Products Description
Control Techniques 075E3B400CFECA Rotary Servo Motor Unit

Module Feature
075E3B400CFECA belongs to Unimotor FM series brushless AC servo motor manufactured by Control Techniques, rated 0.75kW. It integrates 400PPR incremental optical encoder to provide reliable real-time speed and position feedback. Built-in 24VDC electromagnetic holding brake locks the shaft securely when power is cut for safety protection. Compact frame structure delivers excellent shock and vibration resistance, widely applied in small automation equipment, packaging machinery, material handling and precision servo motion systems.
Working principle
The stator winding generates rotating magnetic field to drive permanent magnet rotor rotation. The built-in incremental encoder continuously feeds speed and position signals back to servo drive to form closed-loop control. The electromagnetic holding brake engages automatically once power loss occurs to lock the shaft and prevent accidental movement of mechanical load.
