Abstract: An electric motor having a cage pivotally mounted at one end to a post interior a housing by a first bearing and at its other end by a second bearing between the exterior of the cage and the interior of the housing. A first stator is mounted to the interior of the cage and has an output shaft and first rotor interior thereto. A second rotor is mounted to the exterior of the cage and interior a second stator which is mounted interior the housing. The second stator is driven with a control signal which is a function of the measure reaction torque experienced by the first stator to produce a counter torque to balance the reaction torque. A consistency transmitter mounted on the output shaft produces torque on the first stator as a function of the consistency of the material in which it is rotated.
