SQM56.564R1Z3 Siemens Damper Motor

Overview

The Siemens SQM56.564R1Z3 is a high-torque reversing actuator designed for the precise positioning of air and gas dampers, flow control valves, and butterfly valves. Engineered for industrial and commercial burner applications, this electromotive actuator provides reliable rotary motion and high modulating accuracy. It features a robust design with die-cast aluminum housing and a synchronous motor, making it ideal for systems requiring dependable performance and repeatability in HVAC and process heating environments.

Features

• High-precision modulating control with minimal backlash and drive shaft play limited to 0.3 degrees
• Integrated auto/manual selector switch and manual forward/reverse toggle for easy commissioning and adjustment
• Independent disengagement clutches for the drive shaft and cam drum to facilitate manual alignment
• Equipped with two limit switches and four internal auxiliary switches for versatile control sequences
• Field-reversible rotational direction (counterclockwise by default)
• Externally visible position indicator for quick status monitoring
• Low-hysteresis gearing for both the actuator and potentiometer to ensure consistent signal feedback
