Title: The Innovations of Theodore M Heinrich: A Pioneer in Motor and Inverter Technologies
Introduction: Theodore M Heinrich is a notable inventor based in Murrysville, Pennsylvania, with an impressive portfolio of 21 patents to his name. His work primarily focuses on innovations in synchronous motor starting and battery-powered vehicle drive technologies, showcasing a significant contribution to the field of electrical engineering.
Latest Patents: Among his latest patents, Heinrich developed a "Converter for Synchronous Motor Starting." This invention involves a system that rectifies the input voltage from a polyphase power source to generate a starting current with a notable DC component. The innovative approach entails sequentially applying this starting current to each phase winding of the synchronous motor, allowing the motor’s angular velocity to increase synchronously with the frequency of the current application. The invention cleverly enables forced commutation until the motor achieves synchronization with the input power source, at which point the system switches to natural commutation mode.
Another significant invention is the "Reconfigurable Inverter Apparatus for Battery-Powered Vehicle Drive." This inverter apparatus is designed to operate in two modes—normal drive and battery-charging. In the drive mode, it inverts DC power from on-board batteries to polyphase AC for powering the vehicle drive motor. Conversely, in battery-charging mode, it effectively draws current from an external energy supply to recharge the batteries. This innovative design accommodates energy sources with varying voltages and frequencies, making it highly versatile for use in electric vehicles.
Career Highlights: Throughout his career, Heinrich has been associated with prominent companies, including Westinghouse Electric Corporation and White-Westinghouse Corporation. His work at these institutions allowed him to refine his expertise in electric motor technology and inverter systems, paving the way for the groundbreaking inventions he later developed.
Collaborations: During his professional journey, Heinrich has collaborated with a variety of talented colleagues, including Colin D Schauder and Robert M Oates. These collaborations have further enhanced his innovative capabilities, contributing to the successful development of numerous patents.
Conclusion: Theodore M Heinrich's contributions to the fields of synchronous motors and inverter technology highlight his role as a significant innovator in electrical engineering. With his multiple patents, he continues to inspire future generations of inventors and engineers, solidifying his legacy in the realm of innovation.
