Hi, I'm trying to use TDA 1085c for a 180V / 5A DC motor. Tacho is directly connected, inductive ~ 40Vpp, not sure if 8 or 16 pole.
First idea is to use a "standard" TDA 1085 PCB and add the rectifier bridge and a coil in series with the triac.
I have an old Minarik 133496 motor controller (NOS), without any documentation. In case someone has information, this will help a lot. I'm not sure if the Minarik is closed loop. There isn't any connector for tacho.
I'm very open for hints and good ideas, thanks in advance.

The MM300 series of Minarik drives were for DC motors and many models had a tacho input marked T1 & T2.

Thanks Max,
attached is a picture. That's all I have. Currently I'm working on a PCB for the treadmill regulator you post.
Have to do some recalculation, because it's for 230V. I'm using Target PCB.
Have a good day
