ABB Low Harmonic Drives

Harmonic distortion may disturb or damage sensitive equipment connected to the same circuit of a variable speed drive. Any distorted voltage and current waveform that deviates from the ideal waveform presents the potential to harm electronic…

Variable Frequency Drives for Wastewater

The flow and pressure of fans and pumps need to be controlled because water consumption varies during a day. The flow and pressure can be adjusted either electrically with variable speed drives or mechanically with fixed-speed solutions…

Difference From AC and DC Electric Motors

AC electric motors operate by applying alternating current (AC) power to the electric motor. The main parts of AC electric motors are the stator and rotor. AC electric motors stator consist of coils that are supplied with alternating current…
