Abstract
An electric submersible well pump assembly includes a rotary pump and an electrical motor. The motor has a motor housing filled with a dielectric lubricant. A stator formed of a stack of stator disks with a stator bore is stationarily mounted within the motor housing. A motor shaft extends through the bore. A rotor is mounted to the shaft for rotating the shaft and has a stack of rotor disks. Axially spaced-apart radial stabilizing portions along the rotor have outer peripheries that are greater in outer diameter than remaining portions of the rotor. The outer peripheries of the stabilizing portions rotate with the rotor and are closely spaced to the inner diameter of the stator to radially stabilize the shaft.
