To produce a high speed, load-bearing linear actuator today, machine and equipment builders invest a good deal of time and money to design a mechanism with rotary-to-linear motion conversion. With the Allen-Bradley® LDAT-Series™ Integrated Linear Thruster, machine builders get high speed, load-bearing linear motion out-of-the-box, reducing design and assembly time by as much as 98%.
The device is a moving magnet iron core linear motor actuator with a built-in linear guide to carry a load. Its use eliminates the need for such power transmission components as couplings, gearboxes, belts, pulleys and other motion conversion mechanisms, saving energy by avoiding frictional losses attributed to these components.
The actuator suits applications with a high-duty cycle such as tray formers, cartoners, case packers, stackers, wrappers, horizontal motion conveyors and stretch-blow molding. The motor combines high velocity, up to 5 m/sec as well as high levels of acceleration. Peak thrust forces range from 187 to 4,306 N.
The LDAT thruster can be used with any Allen-Bradley servo drive, and uses the same innovative SpeedTEC® DIN connectors as the rest of the Allen-Bradley servo motor family, for a quick, secure assembly.
