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 ...

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 ...

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 ...

Tutorial on ac-motor control based on Clarke and Park transforms. Concepts are presented in stages from top-level through deeper levels of detail. Regardless of their primary field, sooner or later, ...

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 ...

Over three decades ago, real-time software was predominantly written in assembly language or a combination of assembly and the C programming language. Even today, certain digital signal processing ...

Engineers rely on motion-control devices to improve efficiencies and production rates on automated factory floors, or at least maintain them. One family of such devices, stepper motors, is widely used ...

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 ...
