摘要： A magnet (10) that is an annular member is fixed or secured on an outer circumference surface or an inner circumference surface of a yoke (4) that is a cylindrical member. An lower end surface in the axial direction of the magnet is fixed or secured to the same plane as a lower end surface in the axial direction of the yoke (4), or the lower end surface in the axial direction of the magnet is fixed or secured so as to protrude a little from the lower end surface in the axial direction of the yoke. An annular groove (4a) that is recessed outward in the radial direction or inward in the radial direction is formed on a part of the outer circumference surface or the inner circumference surface that is continuous to the yoke (4).

摘要： A stator core stack formed by laminating a plurality of straight cores having a core back, a tooth, and a linking part for linking the core backs. In the stator core stack, the linking portion is folded and deformed the linking portion so as to join an end surfaces of the straight core, and a core back outer peripheral portion is formed at the back side of the core back, and the diameter of the core back outer peripheral portion is formed same as or shorter than the diameter of the inner peripheral surface of the housing, and is disposed in the housing. A bar-like member is press-fitted in the axial direction between both the end surfaces of the straight core. In other example of motor, an engaging portion extending in the axial direction and projecting in the radial inward direction is formed in the inner peripheral surface of the housing, and the end surfaces of the straight core are engaged or fitted with the engaging portion.

The core back of the stator core in the motor has an arc shaped inner circumferential surface therein that is offset from the center thereof. The stator core is produced from a laminated body having a stator core, a chuck frame that is integral with and surrounds the stator core, and connector arms that connect the stator core and the chuck frame and integral therewith. After the windings are wound around the stator teeth, the stator core is cut from each connecting arm and the stator core is removed from the chuck frame.

摘要： In a motor and bearing structure for a motor, a shaft is rotatably mounted on a fixed support, and a radially-extending rotor is connected to the shaft and rotatable therewith. A ball bearing assembly having an inner race, an outer race, and at least one ball bearing seated between the inner and outer races, is mounted between the shaft and the support for rotating the shaft and rotor relative to the support. A stator is radially spaced relative to the rotor, and fixedly mounted relative to the rotatable shaft and rotor. An approximately arc-shaped preload magnet is fixedly mounted on the support, and is axially spaced adjacent to the rotor to magnetically attract the rotor in the axial direction of the shaft and, in turn, apply a preload to the ball bearing assembly to prevent vibrations, wobbling or other rotational instability of the rotor. A ring-like, oil-impregnated bearing also rotatably supports the rotor and the shaft to further enhance the rotational stability of the rotor. The oil-impregnated bearing slidably contacts either (i) the outer race of the ball bearing assembly for rotating with the shaft and rotor relative to the outer race, or (ii) the inner race of the ball bearing assembly for rotating with the shaft and rotor relative to the inner race.
