1. 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;
a locking mechanism configured to prevent the brake member from rotating according to a brake command; and
a fixing member;
wherein the friction member and the brake member are annular in shape;
wherein the friction member and the brake member are sleeved on the fixing member;
wherein the friction member is circumferentially fixed with respect to the fixing member; and
wherein the brake member is circumferentially slidable with respect to the fixing member;
wherein the friction member is provided with a plurality of grooves on a side surface thereof opposite to the brake member, the plurality of grooves extend radially on the friction member, and the plurality of the grooves are spaced apart in a circumferential direction of the friction member.
