The basics of power supplies in industrial machinery

Although power supplies just keep getting better, these well developed devices still must be properly specified and connected.

Voltage Main Nav

A variety of power sources are typically required to operate industrial machinery. This includes the plant line side ac voltage down to the electronic devices—power supplies—used to convert the ac to dc voltage. Not only is the type of power supply important, but the requirements for the application must be understood. There are many power supply configurations available that have made their way into industrial automation such as the ac adapter to power a laptop computer or monitor, the benchtop power supply for precision testing and dc/dc converters for specialty purposes such as providing lower voltages from a bulk supply. However, unregulated, linear and switching…

How to size a motor

Calculations, advice and formulas for ensuring you have the right motor for your application.

A Control Design reader wrote to us: "The multi-station dial indexers we build are in multiple diameters and different cycle rates. We have one basic design that is customized based on the needs of the application. How can we be sure we’re sizing the right type of motor correctly? The tables’…

  • Deterministic variants of Ethernet allows real-time machine control

    By Dan Hebert, PE, contributing editor

    Ethernet has taken over industrial automation communications in many areas, but its lack of determinism has limited use in many real-time control applications. Suppliers are addressing this issue by modifying Ethernet to add determinism, and a new Ethernet time-sensitive networking (TSN) standard…
