Abstract
The present invention relates to a motor for driving a clockwork. A rotatably supported rotor 1 has diametrically opposite permanent-magnet poles. A multi-phase coil arrangement is furthermore present to produce a magnetic field which deflects the rotor 1 out of its instantaneous position as a function of control signals present in each case on the coils 3 and 4 of the coil arrangement. The coil arrangement has a plurality of coils 3 and 4 arranged at an equiangular distance apart, surrounding the rotor 1, which coils can be controlled one after the other by sine voltages which are staggered a given angle apart.
