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 ...

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

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 ...

Every day engineers design products that employ single-phase induction motors. Speed control of single-phase induction motors is desirable in most motor control applications since it not only provides ...

Control systems are exactly what you think they are: systems designed to control something. Perhaps a better way to put it is systems design control the behavior of something. The term “control ...

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 ...

There are definitely some hefty words in the title but Texas Instruments (TI) has brought something new to the motor control table with its InstaSpin-FOC (field-oriented-control) solution. It is a ...
