AC motor with built-in electromagnetic brake function that provides instant braking during power outages or emergency stops for safe stopping. Used in equipment where positioning accuracy and safe stopping are critical, such as manufacturing line conveyors, lifting devices, machine tool spindles, and robot arms. Unlike standard AC motors, a spring-type electromagnetic brake activates simultaneously with power disconnection to securely lock the rotating shaft. Ideal for vertical shaft applications, heavy load retention, and emergency safety requirements, with brake torque and response time being important specification criteria for selection.
