Claim 5:
6. A method, comprising:
providing a rotor assembly in association with an electromagnet assembly, the electromagnet assembly having a distal portion, comprising:
a first rotor mounted on a first shaft and a second rotor mounted on a second shaft, each first and second rotor including a plurality of permanent magnets arranged annularly about the associated first or second shaft that each define an outer face having alternating first or second magnetic polarities;
applying an electrical current in a first direction to one or more outer coils of the electromagnet assembly that energizes the distal portion of the electromagnet assembly with a first magnetic polarity that attracts a first pair of approaching permanent magnets of the plurality of permanent magnets of the first and second rotors towards the distal portion of the electromagnet assembly, the first pair of approaching permanent magnets each respectively having outer faces that define a second magnetic polarity; and
reversing, upon rotation of the first pair of approaching permanent magnets past the distal portion of the electromagnet assembly, the direction of the electrical current applied to the one or more outer coils of the electromagnet assembly to energizes the distal portion of the electromagnet assembly with an-a second magnetic polarity that repels the first pair of approaching permanent magnets away from the distal portion of the electromagnet assembly to an advanced radial position and simultaneously attracts a second pair of approaching permanent magnets of the first rotor and the second rotor towards the distal portion of the electromagnet assembly, the second pair of approaching permanent magnets each respectively having outer faces that define a first magnetic polarity and being positioned adjacent to the first pair of approaching permanent magnets.
