[modeleng] Re: Myford ML7 motor replacement

Tony

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.
