Latest Patents

Jerome's latest patents exemplify his expertise and forward-thinking approach. One notable patent is for a **control system for a permanent magnet motor**, where he successfully developed a method to accurately control the speed of a rotor in a two-winding permanent magnet motor. This system utilizes a dual-polarity pulse width modulation drive signal that compares the phase of the phase back electromotive force (emf) signal generated in the non-excited winding against a command signal. The outcome of this comparison is essential for varying the duty cycle of the drive signal, ultimately enhancing motor performance.

Another significant innovation from Sears is the patent for **initialization damping for a permanent magnet motor**. This invention addresses the challenges faced during the initialization phase of a gyroscope rotor. By applying an alignment pulse to ensure correct rotational direction upon startup, he also tackles the issue of rotor oscillation. His solution involves using the back emf signal to generate a feedback signal, which minimizes oscillation during alignment. By combining this inverted, frequency-multiplied signal with the alignment pulse, the rotor can achieve rapid alignment, thus improving efficiency in operation.
