Abstract
The invention relates to a torque sensor assembly with an upper rotor mounted on an upper shaft axially disposed about a rotational axis, an outer lower rotor axially disposed about the rotational axis, an inner lower rotor axially disposed about the rotational axis between the upper rotor and the outer lower rotor, and at least one probe positioned between the outer lower rotor and the inner lower rotor, the at least one probe measures flux generated by the upper rotor and directed by the outer lower rotor and the inner lower rotor.
