Vertical applications

Linear motors in vertical applications often require a counterbalance mechanism to prevent dropping the load in

the event of power interuption. The counterbalance neutralizes the gravitational force, making an additional

continous force of the linear motor superfluous. The inertia of the motorsystem though could increase. For

counterbalance mechanisms can be thought of springs, pneumatic cylinders or counterweights.

When the moving mass is small, especially when the gravitational force is significantly smaller then the continu-

ous attraction force, the application could do without a counterbalance mechanism.
