Abstract:
1. A rotating electrical machine, comprising: a rotor to which a plurality of magnetic poles are provided along its circumferential direction; a stator core constructed by laminating together a plurality of core plates, and having a cylinder portion and a plurality of teeth that extend outwards in the radial direction from the cylinder portion; and a stator coil received in a slot between the teeth; wherein each of the teeth comprises: a tooth body portion that extends radially outwards from the cylinder portion; and a pair of projecting end portions, provided at an end of the tooth body portion, that are in extended state so as to extend in radial direction before the stator coil is received in the slot, and that are in curved state in which they are bent around in circumferential direction after the stator coil is received in the slot; and wherein, in the curved state, vacant spaces are defined at the slot sides of each curved portion that communicates with the tooth body portion and the projecting end portion, respectively; and wherein, the stator coil is in a state where a coil wire is wound around a bobbin of insulating material and is fitted upon the tooth body portion.
