Linear Motor Stages
Linear motor stages do not have ball screws and stepper motors to provide the stage
movement. Instead they use an induction motor that produces motion in a straight line.
Applying a current to the electromagnet produces a magnetic field which interacts with
the magnetic field of the permanent magnets and propels the stage along guided precision
rails.
Linear motor stages offer high levels of acceleration and velocity together with excellent
repeatability, accuracy and resolution.
