ABSTRACT:
The present invention is an air gap winding rotating electric machine in which the stator coils are disposed between the stator side magnetic shield and a thin-walled electrically insulating cylinder which surrounds the rotor. The stator coils are prevented from lateral movement by electrically insulating members inserted between adjacent sets of stator coils. In presently existing air gap winding rotating electric machines, these insulating members fit into slots in the magnetic shield; they are difficult to install and frequently become loose, resulting in the loosening of and possibly damage to the stator coils. In the present invention, the magnetic shield has inward projections instead of slots, and insulating members are secured by the use of taper keys, with the result that installation of the insulating members is easy and there is less chance of their coming loose than in presently existing machines, resulting in a more reliable installation of the stator coils.
