Brushless dynamoelectric machines utilizing conventional DC armature construction. The winding of the armature is modified by providing a set of three leads to its coil ring circuit at points spaced angularly about 120 DEG . Electrical energy is carried in these leads instead of a commutator and brush set. In most versions of the machine, a shell rotates about the armature, while the armature is caused to remain stationary. The three lead lines are brought out parallel to the axis of rotation through a bearing supporting the shell. |
