Title: The Innovative Contributions of Richard F. Schmerda
Introduction
Richard F. Schmerda is a notable inventor based in Oak Creek, Wisconsin, with a remarkable portfolio of nine patents. His work primarily focuses on advancements in motor control technology, showcasing his expertise in electrical engineering and innovation.
Latest Patents
One of Schmerda's latest patents is a DC motor speed controller designed to enhance the performance of battery-driven DC motors. This controller regulates the average motor current by utilizing a series-connected FET, which is switched on and off through a pulse-width-modulated gate signal. The motor speed is adjusted by varying the duty cycle of the signal generated by an oscillator. Additionally, the device incorporates an undervoltage protection circuit that monitors the battery voltage and compares it with a reference system featuring hysteresis. An overload protection circuit is also included, which senses the motor current, integrates the sensed signal, and compares the result with a Zener reference diode connected in an amplifier circuit for positive feedback. The outputs from the oscillator's pulse-width-modulated signal, the undervoltage protection circuit, and the overload protection circuit are fed into a 'NOR' logic gate, which ultimately drives the gate of the FET.
