Abstract
A stator coil has a first layer wound around a tooth portion of a stator core-sequentially from the radially outer side to the radially inner side of a stator, and is wound while a winding direction is reversed for each layer. If the outermost layer is denoted by n (n is an odd number equal to or greater than 3) and the final turn in each layer is denoted by m (m is equal to or greater than 2), the m-th turn in the n-th layer is wound on the radially outer side of the stator, the stator coil on the radially inner side is lane-changed on a shorter-side tooth portion, and a part of the stator coil on the radially outer side in the outermost layer is lane-changed on a longer-side tooth portion.
