In a D.C., e.g. high current low voltage, dynamo-electric machine, e.g. motor or generator, comprising a stator having a permanent magnet field structure 6 presenting alternate polarity equispaced poles N, S, and a rotor 1 having in the planar air-gap machine shown a plurality of radial conductor blades 3 arranged in at least one layer and being bare on one of their faces near one end, such faces are contacted by at least one pair of brushes 7 situated immediately adjacent a pair of stator pole axes and electrically connected to a pair of terminals 8, and means 4 electrically interconnect the other ends of the blades to complete an electrical circuit between the terminals via only those blades directly contacted by the brushes. The means 4 shown is the integral outer peripheral ring of the printed circuit winding but in other embodiments it may be the inner peripheral ring or further brushes. The rotor is strengthened by bending over its periphery Fig. 2, not shown, or by a glued-on annulus. The structure 6 may be either a ferrite ring or separate magnets possibly with flux concentrating polepieces. The machine alternatively may be of the cylindrical air-gap type, the rotor being radially between a surrounding stator and an interior flux return member. |
