Abstract: A direct current (DC) motor controller includes first and second electrode terminals, a motor switch and a control unit. The first and second electrode terminals are connected to a DC electric power source, and cooperatively conduct DC electric current therefrom to the DC motor. The motor switch has first and second terminals. The first terminal is connected to a DC motor. The second terminal is connected to the second electrode terminal. The motor switch is switchable between a first state and a second state. The control unit is connected between the first and second electrode terminals, and controls the motor switch to switch between the first and second states.
