三相电动制动电机
Power Jacks 可为所有应用提供交流或直流电动机。
最常用的电机是三相交流感应电机，但我们也供应单相交流感应电机、伺服电机和直流永磁电机。
这些电机上的制动器主要设计用于保持制动。它们是弹簧加载的电释放装置（通电释放），具有故障安全运行特性，因此在供电中断或失效时，制动器将接合并制动负载。

Benefits
The brake units are a single disc type mounted on the non-drive end-shield of the motor and can be either DC or AC types (DC is the standard type). They are spring applied electrically released units (energise to release), which provide fail to safe operating characteristics such that on interruption, or failure of power supply, the brake will engage and arrest the load.
