  • Electrical controller for machines
    Patent number: 9787228
    Abstract: An electrical controller for electric rotating machines is provided. A control system for electric rotating machines transmits a controlled quantity of current to or from different windings of the electric rotating machine at any given time. Furthermore, the amplitude of the current is independently variable of the timing and duration of the transmission of the current to or from the windings. This allows increased control of the electric rotating machine and facilitates the operation of the electric motor at high mechanical and/or electrical speeds.
    Type: Grant
    Filed: April 27, 2015
    Date of Patent: October 10, 2017
    Assignee: Aeristech Control Technologies Limited
    Inventors: Bryn Geoffrey Roddick Richards, Wenshan Hu

  • Controller for improving control and operation of AC motors
    Patent number: 9041328
    Abstract: An electrical controller for electric motors is provided. A control system for an electric motor comprises a supply for supplying excitation current to different windings of the motor at any given time. Furthermore, the amplitude of the excitation current is independently variable of the timing and duration of the application of the excitation current to the windings. This allows increased control of the motor and facilitates the operation of the motor at high mechanical and/or electrical speeds.
