What brand of frequency converters are widely used in China nowadays?
Thread Content
My company has been in operation for over a decade; we use around 100 frequency converters, ranging in capacity from 0.5kw to 90kw. Most of these are used for motors in industrial and mining applications that require high torque. The Anbangxin inverters I used before were said to have German-made chips, and they worked fairly well in practice… Nowadays, I have to repair around 20 of these units per year. But once the manufacturer releases a new model, it becomes difficult to find spare parts for the older models; in such cases, it’s not possible to repair them and one has to replace them instead. Which brands are currently widely used and offer reliable quality? Mitsubishi? Still ABB? I think if there is a high inventory, it’s easy to maintain both in terms of repairs and replacement parts.
ABB is durable, but it seems to have no Chinese menu.
Mitsubishi is widely used here, and its quality is pretty good
ABB, Siemens, Schneider
For mainstream frequency converters, Mitsubishi, ABB, Siemens, and Fuji are all good options; they should hold up fine for a few years
ABB, right? It has a high market share and reliable after-sales service.
