Looking for a Closed loop brushed motor controller

[Draco]

Hello
I was wondering if anyone knows of a closed loop dc brushed motor controller that is good to 20-30 amps intermittent. The motor is a DC brushed motor that is called a servo disc and has analog feedback from the motor itself, 0-12volts dc and the motor runs from 0-40 volts or so, it's running a band saw. I was hoping to find a driver that can do constant speed with the feedback voltage provided by the motor. The band saw was a trash find and was able to rebuild part of it and uses an external motor that runs it way to fast to cut aluminum with. I want to see if there is anything cheap that can do constant speed.
Thanks
Draco

If you're open for DIY you need just PWM generator at 555, a MOSFET and a few passives.
