Abstract
A light deflecting electric motor includes a stator assembly including a base, a fixed shaft fixed to the base and a stator mounted on the base, a rotor assembly including a rotating member rotatably mounted on a plurality of bearings further mounted on the fixed shaft, a polygon mirror mounted on the rotating member and a rotor mounted on the rotating member, the rotor assembly having a center of gravity located between the bearings, and a balancing plane provided in the vicinity of a plane which is generally perpendicular to a center of rotation of the rotor assembly and passes the center of gravity of the rotor assembly.

A light deflecting electric motor comprising:
- a stator assembly including a base, a fixed shaft fixed to the base and a stator mounted on the base;
- a rotor assembly including a rotating member rotatably mounted on a plurality of bearings further mounted on the fixed shaft, a polygon mirror mounted on the rotating member and having an outer circumferential surface and a rotor mounted on the rotating member, the rotor assembly having a center of gravity located between the bearings, the rotor assembly being disposed so that a plane which is generally perpendicular to a center of rotation of the rotor assembly and passes the center of gravity of the rotor assembly passes an inside of the polygon mirror;
- and
- a balancing plane provided in the vicinity of said plane.
