Abstract:
A rotary electrical machine includes a rotational shaft supported by a housing for rotation about an axis, a rotor coupled with the rotational shaft, and a stator fixed to the housing and oriented to face the rotor. A rotor position changing mechanism moves the rotor in an axial direction of the rotational shaft using a portion of a torque transmitted between the rotational shaft and the rotor as a driving force. The rotor position changing mechanism controls the strength of the magnetic field between the rotor and the stator by moving the rotor toward or away from the stator.
Abstract:
An electrically-powered scooter including a front wheel, a rear wheel and a frame assembly. A handlebar assembly and a seat assembly are supported by the frame assembly. The frame assembly includes a left frame rail and a right frame rail spaced laterally from one another and extending between the handle bar assembly and the seat assembly. A battery support extends between the left and the right frame rails at a position intermediate the handle bar assembly and the seat assembly. A battery is supported by the battery support. In one arrangement, the battery support includes an enclosure defining a battery storage chamber. The enclosure includes a guide member configured to engage a guide recess of the battery to guide the battery into the battery storage chamber. In another arrangement, the battery may include a recharging port, an axis of which defines an oblique angle with an axis of the battery.
Abstract:
This invention provides a rotary electric machine with a high productivity/maintainability. Since the shaft portion 43 or the stepwise drawn portion is formed with a flat face 47 perpendicular to the rotational axis, when the magnetic poles 42 are bonded to the rotor 40, an accurate gap control can be achieved by applying a certain pressure to the magnetic poles with a jig or the like using the perpendicular flat face 47 as reference, or by controlling the distance from the perpendicular flat face 47.
