Electromagnetic brake assembly and lifter

According to the electromagnetic brake assembly and the lifter, when the lifter breaks down or is powered off, the brake disc can press the rotor on the output end of the motor to conduct braking, the electromagnetic brake locks the motor, locking of the rotor by the brake disc is relieved by manually operating the rotating rod, and normal work of the lifter is achieved. And people and the like which are parked in the air due to faults are safely transferred. According to the electromagnetic brake assembly and the lifter provided by the utility model, the release of the brake can be realized in a relatively labor-saving manner, and the harm to a user caused by power failure or faults is reduced. 当升降器发生故障或断电时，刹车盘会压紧电机输出上转子进行制动，电磁制动器锁住电机，本实用新型公开了一种电磁刹车组件及升降器，通过手动操作转动杆解除刹车盘对转子的锁定，实现升降器正常工作，将因故障而停半空中的人员等安全转移。本实用新型提供的一种电磁刹车组件及升降器可以较为省力的实现刹车的解除，减少如断电或故障时给用户造成的危害。
