Motortronics 12th Dec 2022
The Motortronics MWH Series Solid State Motor Winding Heater is designed to prevent condensation build-up by applying a low level current to the AC motor windings when the motor is in the “off” condition. Motor windings are susceptible to condensation formation each time the motor is stopped and the windings’ temperature drops below the dew point.
Over a period of time, this condensation buildup can degrade the insulation of the windings and cause a short circuit when the motor is started. The same problem can occur when motors are not operated for an extended period of time. This is especially true for damp and humid locations.
