Abstract:
1. A three-phase magnetic generator having a rotor that has rare-earth magnets, and a stator that has three coil groups, the generator comprising: a terminal plate set fixed into a fitting through hole formed in an annular portion of a core of the stator, the core provided radially inside winding portions of the stator, around which the coil groups are wound, wherein the terminal plate set includes three substantially T-shaped terminal plates and a resin mold for fixing and holding the three terminal plates, each one of the terminal plates includes a transverse bar portion and a longitudinal bar portion, each one of the terminal plates includes a terminal of the transverse bar portion connected with a coil wire lead of a respective coil group and a terminal of the longitudinal bar portion connected with an output lead, the resin mold covers the three terminal plates except for the terminals and is formed with a fitting leg around the longitudinal bar portion, the fitting leg being press-fit into the fitting through hole, the terminal plate set is structured so that the terminal of the transverse bar portion is positioned near the coil wire lead on an axial end side of the rotor and the terminal of the longitudinal bar portion is positioned on the other axial end side of the rotor when the fitting leg is press-fit into the fitting through hole, and the coil groups are connected in a delta connection so that an electric angle phase difference substantially becomes 240°.
