Latest Patents

Stefan Pöhler holds a patent for a "Method for turning a three-phase current motor on again and electrical circuit for implementing the method." This invention addresses the challenge of restarting a three-phase alternating current motor after it has been disconnected from a supply voltage. The method utilizes the residual field voltage induced by the rotor's residual field. By recording the time progressions of both the residual field voltage and the supply voltage, Pöhler's method calculates the phase difference between the two voltages. A specific time point is determined when this phase difference falls below a predetermined maximum value. A switching command is then triggered to apply voltage at a calculated time interval, ensuring the motor reconnects to the supply voltage at the optimal moment.
