  • Flow control device for a gas stream
    Patent number: 6499310
    Abstract: An airflow control device for air streams in a motor vehicle air-conditioning system includes an installation frame with pivotable lamellae (2) that are driven by an electric motor via a gear mechanism arranged on the outside of the frame. The gear mechanism comprises a plurality of cylindrical gearwheels (9 to 12) arranged one above the other, so as to be very narrow and such that the overall dimensions of the housing (5) for the gear mechanism do not exceed the width and height dimensions of the frame (1). This novel arrangement allows integration of the drive as a whole and minimizes the amount of space required.

  • Two-phase motor, particularly a time piece motor or a motor for driving the hand of a display
    Patent number: 6043574
    Abstract: A two-phase motor formed by a stator part excited by electric coils and a magnetized rotor. The rotor has N pairs of poles which are radially magnetized in alternate directions, N being equal to 3 or 5. The stator part has at least two W-shaped circuits comprising each an electric coil surrounding the central leg. The "W" circuits are so arranged that when one of the central legs faces a magnetic transition, the other central leg faces a magnetic pole. The polar opening outs of the legs of a "W" circuit are angularly spaced by .pi./4. The polar opening outs of the central legs of the two "W" circuits belonging to different phases are angularly spaced apart by an angle which is substantially equal to .pi./2.+-.k..pi./N, where N is the number of pairs of magnetic poles, that is 3 or 5, and k is equal to 0, 1 or 2.

  • Electromagnetic actuator magnetically locked into two or more stable positions
    Patent number: 6020804
    Abstract: An electromagnetic actuator has four positions which are stable in the absence of a current and moves rapidly between these positions when acted upon by a current. The actuator has a thin, rotatable magnet (3) with two pairs of magnetic poles transversally magnetised in alternate directions, and a stator member having four pole pieces (9-12, 34-37, 48-51) of developed length P, each with an excitation coil. Two consecutive poles of the thin magnet (3) are spaced by a distance d. The thin magnet (3) is movable in an airgap of width E. wherein the size ratio P:E and P:d is greater than 8. The invention is useful for driving a device such as a valve or a switch.
