ABSTRACT:
An electrical coil assembly and method of manufacturing an electrical coil assembly having at least two interconnected electrical coils forming a coil pair with each coil formed with a multiple winding of wire. The electrical coil assembly preferably has at least one pair of electrical coils with a first coil, a second coil and a third coil aligned in tandem. The first coil is formed from a first wire having an inner end and an outer end with the first wire wound in a clockwise or counterclockwise direction from the inner end to the outer end to form multiple layers of the first wire aligned relative to one another in a single row. The second coil is located between the first coil and the third coil, and is formed from a second wire having an inner end and an outer end with the second wire wound in a direction opposite to the direction of the first wire to form multiple layers of the wire aligned relative to one another in a single row. The third coil is formed from a third wire having an inner end and an outer end with the third wire wound in the same direction of the first wire to form multiple layers of the wire aligned relative to one another in a single row. The inner end of the first coil is connected to the inner end of the second coil and the outer end of the second coil is connected to the outer end of the third coil.
