Torque compensated electrical motor

A rotary consistency transmitter 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;
• 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;
• and
• transmitter means mounted to the end of said output shaft exterior said housing for producing a torque on said first stator as a function of the consistency of material in which said transmitter means is rotated.
