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.

H2W Technologies linear stepper motors are ideal for open loop positioning applications with light payloads. They can be used at speeds up to 80 in /sec [2 m/sec] and strokes up to 144” [3.6 m]. Linear stepper motors are capable of very precise position, velocity and acceleration control when coupled with a microstepping drive and indexer.
The short moving assembly called a “forcer” is guided by either roller or air-bearings along he precision ground track called a “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 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].
The linear stepper motor is a complete positioning stage with the motor, the bearings and the positioning system all built into one compact package.
Integrating a linear encoder with the stepper provides a closed loop system.
Advantages:
* Low profile and small cross section
* High Speed
* Low cost positioning stage solution
* No servo tuning required
* Multiple forcers on a single platen

Planar linear stepping motor consists of a forcer and stator . The stator is made as a flat plate that carries on its working surface a spaced toothed structure. The forcer contains two groups of orthogonal electromagnetic modules. The working surface of electromagnetic modules has a spaced toothed structure with a definite phase shift from pole to pole. To create an air cushion between one stator and the forcer the latter is provided with a built-in pneumatic system with jets.
We are produce two types of motors: planar motor without position feedback and planar servomotor with with Hall-sensors (HS) feedback
Possible fields of application.
Assembly operations in microelectronics and instrument engineering:
LSI and VLSI unwelding.
Probe monitoring.
Crystal fitting.
Surface mounting elements and units assembly.
Printed circuit board control.
Laser technological complexes.
Measuring machines.
