ABSTRACT:
A compact bearingless machine drive system includes: a first rotor segment; a first stator segment with the first stator segment including a drive winding and a first control winding; a second rotor segment; a second stator segment with the second stator segment including the drive winding and a second control winding; and a rotor shaft. The first and second rotor segments are attached to the rotor shaft. A common end ring is coupled between the first and second rotor segments. A drive inverter controls the drive winding to generate torque, and first and second control inverters control the first and second control windings to generate radial forces on the first and second rotor segments.
