"COMMUTATORLESS D.C. MOTOR WITH ELECTRONIC COMMUTATION" ABSTRACT OF THE DISCLOSURE This d.c. motor has a disc-shaped rotor carrying permanent magnets having their magnetic axes parallel to the motor shaft and on both sides of the rotor fixed arma- tures, each armature comprising a rosette-shaped, flat lap armature winding in which the coils partially overlap each other, a slotless iron ring having a flat face to which the coils are fixed, and a connection ring divided into insulat- ed segments receiving the ends of the coils adapted to be energized separately by means of an electronic commutation circuit controlled by a rotary coder, the groups of segments to which the ends of the coils to be energized in parallel are connected being interconnected by conducting wires extend- ing along the ring. All the component elements of the arma- ture are embedded in plastic material and constitute a compact assembly. If desired, the winding may be of the wave winding type. -1-
