摘要： A motor drive unit for driving a direct current electric motor including a moving part equipped with permanent magnets. The motor drive unit, which is powered by a voltage supply source, includes a switch circuit, an inductor circuit and a capacitor circuit including a set of capacitors. By selectively opening and closing the switches of the switch circuit, a series of consecutive low energy pulses can be generated such that the power consumption of the motor drive circuit is minimized.

摘要： A DC motor including a continuous rotation rotor; a first inductor characterized by first parameters; a second inductor characterized by second parameters; a voltage supply unit; a measurement unit for detecting time instants when a first induced voltage in the first inductor equals a second induced voltage in the second inductor; and a control unit for controlling the application of drive voltage pulses to the inductors. The rotor faces first the second inductor before facing the first inductor when being rotated. At least one of the second parameters is selected different from a corresponding parameter of the first parameters such that a maximum induced voltage in the first inductor is greater than a maximum induced voltage in the second inductor. The control unit is arranged to trigger each of the drive voltage pulses after a detection of an equal induced voltage in the first and second inductors.

摘要： The invention concerns a method for controlling a continuous rotation miniature motor including a rotor carrying permanent magnets and a stator carrying at least one coil in which an alternating induced voltage is generated when the rotor rotates, this method consisting in maintaining the rotation of said rotor by successive pulses (102) supplied, in respective half periods of the induced voltage (U.sub.i), before the induced voltage reaches a maximum absolute value in each of these half periods. In particular, the time interval (t.sub.1) between a passage through zero of the induced voltage and the beginning of a maintenance pulse (102), provided in the half period following said passage through zero, is constant.

摘要： A synchronous motor device for a timepiece including a synchronous motor for the timepiece having a rotor with a pair of magnetized rotor poles around its circumference, a stator consisting of a pair of stator plates with a plurality of stator poles arranged around the vicinity of said rotor separated by an air gap, and an energizing coil supplying alternating magnetic flux to said stator.The synchronous motor for timepiece includes main stator poles, first supplementary stator poles and second supplementary stator poles.The main stator poles are further provided with both of the stator plates at the facing position against the rotor shaft and mainly forms the static stable position of the rotor. The first supplementary stator poles are facingly positioned against the rotor shaft and provided with both of the stator plates at separate positions from said main stator poles. This first supplmentary stator poles form the dynamic stable position of the rotor in the cooperation with the main stator poles and have wider gaps than the main stator poles. The second supplementary stator poles are facingly positioned against the rotor shaft and provided in the vicinity of the dynamic stable position of the rotor in order to place the predetermined braking force on the rotor which rotates over the dynamic stable position. This second supplementary stator poles have wider air gaps than the main stator poles and the first supplementary stator poles. Consequently the synchronous motor can achieve the properties of smooth self-starting rotation.

摘要： In order to obtain very long operating autonomy without maintenance, with low power consumption and low wear and tear, both the energizing and de-energizing of a DC motor are controlled by an electronic switching circuit providing bounce-free switching. A switching-on control circuit actuates the switching circuit, causing it to energize the motor. A switching-off control device, comprising a rotary component connected to the motor shaft and including contact elements responsive to the position of the rotary component, actuates the switching circuit to cut off the power supply to the motor after the rotary component has rotated through a predetermined angle. The arrangement is advantageous for driving apparatus which is not easily accessible and lacks reliable mains power. Another useful particularity consists in a multiple plug device whereby the rate of intermittent driving may be varied within the range of 1 day to 31 days.

摘要： A gear train mechanism for a wristwatch provides a thinner watch, the gear train comprising a frame plate, a dial, a plate interposed between the dial and the frame plate, and a shaft rotatably supporting a center wheel and pinion. The shaft is attached to the frame plate. Rubbing and misalignment of the hands is prevented by aligning their rotating support members for an extended longitudinal distance on the shaft. This is accomplished by the gear train of this invention despite a reduction in the thickness of the watch. Hour and minute hands or hour, minute, and second hands are provided in alternative embodiments.
