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.

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 ...

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 ...

Power and torque are concepts we all know and understand, right? Well, not everybody can accurately describe the difference. Imagine, for a moment, you're stopped at a red light when a slammed '06 BMW ...
