The invention relates to a motor controller, and discloses a brake assembly. The brake assembly comprises a brake disc, brake electromagnets, armatures and a brake releasing retaining device, whereinthe brake electromagnets are connected with a motor cover; brake springs used for pushing the armatures to be far away from the brake electromagnets are arranged between the brake electromagnets and the armatures; the brake disc is fixed on a motor shaft and is arranged on the other side of each armature; the brake releasing retaining device is independently connected with the brake electromagnetsand the armatures and comprises a rotatable opening and closing travel driving element; and therefore, through electric control and mechanical control, the integrated functions, including electric control, electric releasing, manual releasing and releasing retaining, of a brake can be realized. In addition, the invention also discloses a rotation motor and a crane. During outage, the brake assembly does not need to disassemble a whole brake for braking or releasing braking, and also does not need other special tools for braking or releasing braking, and a braking and braking releasing processis simple and quick.

    本发明涉及电机控制器,公开了一种制动器总成,包括制动盘、制动电磁铁、衔铁和制动释放保持装置,制动电磁铁与电机盖相连,且制动电磁铁和衔铁之间设有用于推动衔铁远离制动电磁铁的制动弹簧,制动盘固定在电机轴上,且设置在衔铁另一侧,制动释放保持装置分别与制动电磁铁和衔铁连接,且该制动释放保持装置包括转动式开闭行程驱动件,以能够通过电控制和机械控制实现所制动器的电动制动、手动制动、电动释放、手动释放及其释放保持的集成功能。此外,本发明还公开一种回转电机和起重机。本发明的制动器总成在断电时不需要拆除整个制动器来制动或释放制动,也不需要其它专用工具制动或释放制动,使制动和释放制动的过程更为简单快捷。
