An analysis of bearingless AC motors

IEEE Transactions on Energy Conversion, 1994
Several types of AC bearingless motors are proposed. These bearingless motors have conventional four-pole stator windings and additional two-pole windings, whose currents produce radial forces acting on the rotor. General expressions of the machine inductances and radial forces are derived for the cylindrical rotor and salient-pole motors.

AC induction motor specifications for larger AC motors

World Pumps, 2005
Increasing plant capacity can also increase headaches for the system specifier and motors present their own particular minefield. Robin C H Cowley of Baldor Motors promotes some thought into the specifying of larger AC motors. While the term larger is relative, here it covers some motors below 75 kw and certainly those above.
