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

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 motors provide the following advantages:
High repeatability - resolution to 0.1 microns - this makes sure all parts produced are accurate and identical
Highly accurate - to 2.5 micron/300 mm - provides precise machine operation for precision parts
No backlash - direct drive has no backlash such as with lead screws, gears, etc. this improves the accuracy of the part or operation
Faster acceleration - from 1 to over 10 G's - this leads to shortened cycle times and improved productivity.
Higher velocities - speeds to over 8 meters/sec - to position the payload faster
Long term reliability - only two parts with only one moving part - this leads to simplicity and improves the applications reliability
No wear or maintenance - no contacting parts, thus reducing component friction and wear
Ease of installation - linear motors are designed to allow for alignment tolerances. Misalignment produces no degradation of performance

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

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.

QUICKSHAFT® Linear DC-Servomotor series LM 1247
NEW TECHNOLOGY
Up to 9,4 N impact
Boasting a slimline design of 12.5 x 47 mm and a weight of only 56 grams, at full power this drive provides an impact force of 9.4 N. For the standard product the travel is 20 mm; optionally travel up to 80 mm is also available. The Linear DC-Servomotor comprises an electromechanical part, a metal housing made from a non-magnetic alloy, a coil and an analogue Hall sensor. A precision sliding metal rod equipped with a permanent magnet completes the linear motor, and together they make a dynamic, high-performance drive in a modern design.
The activation of these new QUICKSHAFT Linear motors is provided via the optimally matched motion controllers of the MCLM 3003/06 series, which are also available with a CAN interface. The free FAULHABER version 3 "Motion Manager" software provides rapid and easy control of the linear motor. In numerous applications this newly developed drive has proved itself to be the best-in-class solution for highly demanding linear movement and positioning tasks.

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.
