Abstract: An axial flux machine comprising a rotor mounted about an axis of rotation and having two axial faces. A first stator ring is positioned on the rotor adjacent to a first axial face, to define an air gap, between the first stator ring and first axial face. The first stator ring is formed by stator ring segments, each having a radially inner and outer edge. A second stator ring is positioned on another side of the rotor, adjacent to the second axial face, to define an air gap between the second stator ring and second axial face. The second stator ring is, also, formed by stator ring segments, each having a radially inner and outer edge and corresponding to a first stator ring segment. The stator ring segments are deflectable in unison in response to axial deflection of the rotor, to maintain the air gaps, due to link elements.

Abstract: The present invention provides a method of controlling the height of a looper in an inter-stand section of a hot strip mill that overcomes the problem of looper instability due to looper inertia without the need for the controller of upstream rollers to have a reduced gain. The inter-stand section of the hot strip mill comprises a pair of upstream rollers driven by a main motor and a looper driven by a looper motor. The method comprises the steps of: calculating a desired speed trim to be applied by the main motor; estimating the inertia of the looper; calculating a torque necessary to overcome the inertia of the looper from the speed trim, the estimated inertia of the looper and a sensitivity calculated from the geometry of the looper; and controlling the main motor to apply the speed trim to the upstream rollers and controlling the looper motor to apply the calculated torque to the looper.
