In a word - No.
Hmm thanks, no to which part?
In a word - No.
Are you one of those people who touch paint to see if the 'wet paint' sign is true? If a motor is smokes when running it's not a good plan to hope it heals itself while running it some more. At the very least it means the cooling passages are choked and need cleaning, or worse the winding insulation is breaking down.Up until now I had only seen it spin up for a minute or so, I turned it on and after a couple of minutes the motor started belching acrid smoke. Turned it off and checked everything was rotating freely which it was and tried it again, this time it ran fine for at least five minutes. Turned it off and then back on and the smoke started again was trying to repeat this a couple of times trying to find a pattern but the motor went pop when I turned it on one time .
I'm not sure I'd ever need variable speed but was just thinking if I got to get a new motor then maybe get one that's capable, I thought I'd understood that the VFD setup needed a 240/415 motor which I'd assumed could be run in either 240/415.
I'm not questioning the posts just trying to understand it.
As regards the belt tension, the rule of thumb I use on all belts, whether it be timing belts, fan belts or drive belts - you should be just able to twist the belt 90 deg on its longest section. Been using that method for years, taught to me by a very experienced mechanic and it hasn't failed me yet.
Don't restrict yourself to resilient mount motors.
Definitely do consider a VFD and 3-phase motor. Imagine getting out of a mini into a jag. They'll both get you down the road but the jag will do it quietly, with ease and a better quality of ride.
The resilient mount is to prevent vibration being transferred to the headstock.

Doesn't seem to be many suppliers for that type of motor. Here's one I found.

That type of motor will run on either 240V or 415V, but it requires a 3phase supply at either voltage. It won't work on 240V single phase.
Don't restrict yourself to resilient mount motors. You can fit a normal motor, put rubber pads under the mounting points. Strips of folded inner tube will do otherwise I have some shore60 rubber here I could cut some from.

and so- is your wallet
Haha no I try not to . . . I initially though it might have been caused by the belt rubbing on the casing where I'd realigned it so was checking that and trying it again. I took the motor apart this evening just for a look, I found that there was only 2 of the 4 studs holding it together and inside there was evidence that someone had been playing with the wiring previously, leaving it hanging on by a thread (picture 2), the inside was fairly crudded up so think it was probably due a new motor and maybe moving it had dislodged something, the inside coils were a little fried.
