Abstract: The invention relates to a rotating electric machine, such as a dynamometer. The rotor of the machine comprises a circular row of resultant magnetic poles of which the polarity forms an alternation of opposed poles. The resultant poles each include a pair of permanent magnets in a “V”, each equipped with a north pole N, a south pole S, and opposed faces, where the magnet poles are located. In each resultant pole the magnets are disposed so as to have faces having identical polarities, which faces are oriented radially outwardly, facing towards one another, thus forming therebetween an angle β between 90° and 110°, which makes it possible to increase the efficiency. The invention also relates to a turbomachine test stand equipped with a dynamometer enabling a recovery of electrical energy. The invention also relates to a hybrid motor vehicle propelled by the rotating electric machine.

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.
