He has made significant contributions to the field of electrical engineering, particularly in the development of control devices for reversible rotating electrical machines. With a total of 2 patents, his work has implications for both automotive and electrical applications.
Latest Patents
Westerholt's latest patents include a control device for a reversible rotating electrical machine. This invention relates to a control device that can operate in either alternator or motor mode. The device comprises a main battery, an electric network, and a unit for controlling and commanding an inverter and a rectifier bridge for selection in alternator mode or starter mode. The machine is powered by the inverter, which is connected to a start-up control unit that can provide a voltage greater than that of the main battery. In motor mode, the inverter connects to the positive terminal of the secondary voltage source, while in alternator mode, the rectifier bridge connects to the main battery.
Another significant patent is a method for controlling a polyphase and reversible rotating electrical machine for heat engine motor vehicles. This method allows the machine to operate as either an electrical generator or an electric motor. It features two modes corresponding to different speed/torque characteristic curves. The first mode, called starter mode, enables high torque for low speeds to start the heat engine. The second mode, known as auxiliary-motor mode, allows for operation at higher speeds and lower torques.
