STATOR FOR ROTATING ELECTRICAL MACHINE

摘要

The purpose of the present invention is to provide a stator for a small high-power rotating electrical machine by suitably changing the coil shape of a distributed winding coil, thereby controlling the diameter-enlargement of the coil end due to interphase insulation while controlling the diameter-enlargement of the coil end due to lane changes. A stator winding is provided with 48 winding bodies (22) which are respectively produced by winding a continuous insulation-coated conductor wire having no connection sections, arrayed at a pitch of one slot in the circumferential direction by being attached to a first slot (131), a second slot (132), and a third slot (133) continuously provided in the circumferential direction at an interval of six slot angles. The winding bodies (22) are configured in a δ-shaped coil pattern formed by inserting a conductor wire (19) into the first slot (131), the second slot (132), the third slot (133), and the second slot (132) in that order, while alternately changing the insertion direction into the first slot (131), the second slot (132), and the third slot (133) from the axial direction.
