Abstract

Power supply method for a monophased stepping motor for a time piece, adapted to furnish the motor with chopped voltage pulses of duration T6 which can vary as a function of the load conditions and as a function of the supply voltage of the motor, characterised in that each so-called chopped voltage pulse is composed of a sequence of partial voltage pulses of equal polarity and of constant duration T4, and in that the time intervals T5i separating the said partial voltage pulses can vary as a function of the load conditions and as a function of the supply voltage of the motor. The invention applies to motors for time pieces. <IMAGE>
