    Abstract: The method includes applying to the coil (3) of the motor (2) driving pulses having alternately a first and a second polarity, supplying the coil (3) with a determined quantity of electric energy during each driving pulse, detecting, after each driving pulse, the rotation or non rotation of the rotor of the motor (2) in response to said driving pulse, and adjusting said determined quantity of electric energy as a function of said detection.In order to further reduce the quantity of electric energy consumed by the motor, the method is characterised in that the adjustment of the quantity of electric energy supplied to the coil (3) is effected separately for the driving pulses having the first polarity and for the driving pulses having the second polarity.

    Abstract: The method consists in subdividing each driving pulse into a certain number of elementary periods of the same duration, in calculating directly or indirectly, at each elementary period, the value of an effective chopping rate He such that He=n1/n2 where n1 is the number of elementary periods during which the coil of the motor was connected to an electric power source from the beginning of the driving pulse and n2 is the total number of these elementary periods from the beginning of the driving pulse, in comparing this effective chopping rate He to the desired chopping rate Hc and, according to whether He≦Hc or He>Hc, in connecting or not connecting the motor coil to the power source from the beginning of the following elementary period. The device includes the means necessary for implementing this method. This method and this device allow the number of distinct rates available for chopping the driving pulses to be increased in a much simpler way than with known methods and devices.
