Abstract
A dynamoelectric machine stator core for receiving a pre-formed stator winding includes a core body defining a cylindrical core main peripheral surface. A plurality of axially extending stator slots are circumferentially spaced in the core body. Each of the stator slots defines a slot first section extending radially from the slot base to a slot intermediate radial position and a slot second section extending radially from the slot intermediate radial position towards the core main peripheral surface. The slot first and second sections communicate with each other and are circumferentially offset relative to each other. The slot first and second sections are positioned, configured and sized to facilitate insertion therein of a corresponding conductor section of the stator winding with reduced needs for deforming the latter.
