Embodiment Construction

[0045] Next, embodiments of an axial gap type rotating electric machine according to the present invention will be described with reference to the drawings.

[0046] (first implementation)

[0047] figure 1 It is a side view of an electric motorcycle 1 as an example of a device equipped with an axial gap type rotating electric machine according to the first embodiment of the present invention.

[0048] Such as figure 1 As shown, the electric motorcycle 1 is equipped with a front pipe 2 at the upper part in front of its vehicle body, and in this front pipe, a steering shaft not shown in the figure for changing the direction of the vehicle body is passed through freely rotatably. On the upper end of the steering shaft, a handle support portion 3 for fixing a handle 3a is attached, and handles 4 are attached to both ends of the handle 3a. In addition, the right side not shown in the figure ( figure 1 The handle 6 on the inner side) constitutes a rotatable throttle control han...

Abstract

The present invention provides an axial gap type rotating electrical machine that suppresses the tilting of the rotor caused by the lack of teeth. The first and second points (P1) and (P2) on the magnet facing surfaces of the first and second teeth (61a1) and (61a2) on both sides of the notch (TW) in the plurality of teeth (61) respectively include ), and with respect to the midpoint (CP) between the first and second teeth (61a1) and (61a2), on the opposite side across the central axis (BO) of the bearing, located closest to the midpoint including the midpoint and the center The plane (S) of the third point (P3) on the magnet-opposing surface of the third tooth (61a3) of the plane (H) of the axis (BO) is inclined from a direction perpendicular to the center axis (BO) of the bearing.

Description

technical field [0001] The present invention relates to an axial gap type rotating electric machine. Background technique [0002] As rotating electric machines used for driving sources of electric motorcycles and other general electric motors, axial gap type rotating electric machines are attracting attention in addition to conventional radial gap type rotating electric machines. [0003] As such an axial gap type rotating electrical machine, for example, an axial gap type electric motor has a structure of a rotor yoke (rotor side yoke) and a stator yoke (stator side yoke) of a rotating shaft supported on its bearings. yokes) are opposed to each other, and their opposing surfaces are perpendicular to the rotation axis. At the same time, on the opposing surface of the yoke on the rotor side, for example, a circular (or annular) field magnet is arranged, and on the opposing surface on the stator side, along the radial direction (radial direction) relative to the rotation axi...
