Abstract
A stator structure is provided with a stator core having a plurality of cooling passages or slots and an annular resin layer formed on an inner peripheral surface of the stator core that defines a rotor receiving opening. The stator core has a plurality of protrusions disposed on the inner peripheral surface of the stator core to control the depth of the annular resin layer formed on the inner peripheral surface of the stator core. The protrusions have radial thicknesses that are substantially equal to the radial thickness of the annular resin layer.
