New motor/esc for mill?

I used to work for Electricity North West ( the equivalent for the North West of England of National Grid for you).

The letter you have shown does not say that your electricity voltage was low.

It is a standard letter to tell you that your supply will be switched off while they do some work on the network.

In your case it says it is to refurbish the low voltage overhead line network to bring it up to modern standards.

So unfortunately, that is not the cause of your problem.

In your position I’d cut your losses and get a new 3ph motor and a suitable VFD. […]

Absolutely spot-on, Rob !!

Agreed 100%   Check out the plate on your old motor which should give you the Kw/Hp required.   Will give your mill many more years of life

Robcox made his suggestion before the OP confirmed that the mill already had a 3 phase motor and a VFD (both of which are now working) so its pointless going over old ground.
