Dual Axis Linear Stepper Motors

Dual-axis planar linear stepper motors are ideal for open loop positioning applications with light payloads. They can be used at speeds up to 80 in /sec [2m/sec] and strokes up to 40” x 60” [1 m x 1.5 m]. Linear stepper motors are capable of very precise position, velocity and acceleration control when coupled with a microstamping drive and indexer.The moving assembly called the “forcer” is supported by magnetically preloaded air-bearings imbedded in the active surface of the forcer between the forcer and platen. The bearings are designed to support the customer’s payload and to maintain the required .001” [0.025 mm] gap between the platen and the forcer.The two axis step and direction signal from a microstepping drive, to the 2 or 4 phase forcer is supplied via a power cable. The motion achieved with a full step is .010” [250 microns] and with a microstep it’s .00004” [1 micron].
