1. A magnetic bearing thrust stator, comprising: a plurality of stator sectors, each stator sector of said plurality of stator sectors configured to abut against another stator sector of said plurality of stator sectors during operation of the magnetic bearing thrust stator, and each stator sector comprising: a semi-circumferentially slotted stator portion comprising a plurality of semi-circumferential poles;a first coil portion shaped to fit substantially within said semi-circumferentially slotted stator portion, and said first coil portion defining a coil radial axis that is configured to extend within a plane oriented substantially perpendicularly to a longitudinal axis of a rotating shaft, said first coil portion comprising: a pair of semi-toroidal portions coupled by an opposing pair of U-shaped bends, each of said opposing pair of U-shaped bends extending axially from said pair of semi-toroidal portions and extending substantially perpendicularly to said plane; anda second coil portion shaped to fit substantially within said semi-circumferentially slotted stator portion and configured to be controlled independently from said first coil portion,wherein said first coil portion of each stator sector is configured to electrically couple to a corresponding first coil portion of an abutting stator sector during operation of the magnetic bearing thrust stator. 2. The magnetic bearing thrust stator of claim 1, wherein: said semi-circumferentially slotted stator portion comprises a plurality of substantially parallel curved slots. 3. The magnetic bearing thrust stator of claim 1, wherein: said first coil portion is configured to fit substantially within a pair of slots of said semi-circumferentially slotted stator portion. 4. The magnetic bearing thrust stator of claim 1, wherein: a first semi-circumferential pole from said plurality of semi-circumferential poles is opposite in polarity from each adjacent semi-circumferential pole of said plurality of semi-circumferential poles. 5. The magnetic bearing thrust stator of claim 1, wherein: said plurality of semi-circumferential poles comprises a first pole adjacent to a second pole,said first pole has a first magnetic polarity and said second pole has a second magnetic polarity, andsaid first magnetic polarity is opposite to said second magnetic polarity. 6. The magnetic bearing thrust stator of claim 1, wherein: said semi-circumferentially slotted stator portion comprises a semi-disc coupled to said plurality of semi-circumferential poles. 7. The magnetic bearing thrust stator of claim 1, wherein: said first coil portion defines a continuous closed loop. 8. The magnetic bearing thrust stator of claim 1, wherein: said magnetic bearing thrust stator is operatively configured to restrain movement of the rotating shaft along the longitudinal axis of the rotating shaft. 9. The magnetic bearing thrust stator of claim 1, wherein: said magnetic bearing thrust stator is configured to be operatively positioned adjacent to, but displaced from, a thrust rotor. 10. The magnetic bearing thrust stator of claim 1, wherein said first coil portion is configured to be electrically connected to a first amplifier and said second coil portion is adapted to be electrically connected to a second amplifier that is independent from said first amplifier.
