Abstract

PURPOSE:To reduce an area projected to the outside of a printed wiring board by placing and providing semiconductor IC of a power control unit to a clearance obtained by changing arrangements of the stator windings placed and provided on the printed wiring board. CONSTITUTION:An open angle of a stator winding 2 with a flat shape is made to 36 deg., and when six windings are successively placed and provided so as to make 12 deg. of intervals between windings adjacent to each other on a printed wiring board, a clearance with an angle of about 72 deg. in which no winding is placed and provided can be made between the first winding 2-1 and the sixth winding 2-6. An area of the printed wiring board projected to the outside of the stator winding is reduced, a wiring pattern 1-1 connecting a power control unit to the windings is also shortened and the area of the printed wiring board can be reduced by placing and providing semiconductor IC 3-1 of the power control unit to the clearance of the printed wiring board.
