AutomationDirect has added a high voltage AC drive and compatible high torque motors to its stepping system motion control product offering. The AC stepper drive is powered from 90 to 240VAC and is ...

Greater use of robots in the world of automation is bringing about higher productivity in manufacturing, as well as lowering costs. To meet those objectives, robots must have faster response times as ...

PFT Series AC hipots test medium and high voltage electrical apparatus: vacuum bottles, hot sticks, motors & generators, rubber gloves, iso-phase bus, switchgear, and other loads requiring AC ...

Isolation is a means of preventing direct current (DC) and unwanted alternating current (AC) between two parts of a system, while still allowing a signal and power transfer between those two parts.

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

Since AC induction motors have been established as the preferred choice for industrial motors and the need for reduced power in all aspects of design is ever present, the efficiency of these motors is ...

For motor applications, engineers have several options at their disposal. Typically, engineers can choose between direct-current (DC) or alternating-current (AC) motors. Machine Design has covered the ...

Utility power plant generators are usually designed for a power factor (PF) of .8 to .9. If demand-side PF is lower than the designed PF, the generator current will rise above the equipment's rated ...
