Gravity Compensator

Magnetic Innovations developed a patented Magnetic Gravity Compensator series (MGC) which has proven itself in various high-end industrial equipment. 

Our MGC avoids direct cross talk of parasitic forces from the environment disturbing the accurate controlled moving part. This is needed for high -end 6-DOF controlled mechatronic applications in which it is sometimes beneficial to obtain a low stiffness between the static and moving part. 

Usually, the gravity compensator technology used in the area of MGC is based on reluctance forces and yields a high passive or active stiffness, however. This is why our MGC can be applied where high speed, high force density and a high reliability & lifetime are required both in normal industrial and in vacuum environments.

Key features

    • Magnetic bias force compensates gravity and eliminates static dissipation of coils
    • High reliability and lifetime due to the absence of moving wires
    • Low (contactless) stiffness between static and moving magnet parts
    • No heat load on the moving part, single phase actuator, water cooling possible
    • Suitable for vacuum environments
    • Radial clearance for 6-DOF control
    • High peak and continuous force possible
    • A=including Z-actuator, P=only Bias force
