Term Explanation
VC linear actuator /
VC linear drive
VC = Voice Coil
The feed is generated by the Lorentz force on an energized
coil (PIMag® principle) that couples to a runner. The V-273
thus combines a relatively long travel range with a high
velocity and a high resolution.
Max. push/pull
force
Maximum force in the direction of motion.
Position or velocity control:
When a counterforce is exerted on the linear actuator, the
linear actuator counteracts it with maximum force to
maintain the target position or target velocity. When the
counterforce exceeds the specified value of the push/pull
force (p. 37), displacements or changes in velocity can occur.
