GSX Series linear actuators combine the advantages of Exlar’s roller screw technology and T-LAM™ technology to create the next generation of linear actuators. Exlar uses a specially designed roller screw mechanism for converting electric motor power into linear motion within the actuator. Planetary rollers assembled around the actuator’s extending rod follow threads which are precisely machined on the inside surface of the actuator’s hollow armature. Linear motion is produced in precise synchronization with the armature rotation. Because this roller screw mechanism has an inherently larger cumulative contact surface, these actuators have a much longer working life, and can handle heavier loads at higher speeds than is possible from a similarly sized unit built around a ball screw system.
Exlar’s T-LAM segmented lamination stator technology delivers higher continuous motor torque than is available in traditionally wound motors. T-LAM technology consists of stator segments, each containing individual phase wiring for maximum motor performance. The improved efficiencies of the GSX Series are a result of the limited heat generation qualities inherent in the segmented stator design as seen above. The elimination of use of thermally conductive potting removes the parts most susceptible to failure in a traditional stator. Other design advantages include:
The GSM Series of linear actuators provides an excellent replacement for ball screw actuators. The GSM Series offers 5 times the travel life of similarly sized ball screw actuators in a more compact, cost competitiveackage. This design incorporates Exlar’s patented roller screw technology with an integral brushless servomotor for medium to high performance motion control applications. The GSM design provides a smaller package with higher speed and load capacity and longer life than ball screws and other traditional rotary to linear conversion mechanisms.
Selection of the proper feedback configuration allows GSM Series actuators to be powered by nearly every brand of brushless motor amplifier on the market. This flexibility allows GSM 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 aircraft assembly, the GSM Series of actuators show incredible performance and durability. Exlar’s T-LAM technology incorporated into the motor design provides a solution with 35% more torque in the same package size as traditional brushless motors. The efficiencies of the SR Series 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 susceptible to failure in a traditional stator. Other benefits include:
I Series actuators present a new range of alternatives for linear motion solutions. The I Series actuators offer all of the benefits of planetary roller screw technology, along with extreme flexibility in actuator mounting style, and the type of motor used to drive the actuator.
Roller screw technology has been the integral component in creating the most reliable, long lasting electromechanical actuators on the market. For the last 15 years, inverted roller screw actuators have provided a long-life, all-electric replacement for hydraulic cylinders in thousands of applications.
The EL Series has two types of linear actuators – EL30 and EL100.
EL30 actuators are rated for Class 1, Division 1, Groups B, C and D. The classification of „Class 1“ means that flammable gases or vapors may be present in the air in quantities sufficient to produce explosive or ignitable mixtures. „Division 1“ means that hazardous concentrations in the air may exist continuously, intermittently, or periodically under normal operating conditions. „Group B“ allows for atmospheres containing hydrogen, or gases (or vapors) of equivalent hazard, such as manufactured gas. „Group C“ allows for atmospheres containing etyhyl-ether vapors, ethylene or cyclo propane. „Group D“ allows for atmospheres containing gasoline, hexane, naptha, benzene, butane, alcohol, acetone, benzol, lacquer solvent vapors, or natural gas. EL Series actuators are not rated for operation in atmospheres containing acetylene.
EL100 linear actuators offer all the advantages of Exlar's patented inverted roller screw actuator designs in a Class 1, Division 1, Groups B, C, D and T3 explosion-proof package. The EL100 linear actuators also meet ATEX essential requirements and are in conformity with the EU ATEX Directive 94/9/EC.
For operation in a process control system, the Exlar electric actuator solution provides many benefits:
The FT Series of linear actuators force tubes use a roller screw mounted inside a telescoping tube mechanism. The follower is attached to the moveable force tube, which then extends and retracts as the screw rotates. The FT Series is designed to be compatible with a wide variety of standard motors. Motor mounting and gearing configurations are available to meet nearly any application's requirements. The standard product offering includes three frame sizes with strokes from 12 to 96 inches and a load rating up to 40,000 lbf.
The K Series actuators from Exlar provide a truly universal solution for rod style actuator applications. The series is available with the option of multiple grades of planetary roller screws and with an option for an ACME screw. These multiple grades of screw type allow you to select the configuration best suited to your application.
The K Series provides an ideal replacement for pneumatic cylinders, with dimensions and form factor consistent with ISO Metric pneumatic cylinder specifications.
The availability of high performance planetary roller screw drive allows the K Series to also replace hydraulic cylinders and provide a solution that offers superior life and performance to ball screw actuators.
Four product performance levels are available so you can choose which option best suits your application and budgetary requirements:
KT Series incorporates Exlar's highest performance precision planetary roller screw. The KT option is perfectly suited for high load and high cycle rate applications where maximum life is required.
KX Series provides a high performance planetary roller screw for performance far superior to competing actuator technologies. The KX is an ideal choice for demanding applications in industrial automation, mobile equipment, process control and others.
KM Series gives you the benefits of planetary roller screw technology over ball screws at a very economical cost.
KA Series actuators are constructed with an ACME screw for low duty cycle applications with 2.54 mm and 5.08 mm leads. The KA Series can provide non-back driving solutions with a 2.54 mm lead. The KA Series is an excellent choice for applications that position and hold a load, or need effective low duty cycle electro-mechanical motion.
