Abstract
The invention pertains to equipment and methods in which the rotatable drive member of a variable speed motor, such as a switched reluctance motor, carries a rotatable pulp processing element (10). Magnetic bearings (22, 24) levitatingly support both the rotatable drive member (15) and associated rotatable pulp processing element (41) and control axial and radial positionning thereof relative to the axis of rotation of the drive member.
