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.

The 3 phase brushless (or AC servo) linear motor is ideal for high force, long stroke, closed loop servo, and linear motion applications. They can be used at speeds up to 240 in / sec [6 m / sec]. They are capable of very precise position, velocity and acceleration control when coupled with a linear encoder.
The 3-phase coil assembly can be commutated trapezoidally using optional Hall Effects or sinusoidally using software commutation in conjunction with the appropriate motion controller and sinusoidal amplifier.
The short laminated moving coil assembly moves over the top of a magnet assembly. A customer supplied bearing system is required to guide the moving coil assembly and to maintain a .030" [0.75 mm] clearance between the coil and the magnet assembly.
There is a large magnetic attractive force between the coil and magnet assembly. The bearing system must be able to withstand this force in addition to whatever payload is being carried.
The power to the motor (from a customer supplied PWM 3 phase brushless servo amplifier) is supplied to the moving coil via a power cable.
The motors are available in 6 different widths and 4 different coil assembly lengths.
Advantages:
* Very low cogging
* High speed and accelerations of heavy payloads
* Capable of high forces
* Uses standard 3 phase brushless amplifier

A Linear Induction Motor (LIM) is a non-contacting, high speed, linear motor that operates on the same principal as a rotary, squirrel cage, induction motor. They are capable of speeds up to 1800 in/sec [45 m/s] and are typically used in applications where accurate positioning is not required. LIM’s can also be operated at stall to produce static thrust
The 3-phase coil assembly can be directly connected to the AC line for single speed applications or to an adjustable frequency drive for precise variable control of the speed of the motor. The motors are reversible and can also be dynamically braked.
The laminated coil assembly (shown above) is used in conjunction with a customer supplied aluminum and steel reaction plate to produce a force. A customer supplied bearing system is required to maintain the .040” - .060” [1 – 1.5 mm] air gap between the coil assembly and the reaction plate. The length of the reaction plate is equal to the coil length plus the stroke.
The amount of thrust produced by the LIM is proportional to the active surface area of the motor.
There is an attractive force between the coil assembly and the steel in the reaction plate only when power is applied to the coil assembly.
Multiple coil assemblies can used together to produce larger forces.
If the reaction plate is a disc, then rotary motion can be produced.
Either the LIM or the reaction plate can move while the other is fixed.
In hostile environments a non-magnetic stainless steel barrier can be used between coil assembly and the reaction plate to provide a seal.
Advantages:
* Only 2 parts
* Wide speed range
* No Maintenance
* Non-contact
* Ease of Control and Installation

Baumüller linear motors have been designed for use as direct drives with synchronous motors. Customized motor concepts can be created using a modular system, meaning that Baumüller linear motors can achieve maximum thrust forces of up to 14,750 N.
Baumüller linear motors are synchronous motors. They consist of a primary with a wound lamination stack and a secondary with permanent magnets (magnetic strip). The primary is laminated with carbon fiber. This allows Baumüller linear motors to achieve consistently high stiffness and maximum continuous force, thanks to their improved capacity for heat dissipation.
LSA - The plug & play solution
LSE 10 - The customized solution
LSC - The ironless solution
LSE 50-90 - The solution for logistics applications
The scope of products and services provided is not merely limited to linear motor components. On the contrary, Baumüller offers the user a plug & play solution with clearly defined interfaces that can be immediately connected to his machine, in the form of a very compact and flexibly designed complete linear axis, LSA, which is essentially comprised of linear components, a guidance system, a mechanical structure, and a length measuring system.

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

A DDL motor is basically a rotary motor that is laid out flat and directly coupled to the driven load. With this configuration, all mechanical transmissions, such as ball/lead screws, rack and pinions, belts/pulleys, and gearboxes are eliminated. This in turn eliminates backlash and other problems associated with these mechanical transmissions. DDL designs deliver exceptional high performance, extremely high stiffness, very high dynamic speeds and accelerations, high positional accuracy, higher throughput, compact mechanical assembly, smooth, error-free motion, zero maintenance, and quiet operation.
