摘要： The control circuit of a step by step micromotor for example diphased, wherein a magnetized rotor cooperates with two stator elements coupled each to a respective excitation electric coil (A, B), comprises only 6 power transistors (T1-T6). The coils (A and B) have each a common connection point hence making a set of three connexion terminals between the coils and the control circuit. The circuit allows the supply to each of the coils of current pulses of opposite polarity and to short circuit the coils in the intervals between the pulses. The simplification resulting from the elimination of two power transistors for the second coil leads to an important reduction of the room taken by the control circuit and the connection strips.

摘要： This control device is used in connection with a motor comprising a magnetic rotor and at least two magnetic stator circuits coupled with respective coils (b1, b2). A logic circuit (21) is arranged to alternatively feed drive pulses to both coils and to connect the coil which is not fed to a detection circuit (24, 25) the output of which is connected to the logic circuit in order to determine the duration of a feed pulse or to trigger a new feed pulse. This control device allows the current consumption of the motor as well as the locking torque to be reduced, since the servo control obtained insures the rotor positionning in case an important disturbance should occur.

摘要： A polyphased stepping motor for the direct driving of the second or minute pin in a clockwork. The motor comprises a disc shaped rotor (1) axially magnetised so as to have 2N alternating poles and at least two stator members (2, 3) each made by a magnetic circuit with gap and command coil (6, 7). The magnetic circuit is formed by one or two U-shaped members coupled with the said coil. The arrangement is such that the number of steps per command current period be 60m/N. The invention also applies to motors for quartz clocks.
