<P>PROBLEM TO BE SOLVED: To reduce electric power consumption during driving. <P>SOLUTION: A motor device includes: transmission parts hung on at least part of a rotor; driving parts having at least a plurality of capacitive driving elements and moving the transmission parts by the capacitive driving elements; a control part which makes the driving parts perform a driving operation for moving the transmission parts by generating a torque transmission state between the rotor and the transmission parts and a return operation for returning the transmission parts to a predetermined position by generating a torque non-transmission state between the rotor and the transmission parts; and a charge delivery part which supplies charges emitted by at least one of the plurality of capacitive driving elements to the capacitive driving elements. <P>COPYRIGHT: (C)2013,JPO&INPIT |
