Space Heater for Motor
As the name itself indicate that it is used for heating purpose of motor or panel. In large electric motor or panels, if the motor is out of service then condensation form due to fluctuating temperature ,even in seal enclosure. This may result in electric components corrosion and insulation decrease. Such motor or panel used after long time then there is chance of damage in motor or panel due to insulation failure. The space heater keeps the internal temperature of the motor above the ambient dew point while the motor is OFF. The heater helps to prevent condensation from forming inside the motor which can be damaging to motor windings, bearings and electrical connections. Wire type space heater is used in motor or panel. This space heater is wound circular type on the winding, which is outside to the stator core. Below figure shows the assembly of space heater. It is very important to switch off the space heater whenever the motor is running or panel is operating condition.
