l。With this configuration, when the rotor 10 is energized at this position and the coils l 6 a and l 6 b are energized, the rotor 10 starts rotating in the direction of the arrow, and as the rotor 10 rotates, the commutator 20 also rotates in the direction of the arrow. The rotor 1 rotates in the direction of
0 rotates 90 degrees, the slider 20 of the commutator 20
The power supply brush 32b1 that was suspected of sliding on b is the slider 20a.
The power supply brush 3 was in sliding contact with the slider 20a.
2b2 is in sliding contact with the slider 20b, and is a coil brush 32a.
