Abstract:
An electric machine includes a stator core defining slots and hairpins disposed in the slots. The hairpins are selectively joined at connections to form windings that include at least first and second radial layers. Each connection is disposed in one of the layers. The connections are staggered such that the connections of the first layer are circumferentially offset from the connections of the second layer to increase clearance for tooling that forms the connections.
