Abstract
The magnetic field of a magnetoelectric valve motor with a misaligned rotor is calculated on the basis of conformal mapping. For the case of rotation of the eccentricity, expressions for the electromotive force (EMF) of the stator-winding idling and the electromagnetic moment are obtained. It is shown that this type of misalignment of the rotor causes a nonsinusoidal EMF and pulsation of the electromagnetic moment with a frequency three times higher than the mechanical speed of the rotor. At a fixed eccentricity, a variable EMF is induced along the rotor shaft causing an alternating current in the circuit: shaft–bearings–bearing-shields–stator-housing circuit.
