Title:
ROTARY ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2017/187860
Kind Code:
A1
Abstract:
With respect to a permanent magnet-type concentrated winding brushless motor, the present invention addresses the problem of disposing lead wires and cross-over wires, which cross over to teeth farther than adjacent teeth, on a wiring end part on an axial direction opposite side, in order to make the production work related to winding more efficient. The foregoing problem is solved by a brushless motor comprising a concentrated winding stator and a permanent magnet-type rotor, wherein a stator winding is wound so that: the number of windings of winding wires for teeth connected to lead wires is made a half integer, or in a case where there are winding wires adjacent to the winding wires of the teeth connected to lead wires and connected thereto the total number of windings of such winding wires is made a half integer; and the number of windings of winding wires of teeth which are connected, using cross-over wires, farther than being adjacent to the winding wires of the teeth connected to the lead wires or the winding wires of teeth adjacent to such winding wires and connected thereto is made an integer, or the total number of windings of winding wires of teeth adjacent to the winding wires of the teeth which are connected, using cross-over wires, farther than being adjacent, and connected thereto is made an integer.
