When powering AC motors, the electrical supply can be at full power to run at full speed or at variable power to run at variable speed. Applications with varying loads benefit from the variable speed ...
AC motors are abundant in the HVAC industry. Every fan and pump application requires an AC motor. For efficient and reliable control, adjustable-speed drives are becoming a common companion for these ...
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 ...
Where K'EOO is the peak value of the back-emf waveform, measured phase-to-phase (o- o). Since in metric, the voltage constant KE (volt/radian/second) equals the torque constant KT (N-m/amps), the ...
The Durapulse GS20 Series of next generation high-performance variable frequency drives provides many standard and advanced functions in a compact reduced size unit. The new GS20X series of AC drives ...
AutomationDirect has added new NEMA 4X AC drives to their IronHorse brand of drives. These new high-performance VFDs support four control modes including V/Hz, slip compensation, sensorless vector, ...
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 ...
