Description

[0002] A reduction motor refers to an integration of a reducer and an electric motor (motor). This integration is also commonly called a gear motor or gear motor. In order to perform braking well during use, the reduction motor will be used in conjunction with a brake.

[0003] When the brake is in use, the electromagnetic force generated by the power supply can first separate the brake disc and the brake pad, thereby facilitating the operation of the reduction motor.

In the prior art, when the brake disc and the brake pad (brake pad) are in contact and friction braking, the friction between the two will generate vibration and high temperature, and the friction force under vibration, impact and high temperature will increase the wear of the brake disc and brake pad, increase the wear resistance, and thus reduce their service life.
