Zusammenfassung:ARMATURE STRUCTURE FOR PERMANENT MAGNET D-C MOTOR A permanent magnet d-c motor is described in which the weight and cost of the armature is substantially reduced by removing some of the steel laminations. To maintain performance, the remaining laminations are spaced apart so that the axial length of the armature remains unchanged and the width of the armature winding slots is kept to a minimum to prevent magnetic saturation within the armature teeth. Two means for spacing the laminations are described.
