The latest microcontrollers featuring field-oriented control bring higher efficiency to motor-control circuit designs in consumer ...

In this article learn about options for measuring current in motor control applications, the strengths and challenges of these options, and how using precision current measurement can optimize the ...

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 ...

The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

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 ...

Early VFDs used a simpler alternating method with single voltage pulses of varying amplitude, but this design required a controlled rectifier front end, generating a variable DC link, and it provided ...

Different types of motors need different types of drivers. Requirements for a variety of applications. Selecting the right motor driver is crucial to achieving the required functionality and ...
