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 ...

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, ...

Controller manufacturers are improving features such as motor protection and brushless dc commutation. One operation of all motors, whether powered by ac or dc, calls for a controller. The simplest of ...

The principle of vector control of electrical drives is based on the control of both the magnitude and the phase of each phase current and voltage. For as long as this type of control considers 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 ...

In today’s fast-paced industrial landscape, efficiency, sustainability, and performance are essential. One technology driving this change is low-power AC drive technology. Variable frequency drives ...
