3 Hp is a tad over 2.2kW, so it would run from a 13 amp plug – although starting under load might be interesting. That possible problem should be alleviated by running it on a VFD.

You can change it to run in delta mode

I prefer a slightly over-rated VFD. The motor may deliver 2.2kW but will not be 100% efficient. The VFD in the link appears to have adequate overload capacity. There may be cheaper options, but cheap price may mean less capabilities.

Mark, nice machine!
I have used a Bosch inverter from that company and have found them extremely helpful should your require assistance. Capacity wise your selection should be up to the job.

Mark, have a look at their Bosch Rexroth range cheaper as well, they can have a detachable control pad. I mounted the VFD in the cabinet and have the control panel mounted conveniently on the lathe. Takes up no room and the control unit is kept away from dirt (and swarfe!)

If you use decent equipment, ABB, Siemens, Jaguar, Mitsubishi etc.then this is entirely unnecessary.
It might be required if buying cheaper, lower quality drives but I only have experience with decent kit.

Hi mark

I hav the identical machine and converted it. If you use a vdf, there’s a lot of work needing to be done. The on off switch is built into the handle, and that has to be connected to the digital control. All the existing switch gear has to be ripped out as you cannot have any switches between the vdf and the motor. I set mine up to give a speed range of 30 to 65 hz via a pot mounted on the drip tray which is very handy giving a subtle speed range without changing gear, great when facing.

The pump which I no longer use works with a pair of capacitors to simulate 3 phase. I fitted a contractor as a master on off. It took a while to get  all this sorted, but it isn’t difficult as you deal with one section at a time and get that working then move on. It works well from a 13 amp plug. Most of us rarely force these machines, they are designed for heavy action and it won’t be often that you get even close to full power. In any case the vdf can be set to limit the maximum current supplied to the motor. The soft start is a great bonus. Give me a pm if you want more details

Edit.  The contractor I just switches the 240 v input to the vdf.  Your motor is dual voltage and it’s just about switching the wires over.  The lathe vdf conversion was a doddle compared with converting my Bridgeport!  

Edited By Zan on 16/11/2018 21:50:08 I have also fitted a vdf  and new motor onto my drill.  So easy to July to min speed when countersinking after drilling. Well worth the cost.  I’m a great fan of them one on the Myford as well!
