[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 ...

The most common arrangement, which is used with only minor variations from small drives of say 0.5 kW up to the largest industrial drives of several megawatts, is the so-called two-loop control. This ...

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 ...

[Afroninja] is back with another great tutorial on basic electronics. This time around he’s explaining H-Bridge motor controllers and how they work! Even if you don’t have much (or any) experience ...

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 ...

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 ...

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, ...

The wide range of electric motors can be a confusing topic even without considering intelligent motor control. This brief overview is for those who think motors are only divided into two categories: ...

Microprocessor control lets variable-speed PMSMs save energy. Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, ...
