The use of magnetic bearings in angular momentum exchange effectors has the primary advantage that physical contact between the rotor and stator is eliminated. This leads to greatly extended life, increased reliability, and reduced vibrations. Several effectors operating on magnetic bearings have been demonstrated in previous research efforts. These were sized for use in small satellites. For conventional magnetic bearings, which employ magnetic cores, high torsional loading may require that the magnetic structure be excessively massive. This paper discusses an alternative magnetic bearing design which employs a superconducting coil and eliminates all conventional magnetic structures. The baseline approach is to replace the magnetic structure of a conventional magnetic bearing with a superconducting coil. In the superconducting magnetic bearing, a single coil replaces two PM structures in order to produce an energy-efficient, light-weight design.
