Abstract
A braking magnetic clutch is composed of a driving wheel, a driven wheel, a stator, a brake and a control system. The driving wheel is made from magnetic conducting material or both permanent magnetic material and the magnetic conducting material and is linked with a power input shaft. The driven wheel consists of a magnetizer or the combination of the permanent magnetic material and the magnetic conducting material and a driven shaft. The stator consists of a coil, an end plate which is equipped with a bearing and an adapter cylinder which is linked with the end plate. The control system consists of a rectifier voltage regulator, a storage battery, a controller and a control node. The coil is engaged during the blackout and is separated during the power failure. And during the separation, the brake is controlled through the controller to brake the driven shaft, and the brake generates power when running. When the coil is disconnected, permanent magnetic force couples the driving wheel and the driven wheel. The braking magnetic clutch has the advantages of rapid operation, environmental protection, less maintenance and long service life and is especially applied to the working condition that a driven mechanism and a power source are usually combined and the separation is transient, such as being used as an automobile clutch. The braking magnetic clutch can also be used as a common clutch.
