  • Publication number: 20220037974
    Abstract: A DC motor is configured so that, while either one of a pair of power feeding brushes makes contact with two commutator segments, the other makes contact with only one of two commutator segments. The DC motor is further provided with: a plurality of coils; a filter unit; and a calculation unit. The number of turns of a predetermined coil among the plurality of coils is different from the numbers of turns of the other coils. The filter unit allows the passing of the waveform of current generated on the basis of the fact that the numbers of turns are different from each other, and interrupts the waveform of current generated at the switching of the states of the contacts of the power feeding brushes to the commutator segments. The calculation unit calculates a rotational speed from the waveform passed through the filter unit.
