Direct Drive Type
The Direct Drive Type consists of a driven body and an EMI body. They are connected with the timing coupler. The formulation of timing coupler is as follows.
•Timing Coupler(Timing Coupler has only Torque value)
•Torque
* Timing Coupler includes only Torque

o The ground inertial reference frame is the frame A.
o The base marker (=reference marker) between an Eblock (base) and an EDT driven body (action) is the frame A.
o The action marker between an Eblock (base) and an EDT driven body (action) is the frame B.
o The base marker (= reference marker between the ground (base) and EDT EMI (action) is the frame A.
o The action marker between the ground (base) and an EDT EMI (action) is the frame C.
Gear Drive Type
The Gear Drive Type consists of a drive body (gear), driven body (gear) and an EMI body. A drive and a driven body are connected with a screw coupler. And the driven and EMI body are connected with the timing coupler. The formulation of screw coupler and timing coupler is as follows.
•Screw Coupler (A screw coupler has the torque and reaction force value.)
•Torque
•Reaction force (Fx, Fy)
* Fx & Fy are reaction force acting on the Drive / Driven body
