Abstract
A rotary motor shaft extends through a rheological brake unit through which variable braking resistance to rotation of the motor shaft is applied while it undergoes rotation in response to torque mechanically applied thereto in sequence through a peripheral gear by a selected pair of diagonally aligned electro-magnetically energized push-rod actuators adjustably positioned axially along a varying diameter section of the gear under electrical control for stroke change to yield a variable output torque.
