Knoedler Electric Motor Repair

Complete Knoedler Motor Repair Services

Plastic extrusion machines require very specialized motors to provide optimal performance on a factory assembly line. One example of these specialized motors includes the Knoedler Gear Drive Motor. This gear drive motor is very unique because it runs on 4 motors and it can run the extruder on only 3 of the motors if one motor fails. Special attention is needed during the repair of the Knoedler gear drive motor in order to bring it back to OEM specifications.

Knoedler Gear Drive Electric Motor Winding Removal

All 4 stators are stripped using our MotorSafe Induction warming stripping method. The first step is to cut off all 4 winding heads. The winding heads are kept to preserve the winding data for the stators. After the winding heads are cut off, we use induction warming to gently warm up the stators one at a time. When the stator is up to temperature and the varnish is softened, we utilize a hydraulic puller to lift out each coil. In addition to the winding heads, we also keep one coil from each of the 3 phase groups for data collection. During our stripping method, the integrity of the frame, the laminations, and the water cooling features are maintained.

It’s always important to ask your electric motor repair specialized how they strip your motors. The industry standard calls for the use of the Burnout Inceneration oven. In this method, the gear box motor would be placed into a Burnout Oven which can reach temperatures of 600 degrees Fahrenheit or greater. When any motors are introduced to such high temperatures, the frame is in danger of distorting. For motors with a water cooling jacket, this can lead to unnecessary leaks. Furthermore, the high temperatures can deteriorate the insulation between the laminations causing hot spots.

Knoedler Gear Drive Electric Motor Rewinding

The Knoedler gear box motor requires metric wire for its windings. We keep metric wire in stock and utilize German winding machines in our rewind process. Using the proper wire and the computerized winding machines ensures that we meet factory specifications. After the winding process is completed, we varnish the windings to insulate and protect the winding. Check out more information on our varnishing process here: Advanced Varnishing
