The Advantages of Modern Electric Actuators

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.


Bring New Life into Electric Control Valve Actuation

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.


Comparing T-LAM (Segmented Lamination) Stator Technology to Traditional Brushless Motors

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.


Electric actuator technology prospers in production fields


Electric actuators aid design of medical device

Clean operation—operating without the need for fluids or ancillary equipment—is one of the major advantages of electric actuators.


Electromechanical Actuation ‐ A Benefit for Military Vehicle Design

With increasing regularity, industrial motion control has moved and is moving away from hydraulics.


Electro-Mechanical vs Pneumatic Actuators

Weighing the options between the use of electro-mechanical or pneumatic actuators in machine and systems design.


Electromechanical Actuators in the Automotive Industry

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.

How To Create Nothing – Faster

Longer tool life is an added benefit.


Linear actuator simplifies machine building

Purchase and assembly of multiple components are rendered unnecessary because this actuator combines servo motor and planetary roller screw m one compact unit.


Linear Actuators Support Weapons Elevator

Among the most vital material handling systems in use today are those that handle weaponry for the armed forces.


Medical Motion: Electric Actuation

Electric actuators offer diverse integration capabilities, such as combining the motor and actuator, delivering a more compact package while reducing spacing requirements.


Motion Gets Smarter with Integrated Actuators

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


Optimized Stator Design

Segmented lamination technology increases motor efficiency, power, and compactness.


Recognizing Motor Temperature Sensor Limitations

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


Revised Duty Cycle Calculations Using the Four-Parameter Thermal Model

High-performance motion control demands compact and economical servomotors.


Roller Screw Actuators: Benefits, Selection and Maintenance

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.


Sizing and applying roller screws

How it works. Roller screws convert rotary motion into linear motion just like acme and ballscrews.


Smaller and Mightier Electric Actuators Help Advance Medical Applications

Technological advances and changes in environmental, safety, and ergonomic requirements have increased motion control options and their capabilities.


Smart Redesign with Peek Keeps Neutron Source Cool

A single-piece machined PEEK cooling jacket replaces a two-part polycarbonate component in a high-energy neutron-beam source.


Why All Exlar SLM Servomotors Have a 50°C “Hot Spot” Temperature

Although the “ideal” servomotor doesn’t exist, the servomotor(s) is often commanded to output its maximum “Peak” torque for the longest possible time.


Why the Exlar T-LAM Servo Motors have Become the New Standard…

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.


Why Servomotor Temperature Sensors Can Give Misleading Readings

Conventional thermal models can be inaccurate enough to cause trouble when servomotors get pushed to their limits.
