ABSTRACT:
A motor controller for a recreational vehicle (RV) heating system is disclosed. The motor controller regulates the amount of current supplied to an electrical motor in a blower of the heating system in response to the operating voltage and a signal from a microprocessor. The microprocessor operates a linear program in response to a cyclical signal provided at a reset terminal. The motor controller includes a locked rotor sensor which determines if the motor is turning. The motor controller utilizes a resistor as a voltage limiting means and a field effect transistor (FET) for bypassing the resistor. The microprocessor and motor controller provide a highly reliable and readily adaptable heating system which is not disadvantageously susceptible to variations in the supply voltage.
