<P>PROBLEM TO BE SOLVED: To provide a wheel suitable for a saddle-ride type electric vehicle, in which while both a mechanical loss and an energy loss are reduced and an increased travel distance is obtained from a battery, without losing productivity. <P>SOLUTION: The wheel for the saddle-ride type electric vehicle includes: a rim part 12d that supports a tire; a hub part 12h arranged inside the rim part and configured to rotate on a rotational axis c of the wheel; a spoke part 12g connecting the rim part to the hub part; a stator core 52 and a coil 51 provided around the rotational axis C of the wheel and arranged inside a spoke connection part 12r of the hub part; a ferrite magnet 41 arranged inside the spoke connection part of the hub part and outside the stator core with respect to the radial direction of the wheel, the ferrite magnet being opposed to the stator core and configured to rotate together with the hub part, the spoke part, and the rim part on the rotational axis of the wheel; and a back yoke part 40 arranged inside the spoke connection part of the hub part and outside the ferrite magnet with respect to the radial direction of the wheel, the back yoke part supporting the ferrite magnet. <P>COPYRIGHT: (C)2013,JPO&INPIT |
