Abstract: front page image
(EN) PROBLEM TO BE SOLVED: To improve the space factor of coil winding in a slot and an assembly machining property by precisely insulating a core from the coil winding with less number of parts as much as possible.

SOLUTION: The stator is equipped with an interlock core 1 where a plurality of magnetic pole pieces 2 having back yoke and teeth 201 and 202 are interlocked via a joint 7 while the magnetic pole pieces can be bent, an insulator 8 that has a teeth periphery wall 15 for covering a teeth wall surface 3 and a back yoke projection part 16, and a comb-teeth-shaped back yoke insulation sheet 18 where a teeth reception channel 21 for inserting the plurality of teeth 202 is formed and a plurality of back yoke wall surfaces 4 are covered. In this case, the back yoke insulation sheet 18 is engaged to a channel being formed between the back yoke projection 16 and the magnetic pole piece 2 for fixing.
