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.

A torque compensated electric motor comprising: a housing; a cage; a post mounted to and extending interior said housing; a first bearing interconnecting a first end of said cage and said post so that said cage rotates about said post; a second bearing interconnecting the exterior of the second end

A torque compensated electric motor comprising: a housing; a cage; a post mounted to and extending interior said housing; a first bearing interconnecting a first end of said cage and said post so that said cage rotates about said post; a second bearing interconnecting the exterior of the second end of said cage and the interior of said housing; a first stator mounted to the interior of said cage; an output shaft extending from said housing and said second end of said cage and rotatably mounted to the interior of said cage; a first rotor mounted to said output shaft interior and axially aligned with said first stator; a second rotor mounted to the exterior of said cage; a second stator mounted to the interior of said housing concentric to said second rotor; means for measuring the reaction torque experienced by said first stator; and control means for providing a control signal to said second stator as a function of said measured torque to produce a counter-torque in said second rotor to balance the reaction torque experienced by said first stator.
