In general, brake devices that provide braking force to the rotating shaft are largely mechanical and electric brakes.

Mechanical brakes use frictional forces generated when pressing the brake pads to a brake disc or brake drum, and vacuum, compressed air or hydraulic pressure is used as a means for this pressing. However, such a mechanical brake generates heat during braking, and the brake operation performance is changed by wear of mechanical components, and there are disadvantages of environmental pollution due to scattering of friction material wear dust.

In addition, in the case of a hydraulic type mainly used in a passenger car, a braking force may be remarkably lowered due to vapor lock phenomenon due to a high temperature of hydraulic oil during continuous braking for a long time.

On the other hand, the electric brake is a method of braking by using a generator or dynamo connected to the rotating shaft, and when braking, it is possible to convert some of the kinetic energy into electrical energy to recover, but the configuration is complicated and separate drive circuit There is a problem that it is necessary.
