SQM53.464R1A Siemens Damper Motor

Overview

The Siemens SQM53.464R1A is a high-precision reversing actuator designed for the accurate positioning of dampers, flow control valves, and butterfly valves. As part of the SQM5 series, this electromotive actuator is engineered for applications requiring a high degree of modulating accuracy and repeatability in industrial and commercial burner systems. It features a robust design capable of delivering significant torque and is specifically configured for counter-clockwise (CCW) operation with a 3/8-inch square shaft.

Features

• Reversing motor allows for flexible positioning and control of air and gas flow components
• Integrated auto/manual selector switch and manual forward/reverse toggle for easy adjustments and commissioning
• Externally visible position indicator provides immediate visual confirmation of shaft orientation
• Low hysteresis gearing system ensures precise control and reduces mechanical play
• Equipped with two limit switches and can accommodate up to four internal auxiliary switches for complex control sequences
• Disengagement clutches for the drive shaft and cam drum allow for manual adjustment without power
