Abstract
In a slotless permanent magnet rotary electric machinery, comprising a substantially cylindrical rotor () incorporated with a permanent magnet (), a stator iron core () surrounding the rotor; and a coil () provided between the rotor () and stator core () in a spaced relationship with respect to the rotor (), the coil () comprises a plurality of turns which are shifted from one turn to another along the circumferential direction in a mutually overlapping manner; and the coil turns are formed by a conductor () having an elongated cross section, a long axis of the cross section extending in a radial direction. This provides rotary electric machinery which can significantly reduce loss in a high speed range without substantially increasing copper loss.
