A variable frequency drive (VFD) controls a motor's speed by varying the frequency of the power sent to it, instead of running the motor flat-out and throttling the output mechanically. That's the short version. The longer version depends on what you're trying to do with it, which is where the brand and series actually matter.
Variable frequency drives and inverters from a genuine spread of manufacturers sit in this category — Parker Hannifin and Danfoss make up most of the stock, with Hyundai Heavy Industries, Eaton, Schneider Electric and Johnson Controls filling in smaller, more specific ranges.
Danfoss VLT/FC-series and Parker Hannifin AC drives cover general motor-speed control across pump, fan and conveyor applications; the Hyundai Heavy Industries and Eaton stock leans toward larger industrial installations. We are not Parker Hannifin, Danfoss, Hyundai Heavy Industries, Eaton, Schneider Electric and Johnson Controls, and not an authorised Parker Hannifin, Danfoss, Hyundai Heavy Industries, Eaton, Schneider Electric and Johnson Controls distributor — we source and supply genuine Parker Hannifin, Danfoss, Hyundai Heavy Industries, Eaton, Schneider Electric and Johnson Controls stock through the open market and established distribution channels, with datasheets and certificates of conformity available on request.
Note there's a second, separately-catalogued Drives category elsewhere in our catalogue under a different parent hub — if you don't find the part you need here, it's worth checking there too, since the naming overlaps but the stock doesn't fully. This category sits under our broader Automation hub.
