MOLLOM 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.

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.

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.

Great cost effective way of converting single phase to three phase. I used this drive on a 3hp meat band saw. The drive worked great once the proper parameters were programmed. 4 stars because the instructions were not that great. An individual with no prior controls experience would have difficulty determining how to program this drive. Other than the poor literature this drive is great and would buy it again.
