摘要： A method of making a machine system includes assembling sensing elements with a sensor frame, and contacting ferrite cores of the sensing elements with a locating tool to conform an arrangement of the sensing elements to a cylindrical shape of a surface of the locating tool. The sensing elements are secured to the sensor frame in the determined arrangement, and coupled with a housing of a machine system to monitor position of a rotatable component therein. The ferrite cores may be E-type cores, with bridge connections used to sensitize the sensing mechanism to displacement of a rotatable component in X, Y, and Z directions.

摘要： Axial magnetic bearings that include a primary winding(s) and one or more compensation windings that provide compensation such that operation of the first and/or second primary windings and the compensation windings results in a net magneto-motive force of around zero ampere turns. Current can selectively flow through one or both of the primary windings of an opposing pair of axial magnetic bearings, while current flows through the compensation windings in manner that compensates for the magneto-motive force generated by the primary winding(s). In at least situations in which the number of turns for at least one pair of compensation windings is generally equal to the number of turns of each primary winding, the net magneto-motive force generated by current flowing through a primary winding of one axial magnetic bearing and through the compensation windings of both axial magnetic bearings can generally be zero.
