ABSTRACT:
A security gate operating system, is disclosed which comprises an electrically powered motor; a thermally controlled circuit breaker set to remove power to the motor when the motor reaches a preselected threshold temperature; a cooling fan associated with the motor and selectively powered to provide auxiliary cooling to the motor to prevent the motor from overheating; and a cooling fan motor controller, adapted to selectively supply power to the cooling fan when the motor is approaching the threshold temperature. The apparatus can further comprise the cooling fan controller being a thermo-static switch set to close at a preselected temperature below the threshold temperature, or a programmed microprocessor/microcontroller programmed to provide power to the cooling fan at a preselected temperature below the threshold temperature or when the temperature of the motor is about to reach the preselected temperature.
