Abstract
An axial flux electrical machine including a housing, a stator located within the housing, a rotatable shaft carried by the housing by means of at least a main bearing, and a rotor fixed to the shaft within the housing. Magnetic attractive forces between the rotor and the stator produce an axial thrust on the main bearing and a biasing means (preferably in the form of a spring) is arranged to urge the shaft in a direction opposite to the axial thrust so as to reduce the net load on the main bearing. This reduction in net load on the main bearing increases bearing life and improves motor efficiency.
