Kromschroder Servo motor IC50-60W30TR10 74215215

The Kromschroder IC50-60W30TR10 is a servo motor (actuator) designed for precise rotary motion control within a 0-90 degree range. It operates on a 230 V supply voltage and 50-60 Hz frequency, delivering a torque of 30 Nm. The actuator uses three-point step control and includes a feedback potentiometer with a resistance of 1 kOhm and a maximum power of 1 W. It has a duty cycle of 100%, a protection class of IP, and a safety class of I. The device weighs 2300 g and is compatible with the Kromschroder DKR butterfly valve for regulating hot air and flue gas flow.

When selecting a servo motor of this type, ensure the supply voltage, frequency, torque, and control signal (three-point step) match the system requirements. The mounting dimensions and shaft coupling must be compatible with the valve or damper being actuated. The angle of rotation (typically adjustable up to 90 degrees) and the feedback potentiometer resistance (e.g., 1 kOhm) must align with the controller's specifications. Installation involves connecting the three-point step signal to terminals 1 and 2, using cables with a cross-section up to 2.5 mm2, and routing them through the provided M20 cable glands.

Common failures of such actuators include motor burnout due to overvoltage or prolonged stalling, potentiometer wear causing erratic feedback, and gear wear leading to reduced torque or jamming. Symptoms may include the actuator not moving, moving intermittently, or failing to hold position when power is disconnected. Check the supply voltage, wiring connections, and the feedback potentiometer's resistance and wiper current to diagnose issues.
