Abstract
A phase-shifting current-variable asynchronous adjustable speed motor comprises an insulating shell (7), a rotor (1) and a stator (2-3). Two ends of the stator (3) or the stator (2) are provided with an annular end plate (8) and one side of the stator (3) or the stator (2) is provided with an actuator (4). The rotor (1) is provided with a magnetism isolating pad (5) which separates the rotor into two segments. Double magnetic fields of the invention cause the rotor current synthesis to have effect on the motor. Magnitude of the rotor synthesis induced current can be changed by adjusting angles of the two magnetic fields and then the adjustment of the rotation speed of the asynchronous motor can be realized. The motor can be widely used in the fields of power, chemical industry, machinery, mining, metallurgy, transportation and energy saving. The motor has the advantages of saving investment, high reliability and little maintenance work. Especially, the motor solves the difficulty of adjusting speed of present large-capacity and high-voltage asynchronous motors and is helpful to realize telemechanisation, automation and computerization.
