Aerotech's "U-channel" brushless linear servomotors have proven ideal for robots, actuators, tables/stages, fiberoptics/photonics alignment and positioning, assembly, machine tools, semiconductor equipment, electronic manufacturing, vision systems, and in many other industrial automation applications. Aerotech linear motors are direct drive and consist of a noncontacting forcer coil and "U-channel" rare-earth magnet track. This design eliminates backlash, windup, wear, and maintenance issues associated with ball screw, belt, and rack and pinion based motion control and positioning systems. The noncontact design of the forcer and magnet track results in a maintenance-free system.

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

SL2 series
The SL2 synchronous linear motor with convection cooling is practically maintenance-free and offers maximum reliability and availability, high control quality, speed and accuracy.
SL2 synchronous linear motors are available in three models for speed classes 1, 3 and 6 m/s: SL2 Basic, SL2 Advance System and SL2 Power System. For longer travel distances, secondaries are available in different lengths and can be easily lined up with one another. The SL2 Advance System features a motor cooling unit, which provides even better cooling than SL2 Basic. A forced-air cooling fan gives the SL2 Power System a further power boost.
Your advantages
- SL2 motors save time during project planning
- Precise, reliable and safe at any speed
- Virtually maintenance-free

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.

Linear Brushless Motors Series DM
Key Features:
· Symmetric forcer
· Dual magnet track linear motor
· Steel core for high force density
· Lo-Cog for smooth motion
· Built-in thermal sensors
· Hall-effect sensors
· Water cooling option
· Modular magnet track for unlimited travel
· Magnets covered by stainless steel strip
Iron core linear motor DM Series is designed to provide the highest force density in the linear motor applications. Unlike conventional iron core motors, DM motors have dual magnet track to balance magnetic attraction forces and to remove any forcer magnetic preload from the bearings. This feature provides for quite operation with smaller linear bearings without concern for bearing life. Linear motor magnetic structure of the forcer also optimized to provide low cogging. Forcer have thermal sensors in a compact structure as well as Hall-effect sensors and can be provided with water cooling option. These motors are ideal in applications to move large payloads without effecting bearing life. Magnet tracks are stackable for any travel length.
