ABSTRACT:
A driving assembly of camera shutter and diaphragm comprises a first stator, a second stator, a coil set and a rotor. The coil set is installed between the first stator and second stator. A first wing is axially extended from a round periphery of the first stator and a second wing is axially extended from a round periphery of the second stator. Each of the first stator and second wing is a round cambered sheet. In assembly the first stator and second wing are formed as a space for receiving the rotor; thus the rotor is driven to rotate by the magnetic force of the first wing and second wing so as to drive the diaphragm and shutter. Each of the first wing and second wing has a plurality of parts which are formed around the respective stator and are spaced with an equal spaced.
