Title: Jack R Morgan: Innovator in Motor Control Technology
Introduction
Jack R Morgan is a notable inventor based in Tempe, AZ (US). He has made significant contributions to the field of motor control technology, holding 2 patents that showcase his innovative spirit and technical expertise. His work primarily focuses on enhancing the efficiency and functionality of brushless DC motors.
Latest Patents
One of Jack's latest patents is for a "Brushless three phase direct current motor control circuit." This invention involves a driver circuit that is coupled to the stator windings of a brushless three-phase DC motor. The circuit responds to the open circuit back EMF voltage induced in the next stator winding to be energized as the permanent magnet rotor of the motor rotates. This design produces phase current drive to the stator winding in synchronization with the motor's operation. The driver circuit includes an increment drive circuit that supplies periodic switching command signals to produce phase current drive in each stator. A key feature of this invention is the ability to vary the frequency of the periodic switch command signals during the motor's starting phase, preventing the motor from locking and ensuring a smooth start.
Another significant patent is for a "Circuit for converting alternating current voltages to a constant." This AC-DC regulator circuit is designed to provide a constant magnitude, minimal ripple DC supply voltage in response to AC line voltages with varying peak amplitudes. The output voltage is regulated to prevent exceeding a predetermined value through a feedback circuit that employs a regenerative mode of operation. This regulation ensures a minimal ripple, constant magnitude supply voltage suitable for sensitive loads.
