Kromschroder Servomotor IC50-15W15E 74215228

The Kromschroder IC50-15W15E is a servomotor designed for precise rotary motion control within a 0 to 90 degree range. It operates on a 230 V supply at 50 Hz, delivering a torque of 15 Nm with a holding torque equal to the running torque. The unit features a three-point step signal control, a duty cycle of 100%, and a feedback potentiometer rated at 1 W. It is intended for use with the Kromschroder DKR butterfly valve to regulate hot air and flue gas flow. The device halts at its current position when power is disconnected and complies with directives 2014/35/EU and 2014/30/EU, as well as EN 60730:2011. Its protection class is IP, safety class is 1, and it has a storage temperature range of -20 to 40 °C.

When selecting a servomotor of this type, ensure the supply voltage, frequency, and control signal (three-point step) match the existing system. The torque rating must be sufficient for the valve or damper being operated, and the shaft coupling must fit the valve stem. Check the mounting dimensions and the angle of rotation required. The unit should be installed with proper cable glands and protection against condensation, as specified by the manufacturer.

Common failures in this type of servomotor include loss of torque or complete stoppage due to gear wear or motor burnout. If the motor fails, the valve may remain in its last position, causing uncontrolled flow. Check for correct supply voltage and signal continuity. Overheating or condensation can lead to electrical faults, so inspect for moisture ingress and ensure the ambient temperature is within limits.
