Kromschroder Servomotor IC20-30W3E 88300076

The Kromschroder Servomotor IC20-30W3E (SKU 88300076) is an actuator designed for precise, controlled rotary movement within a 0 to 90 degree range. It operates on a 230 V supply voltage with a frequency range of 50-60 Hz and provides a torque of 3 Nm. The unit features a 100% duty cycle, voltage-free limit switches, and adjustable holding torque. It is part of a comprehensive system that can be paired with butterfly valves or linear flow control valves to adjust gas and air volumes. The device complies with EU directives 2014/35/EU and 2014/30/EU, and safety standard DIN EN 60730-1.

When selecting a replacement actuator of this type, ensure the supply voltage, frequency, torque, and control signal match the existing system. The actuator must be compatible with the valve or damper it operates, considering the mounting flange and shaft dimensions. Check the angle of rotation and running time to match the application requirements. The electrical connections should be verified for voltage-free limit switches and feedback potentiometer specifications.

Common failures include loss of rotation due to motor or gear wear, which may cause the valve to remain in one position. Electrical issues such as short circuits or open windings can lead to no movement or erratic operation. Limit switch failures may prevent proper end-of-travel signaling. Check for condensation or moisture ingress, which can damage internal components.
