Insistent demand for energy-saving industrial and home appliances has recently escalated because of energy and environmental matter and the necessity to comply with new energy consumption regulations.

Variable frequency drives convert ac power to dc and then reshape that current to control ac motors. All types control speed by varying current frequency, but one subtype — flux vector drives — uses ...

It shows the vector motor control and one the of best sensorless vector control frequency inverters. Vector control is one of the most popular electrical motor control modes in electric industry that ...

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 ...

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 ...

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, ...

Motors account for at least half of the energy consumed in the U.S. Selecting the right control method for an application lets the motor run most efficiently while maximizing torque and overall ...

Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...
