Also, take a look at the Newton Tesla web site here:
http://www.newton-tesla.com/index2.htm
They are very helpful people and have kits especially for Myfords , a phone
call will put you on the right track..........
I bought my 'bare bones' Hitachi inverter from them years ago, and it's
still going strong and I'm about to transfer the Motor and Inverter to my
new (to me!) milling machine.
Very nice people to deal with.
Barry
PS - the motor didn't come from N-T, I got a good deal on that from my local
Electrical Wholesaler..

An IM B34 mounting is, essentially, a flange-mounted motor which may - but
not necessarily will - have feet as well.
An IM B3 mounting is a foot mounting, which is suitable for the Myford.
I would, however, suggests that a single-phase motor for use in your ML7
should have a resilient mounting, which - as far as my information goes -
isn't an IM B3.
For real flexibility of use, smoother running than a single-phase, more
starts per hour capability and other functionality (such as soft-start and
dynamic breaking), I'd always recommend 3-phase/Inverter over 1-phase,
irrespective of more cost for the former.
Since you already have a 3-phase motor (assuming it can be connected in
delta) you'd only need the Inverter. Judging by the price that Home and
Workshop Machinery are charging for new Brook-Crompton motors to suit
Myfords, the inverter is about the same price.
Of course, you can buy cheaper motors - - - - - but quality ? I suggest you
check some manufacturer's web-sites. Try :-

Subject: [modeleng] Myford ML7 motor replacement
Hello everyone,
A quick call for help please - I have finally decided to pension off the old
washing machine motor that my second hand ML7 came with. Although I would
like to put the original 3-phase motor that it also came with back, it would
seem that I can buy a new single phase motor cheaper than I can a 3-phase to
single phase inverter, or even the bits to make one, but I need to know what
foot the motor should have however. I can have either a B3 or a B34,
apparently, whatever that means ...
Would someone please be kind enough to steer me in the right direction and
let me know what I should be buying?
Thanks in anticipation,
TonyW.
