Inexpensive, with Linear Motor
PIMag® magnetic direct drive
3-phase magnetic direct drives do not use mechanical components in the drivetrain, they transmit the drive force to the
motion platform directly and without friction. The drives reach high velocities and accelerations. Iron core motors are used
when forces and accelerations need to be achieved in a limited installation space. The design with iron cores maximizes the
magnetic forces and ensures high thermal stability of the drive.
Crossed roller guide
With crossed roller guides, the point contact of the balls in ball guides is replaced by line contact of the hardened rollers.
Consequently, they are considerably stiffer and need less preload, which reduces friction and allows smoother running.
Crossed roller guides are also distinguished by high guiding accuracy and load capacity. Force-guided rolling element cages
prevent linear guide creeping.
Direct position measurement
Position measuring takes place directly at the motion platform with the highest accuracy so that nonlinearity, mechanical
play or elastic deformation have no influence on position measuring.
Application fields
Industry and research. Automation technology with high demands on dynamics and precision.
