which motor

[robert ramage 1Participant @robertramage1]

Looking at exchanging my single phase motor on boxford lathe. Looking at newton tesla or transwave 3ph with inverter etc.. Has anyone had experience with either

I fitted a Newton Tesla to my Warco BH600G lathe.

Could never go back to belt changing now.

Did the same on my drilling machine.

The ease at which you can adjust the motor to get the perfect speed makes you wonder how you managed in the past.

Don't hesitate, fit one!

Robert,

You may find the thread "Myford Super 7 Single or Three Phase" dated 25/03/2013 of use in helping with your questions.

I totally concur with Ou above except that I fitted a Transwave outfit to my Warco. Wish I had done It years ago…..it has transformed the lathe.

[SpringbokParticipant @springbok]

Go for it but do not ask Warco how to wire it up they do not have a clue.
As above transformed my lathe and mill.

Fit a 3 phase motor every time, the motors are cheaper to make, simpler in construction, smoother in operation and cheap.Smooth like a V6 to a single cylinder engine. However, why pay through the nose for a package, VFD are very reiable, almost bullet proof.Buy a pre-owned VFD and with the motor,wire it up your self all for about £150 max. There are plenty of information details on how to alter the connections on a 3 phase motor, how to make a remote control station and how to alter the internal VFD programme.Its not at at difficult. If you look on Home Work shop there is a guy who often advertises VFD for sale, contact him, much cheaper than the package job. I was very fortunate,I bought three used VFD, at different times, from an auto jumble sale, all worked. I also bought second hand motors for £10 or £12 each altered the connection, down loaded the info, then made remote control box. It took time but saved a lot of money. My inverters were intended to be mounted within a control panel, so I got a sheet steel box from my usual supplier.I drilled a lot of ventilation holes in the top and bottom, at the top I fixed a piece of mesh and also made 4 spacers,

Using them, I bolted on top over the mesh and holes a piece of sheet steel about 20mm all round wide than the holes and mouted it, a bit like a Chinese Pergoda. The box with the inverter inside is screwed to the wall and I control the lathe,mill or drill via the control boxes, one at a time. My home brew set up has been working for the past 6 or 7 years. I have read about motors over heating when running slow due to the lack of cooling air and for a the first couple of years used to check them, never been a problem.

There was good article in MEW about making digital read out so I copied the ideal. I hope I have convinced you, tried my best.If you need any info send me an email.Ted
