SQM53.462R1Z3 Siemens Damper Motor

Overview

The Siemens SQM53.462R1Z3 is a high-precision reversing electromotive actuator designed to provide accurate rotary positioning for air and gas dampers, flow control valves, and butterfly valves in industrial and commercial burner applications. Part of the robust SQM5 series, this motor is engineered for durability and repeatability, featuring a synchronous motor and a modular design that allows for various control and feedback options. It is particularly well-suited for systems requiring precise modulating control of fuel and air ratios.

Features

• Reversing motor with adjustable cams for precise switching point settings
• Internal and external position indication for easy monitoring
• Disengageable drive shaft and camshaft for manual adjustment and commissioning
• Maintenance-free gearwheels and bearings for long-term reliability
• Impact-proof and heat-resistant plastic covers with a rugged die-cast aluminum housing
• Support for multiple field-exchangeable circuit boards and potentiometers
