Possibly a proprietary Chinese one or a KB drive from the States, both are DC drives and very similar.

Hello John,thanks for your suggestions I will attempt to bring up some websites to have a look at, and see if they will fit in with the project.

You want to look at the threads on Chinese machines that have none 'pop' and find the suggested replacements.

I would suggest a KB Electronics drive. I fitted one to drive a 2hp DC motor (complete overkill on power, but the broken running machine it came from was £15) on my old milling machine. It has been very satisfactory. The model I used was the KBIC 240, good for 2hp but perfectly OK for smaller DC motors in the 180VDC or so range, if the appropriate "horsepower resistor" is fitted.

Received wisdom is that KB boards are better than Chinese ones.

Manual for the KBIC series is here, with details of the variants on page 8 and the horsepower resistors on page 9.

Details of suppliers can by found by clicking "international" at the top right of this page; when asked what country, specify England rather than UK, if that's where you are.

Usual disclaimer. Just a satisfied user.
