Abstract

An integrated switch reluctance type electromagnetic speed-adjustable motor comprises a machine shell, a machine base, an inner rotor shaft, an outer rotor shaft, a stator, an integrated switch reluctance type outer rotor, an air gap between the stator and the integrated switch reluctance type outer rotor, a switch reluctance type inner rotor, an air gap between the integrated switch reluctance type outer rotor and the switch reluctance type inner rotor, a slip ring, a brush, a position sensor, a bearing, a connection bearing, a bolt and a wire. The integrated switch reluctance type outer rotor comprises an outer layer cylindrical rotor, a middle layer magnetism isolation cylinder and an inner layer cylindrical salient pole armature. The switch reluctance type inner rotor comprises an inner rotor salient pole core and an inner rotor exciting winding. The motor has the advantages that integration of a traditional alternating-current motor and a switch reluctance motor is achieved, stepless speed adjustment is carried out, a frequency converter is replaced, and the motor can be applied to various speed-adjustable drive loads, is small in size, high in efficiency, low in cost, firm and durable and wide in speed adjustment range and is not limited by voltage and power levels.

Description

technical field [0001] The invention relates to an electromagnetic speed-regulating motor, in particular to an integrated switched reluctance electromagnetic speed-regulating motor, which can be widely used in various fields requiring speed-regulating drives. Background technique [0002] Electromagnetic speed-regulating motor (also known as slip motor) is composed of three-phase AC asynchronous motor, electromagnetic slip clutch and excitation current controller. Among them, the three-phase AC asynchronous motor is the prime mover of electromagnetic speed-regulating motor. The operation of the high-speed motor provides power, and the electromagnetic slip clutch provides different excitation currents through the excitation current controller to complete the speed regulation function. [0003] The three-phase AC asynchronous motor and the electromagnetic slip clutch of the traditional electromagnetic speed regulating motor are two independent parts, which are connected togeth...
