SQM53.582A2 Siemens Damper Motor

Overview

The Siemens SQM53.582A2 is a high-precision electromotive reversing actuator designed for the accurate positioning of air and gas dampers, flow control valves, and butterfly valves. As a critical component in industrial and commercial burner systems, this actuator is engineered for use with burner controls and can be integrated into high-demand HVAC and process heating applications. It features a robust die-cast aluminum housing and a synchronous motor that ensures reliable, repeatable performance. The SQM53 series is particularly noted for its modulating accuracy and the ability to disengage the drive and camshafts for manual adjustment.

Features

• Reversible synchronous motor with locking-proof protection
• Internal and external position indication for easy monitoring
• Separately adjustable drive shaft and camshaft independent of the gear train
• Manual disengagement of the shaft from the gear and motor via a coupling pin
• Eight easily accessible internal auxiliary switches for complex control sequences
• Durable construction with die-cast aluminum housing and impact-resistant plastic covers
• Maintenance-free gearwheels and bearings for long-term service life
• Integrated auto/manual switch for simplified setup and adjustments
