SIEMENS Servo Motor SQN70.424B20
Optimizes fuel-and-air balance with millimeter-precise bidirectional damper positioning.
SIEMENS Servo Motor SQN70.424B20 is an industrial solution that maximizes energy efficiency through precise damper control. In addition, it operates at a nominal voltage of 230 V AC / 50 Hz, consuming 40 W for energy efficiency. Furthermore, an integrated feedback system enables real-time position adjustment.
This synchronous motor supports bidirectional movement, controlling dampers in both clockwise and counterclockwise directions. It performs reliably across a wide operating temperature range of -25°C to +60°C. Moreover, its IP54 protection class resists dust and splashes, therefore ensuring uninterrupted operation in harsh industrial environments. The disengageable gear train simplifies mounting and maintenance.
