[Editor’s Note: This is part 2 of a two-part series. For part 1, go to http://bit.ly/gSjOBf.] In the motor control system, current is a common item to be measured ...

Today's motors are increasingly driven via electronic controls, which offer better control of speed, position, and torque, as well as much greater efficiency, rather than via direct connection to ...

This fall, the SMMA Motor & Motion College will offer three motor control courses. Topics to be covered include the Basics of Brushless DC Motors, Basic Motor Theory, Operation and Application, and ...

The NEC defines a controller in a few different ways. In Art. 100, a controller is described as “a device or group of devices that serves to govern, in some predetermined manner, the electric power ...

Monitoring takes the form of sensors and intelligent devices connected to a digital processor. These monitored values are used for computing and then controlling some sort of real-world action. Many ...

Using pulse outputs from a PLC is a cost-effective way to get simple motion. Most, if not all, PLC manufacturers provide a way to control servos and steppers using a pulse train signal. So when a ...

When you get the call, “The motor won’t start,” you’d best have a logical and systematic plan in place to approach the problem. “Easter egging” just doesn’t work unless you happen to be very lucky!

Classic radial gap, stacked lamination stators. (Shown with and without windings.) As we look at catalogs of electric motors, we find them classified by power, speed, and torque. To a large extent, ...

While current control and PWM switching play the most direct role in driving brushless DC motors, the motion profile and ...
