Hello everyone.
I have an electric brake on a truck and I would like to make a dynamometer for engines. Has anyone done something like this?
And is there software to manage the brake and then get the power curve?
Regards.

Hi, you have an eddy current brake? Lots of folks make their own dynos with them.
For a roller dyno the most challenging is to source a suitable roller. I recommend asking in DIY Dyno on Facebook. There are lots of knowledgeable people there.
For an Engine dyno, the challenges are different. You need to gear down the brake, since they have lower max RPM than the engine (typically). A belt works. You will also make sure to have enough capacity in the brake, since they get hot after a little while and hot = weaker for eddy brakes (in particular if the coil wires are aluminium, which is the case for most truck brakes).
YourDyno has what you need on the instrumentation/software side. This kit can do it: Chassis Brake Dyno Kit - YourDyno.com
