Control Techniques 075E3C205BACAA Rotary Servo Motor Unit

Module Feature

075E3C205BACAA (part number 075140) belongs to Unimotor FM series brushless AC servo motor manufactured by Control Techniques,designed for high-precision closed-loop motion control. It integrates 2000PPR incremental optical encoder to provide reliable real-time speed and position feedback. Built-in 24VDC electromagnetic holding brake locks the shaft securely when power loss occurs for vertical axis safety protection. Compact 75mm flange frame delivers excellent shock and vibration resistance,widely applied in packaging machinery,small cutting equipment,material handling and precision automation 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.
