There's some DC drives here; https://www.inverterdrive.com/group/DC-Thyristor-Drives/?filter=Input|230V%2f240Vac+1ph
but you would need to find out if your motor is compatible.
Or maybe you could replace it with an AC motor and inverter drive.

The motor and controller was new 2000 - 2001 so don't want to change the motor just the controller box as it's big at 350 mm square, the supply to NECO box is 240-250Vac and I think the field supply to motor was 170 - 180Vdc

These Parker drives are quite good, this one looks like a candidate, but needs confirmed first.
