Title:
INSULATING STRUCTURE FOR CONCENTRATED WINDING MOTOR
Document Type and Number:
WIPO Patent Application WO/2011/058853
Kind Code:
A1
Abstract:
A bobbin formed with a stator coil (30) having a stator winding (2) wound thereupon in a concentrated manner is inserted into a divided iron core (1). An insulating paper (100) covers three of the outer circumference surfaces of the stator coil (30); the inserted insulation part of the insulating paper (100) on the side of the rotor being inserted between flange section (2b) of the bobbin and the stator coil (30), and the inserted insulation part of the insulating paper (100) on the opposite side of the rotor being inserted between flange section (2c) of the bobbin and the divided iron core (1). Then, the insulating paper (100) is secured by sticking a tape (200) on the remaining outer circumference surface of the stator coil (30). As a consequence, the insulating properties of the concentrated winding motor are improved, and the man-hour required for work related to insulating is reduced.
