摘要： An electric machine is provided to reduce noise by generating the same circuit break currents at two partial coils of symmetric windings to compensate radial forces of each partial coil. An electric machine includes first and second hammer brushes, a spring lever, an amateur, two magnetic poles, and a commutator(10). The commutator includes 11 commutator bars(11). The amateur includes 12 cogs(23) and 12 amateur slots(24). The first and second hammer brushes are in contact with the commutator(10) by the spring lever. The winding of a first partial coil is set inside the 6th amateur slot(24) between the 6th and 7th cogs inside the first amateur slot(24) between the first and second cogs. The winding of a second partial coil is set inside the 7th amateur slot(24) between the 7th and 8th cogs inside the 12th amateur slot(24) between the 12th and first cogs. The terminals of the first and second partial coils are electrically connected to adjacent commutator bars. The first and 6th amateur slots(24) and the 7th and 12th amateur slot(24) are placed to face each other to place two partial coils symmetrically to the rotating axis of the amateur.
