Linear Stepper Motor, Single Axis - LMSS series
Baldor's open loop linear stepper motor provides the most economical linear motor positioning package. The "forcer" consists of a 2 or 4 phase motor assembly encapsulated in an aluminum housing supported by bearings. The "platen" consists of photo-chemically etched teeth on a steel bar available in lengths cut per customer specification. The LMSS series provides forces to 220 N (50 lbs); speeds to 1.5 - 2 m/sec (890 in/sec); acceleration to 1 G.
Linear Stepper Motor, Dual Axis - LMDS series
Baldor's dual axis stepper package provides open loop positioning along two axis of travel. An integrated air bearing system floats the "forcer" less than 25 micrometers (0.001 inch) above the photo-chemically etched steel plate. Preload for the bearing system is provide by the magnetic attractive force between the forcer and the platen. The LMDS may be mounted face up or inverted. A position verification system is available to close the loop.
