Abstract
A motor for rotating a magnetic disk comprises an armature concentrically secured to a center shaft affixed to a mounting frame. A rotor frame having a cylindrical side wall of uniform outside diameter is rotatably supported in a cantilever fashion on a free end of the center shaft by a pair of bearings encircling the outer peripheral surface of the armature and a magnetic disk support that projects from the side wall. A permanent magnet secured inside the side wall is disposed to interact with magnetic fields produced by the armature. The cantilever support makes it easier to bring armature leads through a hole in the mounting frame as a part of the manufacturing process.
