Abstract

PURPOSE:To facilitate an easy incorporation of a stator of a motor for electric film winding camera into a spool, by forming the stator with the end part of axial direction plus the thin extended part of a permanent magnet. CONSTITUTION:A permanent magnet 12 is installed inside the inner barrel 2 formed with a magnetic shielding plate. At the same time, the lower parts of the yokes 10 and 11 are attached close to the magnet 12 for magnetization. Then the yokes 10 and 11 inside the stator, and at the same time a brush 14 and commutator 16 are provided to form a DC motor. In such constitution, a camera motor having a small size in the radius direction can be obtained to be suitably incorporated into a spool.
