AXIAL AIR-GAP ROTARY ELECTRIC MACHINE

摘要

The present invention provides an axial air-gap rotary electric machine (1) that is provided with: a stator (19) in which a plurality of core members (20), which have an iron core (21), a coil (22) that is wound around the outer periphery of the iron core, and a bobbin (23) that is disposed between the iron core and the coil, are arranged in a circular shape centred around a rotational axis (A); and at least one rotor (30) that faces an end surface of the iron core with a prescribed air gap therebetween in the radial direction of the rotational axis. Therein, the bobbin (23) has a cylinder portion (23a) into which the iron core is inserted, and a flange portion (23b) that extends for a prescribed length around the outer periphery of the cylinder portion (23a) and in a vertical direction, and the coil (22) is wound around the outer periphery of the cylinder portion (23a) by regular winding, and is formed by a sequence of layers wherein the number of turns for each layer wound further to the outside than the layer that is wound so as to be in contact with the flange portion (23b) is at least one less than the number of turns in the adjoining inner layer.
