Patent number: 7145302Abstract: A method for driving a DC motor includes generating a first voltage pulse, based on a pre-determined speed input and duty cycle, and configured to generate motor current of reference current value sufficient to achieve a desired speed according to the speed input. Subsequent pulses of the voltage are generated to maintain the current substantially within a range of the reference current. Another method includes sensing and comparing motor current to reference current value and generating an error signal therebetween, which is integrated over time to generate an integrated current error, which is compared with a reference pulse. Thereafter generating applied voltage pulses configured to: switch at each instance of the integrated current error exceeding or becoming less than the reference pulse value; generate a motor current sufficient to achieve a desired speed according to a pre-determined speed input; and having substantially zero average variation from the reference current.Type: GrantFiled: April 6, 2004Date of Patent: December 5, 2006Assignee: General Electric CompanyInventors: Amit Raja Sanglikar, Herman Lucas Norbert Wiegman, Charles Michael Stephens, Sunit Kumar Saxena, Pradeep Vijayan, Ajit Wasant Kane
