When it’s time to specify a high-performance motor that offers both precise positioning and cost efficiency, stepper motors offer many advantages over DC motors thanks to their brushless technology.

Servo motor sizing is the process of selecting the best motor for a servo application. Misconceptions engineers can fall into when selecting a motor include: sizing based on the horsepower rating of ...

A fundamental understanding of the speed-torque curve it the key to specifying a dc motor that will do everything it needs to do. Much has been written about the process of selecting motors for ...

As the cost of electricity goes up, energy efficiency becomes more and more relevant as a design parameter. This is even the case in motion/position control applications, where servomotors are widely ...

In a recent article, I wrote about step-motor system performance emphasizing key concepts that all engineers need to understand about this widely-used electro-magnetic-mechanical digital actuator. As ...

Selection of replacement motors is usually straightforward if the ratings are equivalent. Sometimes, however, a different type of motor is necessary or desirable. For success in these cases, it is ...

Electrical equipment often has at least one motor used to rotate or displace an object from its initial position. There are a variety of motor types available in the market, including induction motors ...

During a recent conversation with an experienced engine builder I realized we'd not recently discussed the importance of, reasons why and areas of concern about proper engine component integration.

There is no such thing as a torque motor. Any engine that has torque has horsepower. Any engine that produces 300 lbs.-ft. of torque at 3000 rpm has 171 hp at that engine speed.Anyengine—long stroke, ...

We try a Jeep Renegade with GKN’s latest self-contained electrified rear-axle with torque vectoring from a single motor. There's no better way to meter precisely the right amount of torque to each ...
