Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

Motors account for at least half of the energy consumed in the U.S. Selecting the right control method for an application lets the motor run most efficiently while maximizing torque and overall ...

Bipolar stepper motors provide precise position control while operating in an open loop. Industrial automation applications—such as robots and processing and packaging machinery—and consumer ...

In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...

Stepper motor systems are highly efficient when producing torque, but lack operational efficiency when not producing torque. Applied Motion Products offers insights on how to make a greener and more ...

Network analysis is a powerful and well-established method of characterizing and optimizing a control system. [1] Unfortunately, making a successful measurement can be difficult and frustrating ...

Open-loop stepper motors have held a prominent position in automation applications over the years due to their simplicity, excellent positioning, and low cost. However, as manufacturers utilize faster ...
