Latest Patents

Rainer Hemmann holds a patent for a control circuit for an electromotor. This invention features a pair of relay contacts that directly connect the electromotor to a battery when closed. One side of the relay coil controlling the contacts is connected to a battery when a thermostat responsive to engine temperature closes. The other side of the relay coil is connected to the battery through an electronic switch, which can be a thyristor or a transistor. These components are in a conductive state when the ignition switch is closed. Notably, the thyristor remains conductive for one operation following the opening of the ignition switch, while the transistor is conductive for a predetermined time period after the ignition switch is opened. This innovative design improves the efficiency and reliability of electromotor operations.
