One of the challenges that face motion-control engineers is how to properly select a motor. If the motor is undersized or too small, it will not handle load. If the motor is oversized or too large, ...

Oversizing often happens when engineers try to match the inertia between the load and the motor rotor, so that they can tune the drive’s velocity, torque or position loop relatively tightly to meet ...

Servo systems may be direct drive or geared. For gearedsystems, the motor selection also involves a choiceof gear ratio. Figure 1 shows a motor connected to aload through an ideal (that is, no ...

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 ...

Is your company going green? Green has become the latest catchword to include actions such as recycling containers, reducing pollution output, and using Is your company “going green?” Green has become ...

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 ...

The International Electrotechnical Commission (IEC) defines a servo device as “an adjustable-speed AC power drive system that includes an AC motor integrated by feedback, a converter, and control, ...
