  • Automotive dynamoelectric stator
    Patent number: 8686610
    Abstract: The present invention provides an automotive dynamoelectric stator that enables vibration resistance of a lead portion to be ensured and reductions in area of the lead portion and a coil end group that is exposed to a cooling airflow to be suppressed without increasing work or cost. In a dynamoelectric machine according to the present invention, first lead portions that connect a plurality of windings to configure phase windings are each led axially outward from a rear-end coil end group, and then disposed so as to extend parallel to an axially outer peripheral surface of the rear-end coil end group so as to cross at least one other first lead portion, and so as to be separated from the axially outer peripheral surface of the rear-end coil end group.
