How fast can the Linear Shaft Motor go?
While the Linear Shaft Motor itself does not have inherent speed limitations. There are several factors that can limit the maximum speed of a Linear Shaft Motor system. The control must provide sufficient bus voltage to support the speed requirements. The encoder itself must be able to respond to that speed and its output frequency must be within the controllers capability: for example, with a 0.5 micron encoder and a speed of 5 m/s, the controller must handle 10MHz. Finally the speed rating of the stage’s bearing system must not be exceeded: for example, in a recalculating ball bearing, the balls start to skid (rather than roll) at about 5 m/s. Under the right conditions the Linear Shaft Motor can reach speeds exceeding 10 m/s.
