Abstract
The present disclosure relates to a brake mechanism, a joint actuator and a robot. The brake mechanism includes a friction member configured to be fixed to a rotor of the motor, a brake member abutting against one side of the friction member, a pushing member abutting against the other side of the friction member and configured to provide an adjustable pushing force to the brake member, a locking mechanism configured to prevent the brake member from rotating according to a brake command.
Claims18
A brake mechanism for a motor, the brake mechanism comprising:
- a friction member configured to be fixed to a rotor of the motor;
- a brake member, the friction member abutting against one side of the brake member;
- a pushing member abutting against the other side of the brake member and configured to provide an adjustable pushing force to the brake member;
