His work focuses on enhancing the efficiency and functionality of electric motors through innovative control mechanisms.

Latest Patents

One of Whitford's latest patents is an "Electric power control system." This invention features an instantly variable constant current control that is interposed between a bank of batteries and a motor. The variable constant current control comprises a series pass transistor operating in a linear mode, which is controlled by a reference voltage from a potentiometer coupled to an accelerator pedal. The correction voltage from the series pass transistor circuit is proportional to the current. A linear operational amplifier compares the accelerator reference voltage and the current correction voltage, which in turn controls the 'on' resistance of the series pass transistor.

Another notable patent is the "Modular motor and control means and method." This arrangement involves electric motors that are coupled together both mechanically and electrically. It includes series pass elements and current sensing devices in the power circuits of the respective motors. Each current sensing device outputs a voltage proportional to its motor current, which is applied to a respective linear operational amplifier. This amplifier controls the equivalent resistance of the series pass element, thereby regulating the magnitude of motor current. A single reference voltage is applied to all the linear operational amplifiers, ensuring that similar motors transmit the same torque regardless of differences in internal impedance.
