PURPOSE:To provide a rotating electric machine without an auxiliary pole, where output is great and starting property is excellent, by providing, in the same condition, auxiliary grooves for generating magnetic nonconformity with the center of each projection as the boundary, for each of the faces opposed to the magnetic part in each projection of an armature iron core. CONSTITUTION:When current are let flow to windings 4a, 4b, 4c, and 4d, rotating torque is generated by the electromagnetic interaction between the magnetic flux of a field part 1 and the current, and it rotates to the armature iron core 2. Since the widths of main projections 2a, 2b, 2c, and 2d can be taken by the amounts that the auxiliary poles are removed, the output becomes large. When the magnetic field 1 and the center of each projection accord with each other, as for magnetic attraction, difference occurs between right and left by the auxiliary grooves 5a1, 5a2, 5b1, 5b2, 5c1, 5c2 5d1, and 5d2 provided in symmetry, and it produces clockwise torque. In the condition that the current is not let flow, the center of the magnetic field 1 stops at the position slipped a little by the above torque, and the center never accords at start up, so the start-up becomes possible. |
