Abstract
It is well known that the rotational power loss differs if the flux vector is rotated in either a clockwise or an anticlockwise rotation direction. An analysis is presented that shows that averaging the clockwise and anticlockwise values introduces an additive error that is dependent on the angular misalignment between the measuring sensors. Equations to minimise this error are presented and validated by application to experiments on electrical sheet steel.
