The present invention is a method and apparatus that allows the torque of an electric motor to be increased allowing the motor to be operated at higher speeds and at higher torque without raising the supply voltage, thus allowing for a wider dynamic range of speed and torque to be realized. This is accomplished by connecting one or more capacitors in series with each motor winding, and selectively activating the capacitors at higher speeds where the frequency of the motor resonates with that of the capacitor(s). Switching a capacitor into the circuit with the motor in a particular frequency range allows higher currents to flow through the motor windings resulting in higher torque.
