Kromschroder Servomotor IC20-60W3E 88300077

The Kromschroder Servomotor IC20-60W3E (SKU 88300077) is an actuator designed for precise rotary movement between 0 and 90 degrees. It operates on a supply voltage of 230 V with a frequency range of 50-60 Hz, delivering a torque of 3 Nm. The unit has a duty cycle of 100%, a safety class of 1, and a weight of 1980 g. It features a feedback potentiometer with a power rating of 0.5 W and accepts cables with a cross-section up to 4 mm2. The storage temperature range is -20 to 40 °C, and condensation is not permitted.

When selecting a replacement actuator of this type, ensure the supply voltage, frequency, torque, and duty cycle match the original specifications. The mounting dimensions and shaft coupling must be compatible with the existing control element. Check the cable cross-section and line entrance type to ensure proper connection. The actuator's rotation angle and holding torque should also be verified against the application requirements.

Common failures in actuators of this kind include motor burnout due to overloading or voltage spikes, which may cause the actuator to stop responding or move erratically. Gear wear can lead to loss of torque or jamming, resulting in the actuator failing to reach the commanded position. Electrical issues such as faulty wiring or a damaged feedback potentiometer can cause incorrect position feedback, leading to unstable control. Check for visible damage, test the motor windings, and verify the potentiometer resistance to diagnose issues.
