Answers questions like: What are reasons one might have for choosing electric actuators over hydraulic actuators? and What are the challenges encountered with replacing a hydraulic system? as well as others.
Electric actuators based on servo-motor and roller-screw technologies can enable a responsive
and accurate electric actuator solution that‘s well suited for valve control.
T-LAM™ stators provide higher slot fill, >20-30% more slot fill in equal size traditional brushless motor stators which directly results in higher current rating, HP and torque.
Clean operation—operating without the need for fluids or ancillary equipment—is one of the major advantages of electric actuators.
Weighing the options between the use of electro-mechanical or pneumatic actuators in machine and systems design.
Linear actuation is a core technology for factory automation. Along with fluid power, (hydraulic and pneumatic), electromechanical actuators have become increasingly important in all common industries like packaging, food, energy, process control, construction and the automotive industry.
Purchase and assembly of multiple components are rendered unnecessary because this actuator combines servo motor and planetary roller screw m one compact unit.
The article “Linear actuators: smarter, more powerful” published in Design World highlights several of the new design enhancements available. Discussing the evolving trends in electromechanical actuators, they spotlight the best examples.
Among the most vital material handling systems in use today are those that handle weaponry for the armed forces.
Electric actuators offer diverse integration capabilities, such as combining the motor and actuator, delivering a more compact package while reducing spacing requirements.
Integrated actuators incorporating more advanced controls and broader network connectivity options are finding their niche in applications where an all in-one, actuator-motor control package fits cleanly into machine designs
An argument could be made that with the right sensors to protect a motor from overheating, the simplified model is acceptable. However, as we’ll explore in this installment, even this approach has limitations
The choice of hydraulic/pneumatic or mechanical actuators always depends on the application, but if application factors are equal, the roller screw actuator has some advantages.
Technological advances and changes in environmental, safety, and ergonomic requirements have increased motion control options and their capabilities.
A single-piece machined PEEK cooling jacket replaces a two-part polycarbonate component in a high-energy neutron-beam source.
Although the “ideal” servomotor doesn’t exist, the servomotor(s) is often commanded to output its maximum “Peak” torque for the longest possible time.
According to the U.S. Department of Energy (DOE) 63-65% of a typical manufacturing plant’s monthly electric bill goes to pay for all the electricity consumed by the electric motors.
