Abstract
A lead conductor penetrating portion that bring out lead conductors to the inner diameter side is formed in a winding holding portion of a clamp ring for holding a rotor winding that overhangs from a rotor core, and furthermore a stopper is formed in a lead portion on the inner diameter side of the lead conductor, and a centrifugal force-resistant member for holding a centrifugal force acting on the lead conductor is interposed between the stopper and the inner diameter side of the winding holding portion.
Claims12
An electric rotating machine comprising:
- a stator having a stator core and a stator winding;
- and
- a rotor, the rotor comprising:
- a rotor core that faces the stator core via a gap in a radial direction and is fixed to a rotary shaft;
- a rotor winding incorporated in the rotor core;
- a clamp ring having formed therein a pressurizing portion that pressurizes the rotor core in a stacking direction and a winding holding portion for holding the rotor winding that overhangs from the rotor core on a circumferential side of the pressurizing portion;
- and
- a lead conductor that is brought out to an inner diameter side from the rotor winding overhanging from the rotor core, wherein
- a lead conductor penetrating portion to bring out the lead conductor to the inner diameter side is formed in the winding holding portion,
- a stopper is formed in a lead portion on the inner diameter side of the lead conductor, and
- a centrifugal force-resistant member for holding a centrifugal force acting on the lead conductor is interposed between the stopper and the inner diameter side of the winding holding portion.
