and can start asynchronously. Background technique [0002] The reluctance motor is a low-power synchronous motor that generates torque by using the uneven reluctance of the rotor, also known as a reactive synchronous motor. The reluctance motor does not rely on the interaction of the magnetic field generated by the stator winding and the rotor winding to generate torque, but relies on the "minimum reluctance principle" to generate torque. Ordinary reluctance motors cannot start automatically, and there are squirrel cages on the rotor parts of ordinary asynchronous reluctance synchronous motors, and distributed stator windings are still used to generate stator rotating magnetic fields. The degree of automation in the assembly process of...
