Abstract

PURPOSE: To manufacture a straightly-moving electric machine which has a high efficiency of operation and is easy to wind a wire and whose cogging force is little, by providing a fixedly magnetized field section and a rod-like armature core which has winding recesses and prescribed auxiliary recesses.
CONSTITUTION: A field section 2 made of a flat permanent magnet having magnetic poles on the surface is mounted on a moving body 1 so that the field section can be moved. A rod-like armature core 3 provided with winding recesses a∼f, whose number is six, for example, is fixed. Prescribed windings are provided in the winding recesses a∼f. Auxiliary recesses a'∼l' of smaller depth than the winding recesses a∼f are provided on projecting members 5a∼5g located between the winding recesses or at both the ends thereof so that the auxiliary recesses face the field section 2. The winding recesses a∼f and the auxiliary recesses a'∼l' are located at an almost equal spacing as a whole. As a result, the period of magnetic fluctuation of the armature core 3 is shortened to reduce the cogging force.
