Microprocessor Controlled Fluid Clutch

John A. Marshall, PHD University of Southern Maine

Key Words:

Hydraulics, mechanical power transmission, and rheology.

Perquisite Knowledge:

Elementary concepts of power transmission.


To observe the tunable characteristics of magneto-rheological fluids. To understand the potential power transmission advantages of these fluids.

Equipment and Supplies:

Magneto-rheological clutch assembly and power supply.


Magneto-rheological fluids change their flow characteristics when subjected to an electrical field. Response, which takes only milliseconds, is in the form of a progressive gelling that is proportional to field strength. With no field present, the fluid flows as freely as hydraulic oil (Korane, 1991).

Magneto-rheological fluids represent a technology that has the potential to widen the performance range of automated electromechanical and electrohydraulic equipment. Research and ongoing developments are refining this technology and experts predict an important future for these fluids.
