  • Starting an induction machine
    Patent number: 10819255
    Abstract: A method for starting an induction machine without residual flux includes: scanning a state of the induction machine with different stator frequencies by controlling a supply voltage applied to the induction machine; determining whether a slip value, being a difference between a rotor frequency and a stator frequency, is within a slip interval; and, when it has been determined that the slip value is in the slip interval, regulating the slip value towards zero and magnetising the machine to the required level.
    Type: Grant
    Filed: January 2, 2019
    Date of Patent: October 27, 2020
    Assignee: ABB Schweiz AG
    Inventors: Andrey Kalygin, Christian Stulz, Christof Gutscher, Marc Rauer, Mate Jelavic
