VFD Recommendations

[Keith ChartersParticipant @keithcharters25446]

Hi, Our society has just been donated a Myford ML7 lathe. It is in working condition but, it is fitted with a 3 phase motor and we do not have the matching VFD! The motor has the following markings

kW 0.37, HP 0.5, RPM 1425, Volts 240/415, PH 3, HZ 50, AMP 2.0/1.2, Class B, DUTY CONT. We would like to source a suitable VFD for this motor so can anyone recommend one. TIA.

People rate Drives Supermarket who can apparently give good advice as well.  Or contact Newton Tesla for a turnkey controller. They normally supply with a motor but may be able to just supply the drive.

I’ve recently purchased from (Inverter) Drives Supermarket and was very pleased with the price (and advice) I received from them.

I opted for a 0.75kw TEC motor & matching Invertek Optidrive VFD. You sound like you just need an Inverter and checking the IDS website, a .37kw Inverter will start at about £85 (inc VAT) plus shipping.

However, I also ordered some other bits and pieces that IDS suggested I would need that I think you might also find useful.

They included a:

* A Control Pendant Kit – Fwd/Rev, Run/Stop & Speed

*  Mersen CMC 1 Pole Fuse Holder and Neutral Link for 32A barrel fuses

* 2m of 3phase ‘SY’ power cable

* Qty 1 Nylon M20 gland & Qty 1 ‘EMC’ metal M20 gland.

As I am busy with installing DROs at the moment (between decorating – my core mission atm) I’ve not been able to run everything up yet – but IDS provide both a VFD manual and a very clear “Easy Start Guide” as PDF downloads – so it’s very useful to be able to review these before ordering.

As far as I can tell, my VFD set-up is at least equal in spec to the ‘RTR’ offers available and over £100 less than one of those options (and less than half the price of the best known one). IDS is also based here in the UK of course.

If you email them, they may take a little time to get back to you, as the ‘support’ guy only works certain days but he’s very helpful. I sent a him a number of emails and he also called me back about one particular concern to talk me through it.

Regards,

Agree Inverter Drives Supermarket is the go-to one stop shop. It may be useful to buy a vfd from them that has their quick start guide as a pdf which makes control wiring and programming very straightforward, much more comprehensible than the manufacturer’s instructions.
