  • Method to control stops of an intermittently operating driving motor
    Patent number: 4929875
    Abstract: The invention concerns a method to control the stops of an intermittently operating electric motor. The motor current is measured at even intervals and a mean value is created from the measured values. An actual value is compared with said mean value and a signal is given to stop the motor if the actual value deviates from the mean value a predetermined amount. Each new measured value replaces the first measured value in the series.
