Treadmill motor is 180V DC, how can I reduce voltage from 240v?

I have just done it with this off e-bay https://www.ebay.co.uk/itm/144092505139

HHD6-G 1200W Input AC220V 5.5A Max Output DC 0-220V Motor Speed Controller 50Hz £30.44

It works a treat stripped it out and fitted into my own case with power in and power out to motor with the pot I get the veritable speed.

Thanks Phill, how do you regulate it so it cannot output more than 180V?
