PROBLEM TO BE SOLVED: To easily introduce inductance of a required size to suppress vibration and noise resulting from high-frequency components of an electric current which flows into a stator coil.SOLUTION: A rotary shutter device 1 (rotary plate driving device) comprises: a first motor 50A which rotates a first shutter plate 20; and a second motor 60A which rotates a second shutter plate 30. Stator coils 52, 62 of each motor are printed coils having a U-phase coil 7a, a V-phase coil 7b, and a W-phase coil 7c. An inductor 5 is inserted in electric connection routes 8a, 8b respectively which connect the U-phase coil 7a, the V-phase coil 7b of each motor and a drive control section 4 (first and second drive control sections 4a, 4b). The inductor 5 is mounted on a second substrate 3, and attached to the external section of first and second motor housings 11, 41. |
