ABSTRACT:
A rotor for an electrical machine comprises a bobbin, a winding, and two pole pieces. The winding comprises a wire wound around the outer surface of the bobbin. At least one flat on the outer surface of the bobbin is imparted on the winding, mechanically locking the winding to the bobbin. The bobbin is concentrically disposed over hubs on the two pole pieces, the bobbin and the hubs having complementary flats which only allow assembly of the bobbin and the hubs when the flats are aligned. A method for producing a rotor comprises providing a bobbin with at least one flat on its outer surface and at least one flat on its inner surface; winding wire around the outer surface of the bobbin to create a winding with at least one flat in it; providing two pole pieces with hubs with complementary flats to the at least one flat on the inner surface of the bobbin; aligning the flats on the hubs and on the inner surface of the bobbin; and inserting the hubs into the bobbin.
