 frame H'. These magnets or poles are wound with insulated coils, those diametrically [opposite] to each other being connected in pairs so as to produce opposite poles in each pair. This leaves six free ends which are connected to the terminals t.

The armature which is mounted to rotate between the poles is a cylinder or disk D of wrought iron, on the shaft a. Two segments of the disk are cut away as shown.

The generator for this motor has, in this instance, an armature A wound with three coils K K' K" at 60 degrees apart. The ends of these coils are connected respectively to insulated contact rings e e e' e' e" e". These rings are connected to those of the motor in proper order by means of collecting brushes and six wires forming the independent circuits. The variations in the strength and direction of the currents transmitted through these circults and traversing the coils of the motor produce a steadily progressive shifting of the resultant attractive force exerted by the poles G' upon the armature D and consequently keep the armature in rapid rotation. The special advantage of this disposition is in obtaining a more concentrated and powerful field. The application of this principle to systems involving multiple circuits generally will be understood from this apparatus.

Referring now to Figures 15 and 16: Figure 15 is a diagramatic representation of a modified disposition of the invention. Figure 16 is a horizontal cross section of the motor.
