Methods for dynamo-electric machine insulation handling

Abstract

Methods and apparatus for insulating interior walls of lamination slots of dynamo-electric machine components are provided. The relative speeds and sequence of cutting, forming, and inserting a piece of insulation material into the slot of the lamination core of a dynamo-electric machine component may be determined by a central drive mechanism. The central driving mechanism may have a plurality of cams, rotating with a main shaft, to control the translations of cutting, forming and inserting members.

1 . A method for insulating interior walls of lamination slots of dynamo-electric machine components comprising: 
 cutting a strip of insulation material into a segment having a predetermined length;    forming the cut segment of insulation material into a predetermined shape;    inserting the formed segment of insulation material into the lamination slot; and    controlling the cutting, forming, and inserting with a central control device having a single shaft and a plurality of cams coupled to a longitudinal axis of the shaft.    
   
   
       2 . The method defined in  claim 1 , wherein the cutting comprises moving a cutting member.  
   
   
       3 . The method defined in  claim 1 , wherein the forming comprises moving of a forming member.  
   
   
       4 . The method defined in  claim 1 , wherein the inserting comprises moving of an inserting member.  
   
   
       5 . The method defined in  claim 1 , wherein: the controlling of the cutting is performed by a first plurality of cams; 
 the controlling of the forming is performed by a second plurality of cams; and    the controlling of the inserting is performed by third plurality of cams.    
   
   
       6 . The method defined in  claim 5 , wherein the controlling the cutting further comprises sufficiently contacting each cam of the first plurality of cams with a roller coupled to at least one arm of a first yoke.  
   
   
       7 . The method defined in  claim 6 , wherein the sufficiently contacting comprises minimizing the play between the rollers and the first plurality of cams.  
   
   
       8 . The method defined in  claim 5 , wherein the controlling the forming further comprises sufficiently contacting each cam of the second plurality of cams with a roller coupled to at least one arm of a second yoke.  
   
   
       9 . The method defined in  claim 8 , wherein the sufficiently contacting comprises minimizing the play between the rollers and the second plurality of cams.  
   
   
       10 . The method defined in  claim 5 , wherein the controlling the inserting further comprises sufficiently contacting each cam of the third plurality of cams with a roller coupled to at least one arm of a third yoke.  
   
   
       11 . The method defined in  claim 10 , wherein the sufficiently contacting comprises minimizing the play between the rollers and the third plurality of cams.  
   
   
       12 . The method defined in  claim 1 , wherein the controlling is centrally driven by rotating the shaft.  
   
   
       13 . The method defined in  claim 12 , further comprising transforming the rotation of the shaft to translate a cutting member to perform the cutting.  
   
   
       14 . The method defined in  claim 13 , wherein the translation of the cutting member is periodic.  
   
   
       15 . The method defined in  claim 12 , further comprising transforming the rotation of the shaft to translate a forming member to perform the forming.  
   
   
       16 . The method defined in  claim 15 , wherein the translation of the forming member is periodic.  
   
   
       17 . The method defined in  claim 12 , further comprising transforming the rotation of the main shaft to translate an inserting member to perform the inserting.  
   
   
       18 . The method defined in  claim 17 , wherein the translation of the inserting member is periodic.  
   
   
       19 . The method defined in  claim 1 , further comprising advancing to a state in preparation for insulating a next slot.
