|
In 2007 Exlar introduced the GSM Series Actuators as the successor to the SR Series. The differences between the GSM and the SR Series of actuators is shown below. For the details associated with these differences see the links at the bottom of this page or go to GSM overview.

Excellent Ball Screw Replacement
The SR Series of linear actuators from Exlar povides a cost effective solution, perfect for replacing ball screw actuators. This compact design incorporates Exlar's patented roller screw technology with an integral brushless servo motor for medium to high performance motion control applications. The SR Series offers a completely integrated actuator, competitively priced with low performance, short-lived ball screw actuators. The SR design provides a smaller package with higherspeed and load capacity than ball screws and other traditional rotary to linear conversions. SR Series also offers 5 times the travel life of similarly sized ball screw actuators. Selection of the proper feedback configuration allows SR Series actuators to be powered by nearly every brand of brushless motor amplifier on the market. This flexibility allows SR Series actuators to be incorporated into the highest performance single and multi-axis motion control systems in use today. In applications varying from food and beverage packaging, to multi-axis turning centers to air-craft assembly, the SR Series of actuators show incredible performance and durability.
New T-LAM Segmented Lamination Technology
Exlar's new T-LAMTM technology incorporated into the motor design provides a solution with 35% more motor torque. These efficiencies are a result of the limited heat generation qualities inherent in the segmented stator design.The elimination of end turns in the stator, and the use of thermally
|
| conductive potting removes the parts most suspectible to failure in a traditional motor.
Other benefits of the new T-LAM technolgoy include:
- Neodymium iron boron magnets provide high flux density and maximum motor torque.
- Thermally conductive potting of the entire stator provides increased heat dissipation and provides protection from contamination in oil-cooled units.
|
 |
- Each stator segment contains individual phase wiring. External winding of individual segments provides maximum slot fill for maximum motor performance.
- Motors with T-LAM technology have Class H insulation systems compliant with UL requirements.
