ABSTRACT:
The invention relates to an electric motor having armature means including a plurality of armature segments each rendered into a flat form and arranged in a same plane around a center rotation axis in a manner as to form a circular outline; magnet means including a plurality of permanent magnet segments arranged in a same plane opposite to the armature segments coaxially on one side thereof with an air gap being provided therebetween, each of the permanent magnet segments having end portions in the radial direction defined by a geometrical line dividing the permanent magnet segments one from another, the dividing line being designed to extend in avoidance to be in parallel with a normal extended from the center rotation axis of the armature segments, said dividing line of each permanent magnet segment extending in parallel with another dividing line of the adjacent magnet segment to provide therebetween a groove of a predetermined width.
