Larry G. Seever has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Apparatus and method for efficiently powering a one-phase motor
    Patent number: 8937449
    Abstract: An apparatus and method for drastically increasing the efficiency of a single phase AC motor. A DC solid state driver is used to pulse a combination of the motor coil and a series capacitor. The coil/capacitor combination allows the motor to run near resonance (or a multiple of resonance). This results in a flywheel effect that only requires pulses at the proper time to keep it going. The solid state driver is powered by pulsed DC at around 150 volts peak and clocked at 60 Hz by a square wave timing circuit.

  • Three-phase generator for motor control
    Patent number: 8179168
    Abstract: A pulse generator that can generate pulses separated by 120 degrees phase on each of three separate phase output leads for use with a 3-phase motor power driver. These output pulses can be of any desired frequency and voltage. In a particular embodiment of the invention, the phase output pulses take a logic level of 0-12 volts (12 volts peak) with an adjustable frequency of around 250 Hz and a duty cycle of around 50%. This combination of parameters is ideal for driving a 3-phase motor in a vehicle application. Any combination of pulse width or duty cycle, output level and frequency is within the scope of the present invention.
