ABSTRACT:
The motor comprises a flexible circuit composed of a substrate disposed in an air gap between the stator and the rotor, bearing a coating of copper etched to produce the various circuit components. Conductive paths carry the current to brushes soldered on zones of the circuit. Another path leads to further zones constituting shorted turns interconnected by striated areas constituting resistor elements.
