And where are they typically used?
Our voice coil motors are, for example, suitable for scanning applications with travel ranges up to a few tens of millimeters. Even solutions with hollow shafts can be realized, for example, for use in medical endoscopes. Our linear motors can be used for significantly larger travel ranges. Iron-core linear motors are suitable for applications requiring high forces and accelerations with limited installation space whereas ironless linear motors are suitable for positioning tasks with very high demands on precision in the smallest installation spaces.
Our torque motors can, for example, be built particularly flat or somewhat deeper if higher torque densities are required. In addition, hollow shafts of different sizes can be realized, for example, to feed through cables, optical beams, or similar things. They are mainly used in rotation stages and are often also stacked onto PI hexapods or XY(Z) setups.
