Claim 0:
1. A motor, comprising:
a rotor assembly, comprising:
a first shaft and a second shaft, each shaft of the first and second shafts being rotatable about a horizontal axis and wherein the first and second shafts are parallel relative to one another;
a first rotor mounted on the first shaft and a second rotor mounted on the second shaft, the second rotor being positioned adjacent to the first rotor to form a rotor pair, each respective first or 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; wherein the first rotor and the second rotor collectively define:
a first pair of approaching permanent magnets of the plurality of permanent magnets, each respectively having outer faces that define a second magnetic polarity; and
a second pair of approaching permanent magnets of the plurality of 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; and

an electromagnet assembly having a distal portion positioned proximal to the rotor assembly, the electromagnet assembly including one or more outer coils wrapped around one or more ferromagnetic cores;
wherein application of electrical current in a first direction to the one or more outer coils energizes the distal portion of the electromagnet assembly with a first magnetic polarity that attracts the first pair of approaching permanent magnets towards the distal portion of the electromagnet assembly; and
wherein subsequent reversal of the direction of the electrical current upon rotation of the first pair of approaching permanent magnets past the distal portion of the electromagnetic assembly energizes the distal portion of the electromagnet assembly with 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 the second pair of approaching permanent magnets towards the distal portion of the electromagnet assembly.
