VIFERR Variable Frequency Drive 2.2KW 220VAC Single-phase Variable Frequency Drive VFD Speed Controller for 3 Phase 2.2kW AC Motor

I purchased this to use with a 3 phase 1 HP TEC motor I have. It was to replace the one on my old milling machine which is making awful noises. By using a 3 phase Motor with this I can have variable speed on the mill without having to swap pulleys. A VFD (variable frequency drive) also retains the torque on the motor when changing speed. I have already got 2 of these units, one on my Myford Lathe and one on my CNC spindle and have never had a problem.Unfortunately since purchase my old Startright 352 bandsaw motor packed in last night so the mill project will have to wait and this will now be fitted to the bandsaw instead, that will have the advantage of giving me variable speed so with the right blade I should be able to cut metal as well (always try to look on the bright side when it gets expensive). Just means that I will have to buy another (and a motor) when funds permit for the mill.It is important that you get a shielded 4 or 5 Core 3 phase cable to connect the vfd to the motor (std mains cable from vfd to socket is fine) or you can get signal interference causing the motor to act up. This I purchase from a well known auction site for about £4 per meter delivered.

works well and easy to understand and set. A lot of electrical noise and can interfere with other electronics

Good item and works well but instructions to program are virtually impossible to understand or follow due to the lack of written instructions. The only way it was possible to program was to reference YouTube.

I had to buy one of these inverters following an error done from chinese supplier on one of my machines.It was too expensive to change motor so I opted for one of these. Good price, fast shipping (i chose the fastest delivery and it was indeed) and the product, despite being chinese, is of very good quality.Worked wonders and its easy to wire and operate.

It came well packaged and secured , good safety instructions , build quality is good , everything well labelled and straight forward to connect.Improves heat dissipation, and safety working in damp , humid, dusty conditions, it has good inbuilt safety features too.It's more compact and lightweight than i was expecting, instructions make it easy to set up and connect safely.Good value with the current discount, a good option.

It gives you accurate reading. Quality of the item is good.

I use one for the vehicle lift and the other for the compressor. 2.2kW engines in both cases. Make sure you set it up right and it works perfect
