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 ...

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 Kinetics announced that it is “now negotiating with several drive makers who are potential licensees,” says Dr. Neil Singer, president, AC Kinetics, Inc., an advanced engineering solution provider ...

Early incarnations of the electric motor first appeared in the 1740s through the work of Scottish Benedictine monk and scientist, Andrew Gordon. Other scientists such as Michael Faraday and Joseph ...

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 ...

The recent push to make everything smart or connected has led to some interesting evolutions in manufacturing. Application and infrastructure divided the use of electromechanical and fluid power.

Special algorithms make ac induction motors respond like variable-speed dc motors for fast PID control. Synchronous dc motors often top the field in high-performance motor controls. This group of ...

When the Washington State Ferry System selected a synchronous, variable-speed AC motor with a cycloconverter drive for the propulsion system on its three new Jumbo Mark II ferries, the ships became ...

The AC induction motor is often referred to as the workhorse of the industry because it offers users simple, rugged construction, easy maintenance, and cost-effective pricing. These factors have ...

Choosing the right motor and VFD type depends on a variety of factors; however, it is necessary to analyze how the motor changes when the speed is reduced. The experts at eMotors Direct outline ...
