Electromagnetic speed adjusting three-phase asynchronous motor

Abstract

The invention discloses an electromagnetic speed adjusting three-phase asynchronous motor. The electromagnetic speed adjusting three-phase asynchronous motor comprises a three-phase asynchronous motor body, an electromagnetic slip clutch and a speed adjusting controller, wherein the three-phase asynchronous motor body is connected with the electromagnetic slip clutch; the electromagnetic slip clutch is provided with the speed adjusting controller; the three-phase asynchronous motor body is supplied with power through an AC380V three-phase asynchronous motor power source; the speed adjusting controller is supplied with power through an AC220V speed adjusting controller power source. A clutch coil can be protected, and leakage accidents and electric shock accidents are effectively prevented.

Description

technical field [0001] The invention relates to an electromagnetic speed-regulating motor, in particular to an electromagnetic speed-regulating three-phase asynchronous motor. Background technique [0002] Electromagnetic speed regulating motor is also called slip speed regulating motor, also known as electromagnetic clutch. The electromagnetic speed regulating motor has two shafts, one of which is connected to the prime mover, and the other is connected to the drag object. By adjusting the voltage of the electromagnetic speed regulating motor, the output speed is lower than the input speed. Its working principle is to adjust the electromagnetic speed regulating motor. The slip rate of the high-speed motor is used to change the output speed. [0003] The electromagnetic speed control motor relies on the speed control controller to adjust the speed of its output shaft. The existing electromagnetic speed-regulating motor generally adopts two power supplies, one 380V power su...

Problems solved by technology

During use, the user only disconnects the power supply of the motor when not using the equipment, but does not disconnect the power supply of the speed controller, which will cause the armature connected to the output shaft of the motor to be damaged after the motor is powered off. Stop rotating, but the clutch coil is still rotating, the voltage on the clutch coil will increase, the current in the coil will increase, and the speed control controller is in this abnormal working state. Long-term operation will burn out the magnetic coil, resulting in speed regulation controller not working
