VFD 4KW 5HP 16A 220V Single or Three Phase Input to 3 Phase 0-3000 Hz Output Variable Frequency Drive Control Inverter for Spindle Motor CNC Speed Control

I am in the UK and needed to convert my 1974 Colchester Student lathe from 3ph (2.2kw) to run off 240v 1ph. I chose the 5hp (4kw) version Mollom VFD as the lower power ones were not available at the time. I have wired it so the lathe control stop/start/reverse go through the inverter to control it as original lathe set up. I emailed the seller and they sent me the parameters. I did have questions and the tech support (which I assume is in China) was answered with expert knowledge within 12 hours so next morning a reply was waiting. I am a professional user and wanted to use the lathe for a couple of months and can report no problems what so ever. If your converting your 3ph spindle machine then I highly recommend Mollom for the VFD. Due to the higher KW rating I assume I was able to set the acceleration and deceleration times to 3 sec and 2 sec respectively without any over load problems. A lower kw VFD may well have needed a braking resistor wired in. As a cautionary note, not all 3ph motors can be converted to 1ph VFD so do your homework first.

Product works great for my needs and the support team was more than helpful getting it set up for my application.

Funciona muy bien, buena respuesta por parte del vendedor

Came on time and so far it’s working good. Very easy and convenient to install.

I'm only using this as a single to three phase converter, not using any of the speed control features. I originally bought a DPS converter but turns out they don't work for a lot of motors since they don't give full voltage on all three wires. The Mollom does and works great for my application. The downside is it's not plug and play. Tech support is great, I just emailed them my motor specs and they sent me the settings and it works great. The manual is lacking and so you pretty much have to email tech support, but I'm really happy with it.

Forget the Digital phase converters (DPS) and the other VFD’s on the market. Unless your application is very basic, and you are very handy with electrical wiring and programming, you will need assistance. There are very few companies as prompt and helpful as Mollom. No only do they answer the same day(time difference allowed for) they have a clear and comprehensive understanding of what you are asking. They go above and beyond to be of assistance and are very helpful and professional. I have rarely meet any Company willing to take this care and attention to after sale’s assistance for products in this price range.Local USA VFD’s are significantly more expensive, and they insist an electrician install them. With Mollom, you have assistance all the way.Great company, the best factory assistance
