There's more to selecting a motor than meets the eye. Motors typically are grouped into three categories. General-purpose motors are designed around industry standards and feature standard operating ...

DC motors come in many forms, but they all have the same job: turning electrical energy (DC) into mechanical energy. Although DC motors have a common operating principle, many applications—including ...

Prior to the advent of the adjustable-speed drive (ASD), the polyphase induction motor operated as a constant-speed motor. Figure 1 shows the well-known torque and current curves versus speed for the ...

Unlike brushed varieties, brushless dc motors cannot be operated directly off of straight-line dc voltage. Remember, brushless motors use electronic commutation — so again, no brushes make physical ...

Frequently, when it comes to step motor selection, users will select a motor with the highest holding torque rating, assuming that it will give them optimal performance. However, it is an improper ...

When the U.S. Department of Energy (DOE) issues the final versions of it its long-awaited fan efficiency test and efficiency standards rules over the coming months, it will apply regulations to a ...

While software and other advanced technologies often capture the automation technology spotlight, the fact remains that not much happens in the manufacturing or processing industries without motors.

Motor selection is often a complicated process that takes a lot of work with various vendors. Groschopp engineers share knowledge and expertise about the motor selection process. Focusing on four ...

There are so many motors on the market today, from heavy-duty AC motors to tiny DC brushless and stepper motors. To use any of the motors users must have a full understanding of the application ...
