摘要： An electric motor includes a housing that receives multiple magnets that are circumferentially arranged in the housing. A resilient member has two inserted portions that are respectively inserted into gaps formed among the magnets. For example, four inserted portions of the two resilient members are respectively inserted into four gaps formed among four magnets, so that the inserted portions are resiliently deformed in the gaps. The inserted portions apply force to the magnets such that the magnets are circumferentially spaced from each other. Thus, the four magnets are urged onto an inner wall of the housing by the two resilient members. As a result, movement of the magnets is restricted in both of the circumferential direction and the axial direction of the housing. Therefore, the magnets can be maintained in the housing using a simple structure without increasing the number of components.

摘要： A multi-layer coil is wound around a bobbin having a center pillar and a small and a large flanges connected to longitudinal ends of the center pillar. A winding space having a trapezoidal cross-section in a plane cut through the center axis of the bobbin is formed outside the center pillar between both flanges. To wind the multi-layer coil in this winding space, a turning position where a layer of the coil moves up to a higher layer is set by a position setter, and the turning position is automatically shifted layer by layer to form a sloped outer surface of the coil. The coil is wound in a shape fitting the trapezoidal winding space without reducing the winding speed. The space factor of the coil in the winding space is improved, making the coil compact in size.

摘要： A brushless motor composed of a cylindrical stator and a magnet rotor rotatably supported in the stator is driven by a battery. The stator includes a multi-phase armature winding to which current is supplied from the battery through a drive-control circuit. The drive-control circuit includes switching elements that are selectively turned on and off to generate a rotating magnetic field in the stator. The switch-timing of the switching elements is controlled according to a rotational position of the rotor and the battery voltage. When the battery voltage is normal, the switch-timing is set to an optimum point so that a maximum efficiency of the brushless motor is obtained. When the battery voltage becomes low, the switch-timing is advanced to secure a required motor speed. Thus, the required motor speed is always secured without using additional devices such as a voltage stabilizer or a pulse-width modulation controller.
