Application example

End cap insulation 

• diameter: up to 200 mm / 7.87 inch
• possible applications: use in motors
  with low production quantities and/or
  great variety in height 
• compensation of stack tolerance
  is not possible 
• benefits for the customer:
  - the same type of end cap can
    be used for different heights 
• disadvantage for the customer:
  - bad heat dissipation from winding
  - end cap and paper are not fixed
    and might move
