Kromschroder Servomotor IC20-15W3T 88300059

The Kromschroder IC20-15W3T is a three-point step control servomotor designed for precise rotary movement within a 0 to 90 degree range. It operates on a 230 V supply at 50-60 Hz, delivers a torque of 3 Nm, and has a duty cycle of 100%. The actuator features voltage-free limit switches and an adjustable holding torque equal to its torque. It is certified to 2014/35/EU, 2014/30/EU, and DIN EN 60730-1, with a safety class of 1. The device weighs 1950 g and has a storage temperature range of -20 to 40 °C.

When selecting a replacement actuator of this type, ensure the supply voltage, frequency, torque, and control type (three-point step) match the original. The mounting and shaft dimensions must be compatible with the valve or damper. Check the angle of rotation range and the cable gland size (M20) for proper connection. The feedback potentiometer resistance and power rating, if present, must match the control system.

Common failures include loss of torque, erratic movement, or complete stoppage due to worn gears or motor issues. The actuator may fail to hold position when power is disconnected, indicating a problem with the holding brake or gear train. Check for loose wiring, damaged limit switches, or condensation inside the housing, as moisture can cause electrical shorts.
