A method and apparatus for controlling flux in an induction motor. During initial start of an induction motor drive the motor flux has to be charged up. The method provides time optimal flux forcing under limited inverter ampere capability. Command stator flux and current are generated and coordinated...http://www.google.com/patents/US6552508?utm_source=gb-gplus-sharePatent US6552508 - Apparatus and method for optimally controlling flux in an AC motor
