  • Method for setting a polyphase electric stepper motor
    Patent number: 6680597
    Abstract: A method for setting an electric motor, which includes, during a non-powering sequence of at least one of the motor phases, measuring on a predetermined time window, the induced voltage (Ti) in the non-powered phase and in comparing its mean value to a threshold value (Ts) to stop powering of the motor on the current sequence if the measured mean value is less than the threshold value.
