  • Patent number: 8823304
    Abstract: The invention relates to a method for providing a trigger signal in response to the commutation of a mechanically commutated electric motor (1). The method comprising the steps of providing a mechanically commutated electric motor (1), providing a power supply for said mechanically commutated electric motor via electrical supply leads (10, 11) from power supply circuitry, providing a filter (15) connected to said electrical supply leads (10, 11), detecting with said filter (15) a voltage spike occurring at commutation, outputting from said filter (15) said trigger signal.
    Type: Grant
    Filed: October 10, 2008
    Date of Patent: September 2, 2014
    Assignee: Ideassociates (IOM) Limited
    Inventors: Preben Bo Fich, Curt Michael Petersen Willadsen

  • Publication number: 20080246422
    Abstract: A method for controlling a mechanically commutated electric motor, wherein the rotational angle of the output of said motor is determined by means of detection of the change in back electromotive force, when the electric motor commutates, and wherein the power supply to the electric motor is halted after a predetermined number of detected commutations.
