摘要： A lens driving module for holding and moving a lens is provided, including a lens holder having an accommodating space, a driving coil, a plurality of first magnetic members having a longitudinal structure, a virtual plane, and a plurality of second magnetic members, wherein the lens is disposed in the accommodating space. The lens holder is disposed between the first magnetic members and between the second magnetic members. The driving coil is disposed on the lens holder and surrounds the accommodating space. The virtual plane is perpendicular to a longitudinal axis of the longitudinal structure. The projections of the driving coil and the first magnetic members on the virtual plane along the longitudinal axis of the longitudinal structure overlap each other. When a first current flows through the driving coil, the lens holder moves relative to the first and second magnetic members along a first direction.

摘要： An optical rotary joint communication apparatus for communicating between a rotor and a stator. Optical sources and detectors are arranged on both the rotor and the stator to provide bi-directional communication. As the rotor rotates, downlink detectors on the rotor sequentially communicate via line-of-sight optical channels with corresponding downlink receivers on the stator. Each downlink receiver is provided a curved mirror reflecting the downlink beam onto the downlink receiver when the rotation angle of the rotor is within a corresponding angle interval. When the rotation angle moves past the angle interval, the downlink beams transition to another mirror and another downlink receiver. The downlink beams are directed predominantly tangential to the rotor circumference. Adjacent downlink transmitters transmit redundant data, and transitions between downlink receivers are staggered for adjacent downlink transmitters to occur at non-overlapping rotation angles in order to prevent loss of data during transitions.

摘要： An electric machine (1) has a stator (2) with a stator body (3) and a stator winding (4) and a rotor (5) rotatably disposed with respect to the stator and having a rotor body (6) with a plurality of permanent magnets received therein. The rotor is disposed with an air gap (14) between the rotor body and the stator body and to make a magnetic flux to pass between the permanent magnets of the rotor body and stator poles of the stator body through this air gap. The machine further comprises at least one member (15, 16) or an agent of a material having a high magnetic permeability configured to be positioned with respect to the stator body (6) so as to reduce the magnetic flux (A) from the permanent magnets through said air gap.

摘要： Provided are an electric toothbrush and its drive motor, which comprises a U-shaped magnetic yoke, a rotary output component, a second magnetic yoke and four permanent magnets. The two support legs of the U-shaped yoke are respectively wound with coils, enabling the two leg end faces to generate alternating magnetic poles under the control of circuit. The four magnets are centrosymmetrically disposed about a rotatory central line, the first and the fourth magnet are of the same polarity, the second and the third magnet are of the same polarity; the first and the second magnet are of the opposite polarity, disposed corresponding to the first leg; the third and the fourth magnet are of the opposite polarity, disposed corresponding to the second leg. Under the control of circuit, the driving permanent magnets drive the second yoke and the rotary output component to reciprocatively rotate about the rotatory central line.
