DEVICE FOR THE INTERMITTENT OPERATION OF THE COOLING FAN OF THREE-PHASE INDUCTION MOTORS, CONTROLLED BY THE TEMPERATURE OF THE STATOR WINDING

摘要

The invention relates to a device that allows the intermittent operation of a cooling fan, with a mechanism that is controlled by the temperature of the stator, in order to reduce losses due to resistance and to improve the operating efficiency of industrial three-phase induction motors such as those that operate pumps, compressors, conveyors, fans, welding machines and punching machines, inter alia.
