The Allen-Bradley PowerFlex 70 AC Drive is a proven solution designed for demanding industrial motor control tasks.

This document written by Steve Bowling, Application Segments Engineer at Microchip Technology, discusses how motor works and describes the AC induction motor, variable-speed ACIM control, and FOC.

Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

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 ...

Single- and three-phase alternating current (AC) motor speed can be controlled by controlling the frequency of the voltage coming to it. Motor speed has a lot to do with the capacity of refrigeration ...

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 ...

For the PDF version of this article, click here. More than 80% of the motors bought each year continue to be low-cost single-phase ac motors. Because these motors are not very efficient when ...

Choosing the right motor and VFD type depends on a variety of factors, however, it is necessary to first look at how the characteristics of a motor change when the speed is reduced —Sponsored article ...

ON Semiconductor has introduced a motor development kit for motors up to 4kW, and soon to 10kW. “In order to improve efficiency, ac induction motor drives designers must understand how these and other ...

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...

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 ...

AC Technology, a member of the Lenze Group, announces the release of its SMVector Drive. With its price, its flexibility and a power range of up to 20 Hp, the SMVector drive excels in environments ...
