Hi Peter, I live in Surrey UK. I have a Bridgeport series I with a 2HP motor. I purchased from Direct Drives a Speecom 7200MA plug and play inverter. I made no changes to the wiring inside the

Hey JAMES , I agree with you on the rivets , I've seen them used everywhere ,including the many places they really shouldn't be. Although the CENTER HOLE could be considered a modification to ASSIST

Hi Vincent, thank you for your reply but they are not, they are as in the image below with the hole in the centre, which I have never seen on drive screws. Always dangerous to be adamant but I am

I have been running mine (2HP series II without variable speed) on a 2kW VFD for about 18 years with no problems. It does present a couple of issues however. The Bridgeport FWD/REV switch must be

Are you sure these "pop rivets" are not drive screws? https://www.aircraftspruce.com/catalog/hapages/an535.php?clickkey=87329 Drive screws are often used to hold badges on equipment. Vince

Dave who runs Drives Direct is extremely helpful (if busy) and I have no hesitation in recommending them and their DPC products. An inverter only needs to be configured specifically to suit the motor

Thanks Andrew, I love AliExpress for stuff like this, carefully disregarding all the political issues! Bough a lot form there over the years and rarely been disappointed. I think that is probably the

Yes, as I said, seems to me to be the perfect solution. Ken G i l l e t t _/_/_/_/_/_/_/_/

Thank you again I will go through it this evening. I have already tried the 1.5 HP blown some fuses, the starting torque kills it. Plus stopping to change to higher speeds causes it to blow. It was

Morning James, Thanks for replying. No, just North of Oxford but that doesn't mean in a few weeks I couldn't take a trip North and I am planning on a trip at the end of June in any case. In the

I have sent you directly some more information on the direct drives approach. You may find that the current rotary will actually power your Bridgeport, with the limitations of maybe not achieving

Hi Clive, Yes you don’t want to fry the motor. I’m using a Chinese AliExpress VSD as per below. It only cost something like AUD$100 so I figured if it blows I’ll get another one. I got rid of

Thank you chaps, good to feel I am not entirely climbing a mountain on my own - it's been done before. Ken/John - never dealt with Direct Drives only Transwave , who have been very helpful. Like you

Exactly the same as mine Ken A great solution and uses little power then the DPC is ‘on’ but nothing is running. I often have had my shaper running while using the lathe……. A recent

Thanks Peter for the pics. Very helpful. As these motors are difficult to come by in the UK and have extended shafts to go into the gearbox arrangement the last thing I want to do is burn one out.

For quite a few years now I have been using a Digital Phase Converter from Drives Direct. <https://www.drivesdirect.co.uk/> A DPC is unlike a normal inverter in that it is not 'coupled' in any way to

I’ve got my workshop powered by an inverter system I bought from Drives Direct. This gives me a consistent 400v 3 phase. I can switch on any machine in my workshop and it starts, I can run multiple

Thank you for replying Peter. To answer your question:- My first option was take the 3 phase out of my garden that was ?8k of which ?2k was for the privilege of being connected - not doing anything

Hi Clive, I’ve done it on mine in Australia. 240 V in the VSD, original forward/reverse switch wired into the VSD via a cat 5 cable, can control the speed via the VSD or via the vary drive lever.

Why are you looking to run from an inverter? This setup should run ok from a rotary converter, assuming that the output is in the 380-440 range. Dual speed motors will not run successfully from just
