Why a motor overheat and must to be properly ventilated?
The motor life is related of its insulation windings, regardless of the length of bearings (wear motor member). Heating is a consequence of the energy losses due to the transformation inside motor from electrical energy to mechanical energy. Heating developed by the energy losses is accumulated inside motor and bring out through ventilation. The steady state is reached when the quantity of heating produced by motor is the same of the quantity of heating gets rid of; in continuous service condition this happens in 3รท5 hours.
