PURPOSE:To provide a DC motor unit which can be started through a power supply having low current capacity, with high driving force. CONSTITUTION:In a DC motor unit comprising a movable section permanent magnet 1, a plurality of coils 2-5, a distributor 8 for switching the current paths to the coils 2-5, and a position detector 7 for detecting the rotary position of motor movable section and delivering a switching signal to the distributor, a (pulsating means) 10 for pulsating the currents flowing through the coils 2-5 is provided in order to pulsate the currents, to be fed from the distributor 8 to the coils 2-5, at the time of starting a motor. |
