<p>PURPOSE: To ensure an insulation distance between a laminated core and a winding by folding an insulation sheet at the opposite end parts thereof and stopping the folded parts to a coil cover. CONSTITUTION: An insulation distance L1 is ensured between a laminated core 1 and a winding 2 wound around the core 1 by means of an insulation sheet 3 wound around the winding 2. The winding exposed to the opposite end laces of the laminated core 1 is covered, at the opposite end parts 21 thereof, with an insulating coil cover 4. The coil cover 4 is provided with an insertion piece 41 being fitted to the inside of the winding 2 thus securing the winding 2 and folded parts 31, provided at the opposite ends of the insulation sheet 3, are stopped at the insertion piece 41. This structure ensures a sufficient insulation distance between the laminated core and the winding.</p> |
