Energy efficiency is for more than just motors. Here are some mechatronics companies making sure you get more bang for your buck when it comes to your power bill.
Electromechanical rodless linear actuators can offer better load handling in smaller spaces than rod-style actuators, but realizing those benefits requires careful attention at the specification level. Whether you are replacing a failed actuator, looking for better performance or building a new application from the ground up, success depends on how precisely you specify application requirements.
Medical imaging equipment, water handling systems, conveyors, robotic systems and rotary and linear actuators are among the many devices that may be fitted with electric friction brakes to hold their loads in place when the power is off or disrupted.
Smart actuators bring big benefits to utility and other off-highway vehicles
Automated production of large objects such as auto body prototypes, boat hulls and surfboards traditionally requires computerized numerical control (CNC) systems costing nearly a million dollars. Thomson Cuts Costs and Production Time for Autoscale Inc.

In today's highly competitive world, the better someone understands the advantages and benefits of direct drive technology, then the more they will have an advantage in machine building, giving them an edge over their competition.
The Swiss Army Knife of PT Components.
The U.S. Space Shuttle fleet was originally intended to have a life of 100 flights for each vehicle, lasting over a 10-year period, with minimal scheduled maintenance or inspection. The first space shuttle flight was that of the Space Shuttle Columbia (OV-102), launched April 12, 1981. The disaster that destroyed Columbia occurred on its 28th flight, February 1, 2003, nearly 22 years after its first launch.
How would you compare the efficiency and capabilities of hybrid stepper motor actuators vs. can stack stepper motor actuators?
During the qualification campaign of the NIRSpec (near-infrared spectrometer) instrument mechanism, the actuator could not achieve the expected lifetime that had been extended during the development phase. The initial design could not be adapted to the requested number of revolutions during that phase. Consequently the actuator needed to be modified so that the function of the mechanism would not be endangered or, by extension, the overall function of the NIRSpec instrument. The modification included a change of the overall actuator designâ”internal dimensions, tolerances, materials, lubrication and assembly processâ”while keeping the interface to the mechanism, mass and function.
When the need arises for linear motion or positioning, there are many choices. One can use an Acme screw, ball screw, rack & pinion, or belts. The cost of a linear motor solution is generally greater than a mechanical linear product, but when one needs highly accurate, repeatable, high-speed motion, then the answer may be a linear motor.
Improving System Performance One Application at a Time. PTE recently caught up with IKO, Rollon and THK to breakdown the basics in linear motion rolling guides.
