Linear electric motor
(stepper) BALDOR Dodge Reliance

Baldor provides industry with the widest range of linear motors, linear stages and controls. Being a leader in linear motor design and manufacturing, Baldor continually develops advanced products and innovations to meet a variety of linear motion applications.

Linear motors provide unique speed and positioning performance advantages. Linear motors provide direct-coupled motion and eliminate mechanical transmission devices. They offer substantial improvements over applications using ball screws, timing belts, etc. The rugged mechanical design provides accurate motion and precision positioning for hundreds of millions of cycles. Baldor linear motors and stages are used in thousands of successful applications worldwide.

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; speeds to 1.5 – 2 m/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 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.
