A tandem Coil armature in which a pair of spaced-apart field coils [91,92] are wound on bobbins [12,14] mounted within a set of magnetic core pieces [16,18,20,22]. Two L-shaped conductors [27,28] pass through passageways through the core pieces and connect the windings to slip-rings [72,74]. Insulated conductor carriers [31,32,37,38] sized to mate with passageways and recesses in the core pieces support the L-shaped conductors and electrically insulate them from the magnetic core piece material. The core pieces are mounted for rotation with the rotor shaft [10] and include interleaved claws at their periphery which form the rotors magnetic poles.
