Patent number: 8601676Abstract: The insertion of electrically insulating paper from a continuous roll into slots of a stator created by outwardly projecting teeth is described herein. The insertion of the insulating paper is done by the insertion of prewound coils in the stator slots. The electrically insulating paper is not cut prior to its insertion in the slots, thereby completely covering the outer surface of the stator. The insertion systems and methods described herein are also optionally concerned with the insertion of interphase insulation paper between the different coils inserted in the stator slots and with the insertion of slot closing wedges.Type: GrantFiled: June 28, 2010Date of Patent: December 10, 2013Assignee: TM4 Inc.Inventors: Bruno Carpentier, Martin Houle, Stephane Poulin

Patent number: 7049725Abstract: 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.Type: GrantFiled: November 24, 2003Date of Patent: May 23, 2006Assignee: TM4 Inc.Inventors: Pierre Blouin, Stéphane Poulin
