Next is the H-bridge, which resembles an H (Figure 2), which is used typically with a brushed DC motor. In addition to run, coast, and break operating modes, it can also reverse a motor. Simplified ...

[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 ...

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 ...

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 ...

A motor protection relay safeguards electric motors by detecting thermal stress, phase imbalance, stall, and abnormal ...

Regardless of their primary field, sooner or later, most designers have to deal with motor controls. Broadly speaking, there are two methods to incorporating these components in your design. First, ...

One of the challenges that face motion-control engineers is how to properly select a motor. If the motor is undersized or too small, it will not handle load. If the motor is oversized or too large, ...

Energy conversion efficiency has always played an important role in electronics design, and in the case of electric motors, the conversion takes place twice: first to create the electricity needed to ...

As electrification reshapes the transportation industry, the use of smaller, denser, and more efficient electronic and electrical (E/E) assemblies is intensifying the need to manage heat stemming from ...
