Abstract
A brake assembly includes: a motor rotor; a brake disc fixed on the motor rotor; a friction plate fixed to and surrounding the brake disc; a bearing rotatably sleeved on the motor rotor; an electromagnet assembly fixed on the bearing; a baffle plate fixed to the electromagnet assembly; an armature slidably sleeved on the motor rotor, and located between the baffle plate and the electromagnet assembly; and a spring assembly provided between the armature and the electromagnet assembly. When the electromagnet assembly is de-energized, the armature is pushed by the spring assembly to move in a direction close to the baffle plate, such that the friction plate is clamped by the armature and the baffle plate to realize braking.
