First test run of the evant

And there it is:

It’s finally moving, powered by the electric motor!

I connected two of my emergency get-back-home ebike batteries of 48V 4Ah with a maximum current output of ~15A. That’s way to little to drive the QS-motor that’s in the Evant but still it runs. Don’t want to run it for too long though since I haven’t calibrated the valve for forward/backward motion and have to keep the P-brake engaged for the machine not to roll off the lift it’s on – which makes for quite some resistance in the hydraulic system.

The twist trottle is quite unusable in the Evant so I’ve made a quick hack for a system to control the RPM of the motor:

It’s just a 10k potentiometer and a switch. The plan is to set the RPM with the potentiometer and use the switch as an on/off switch to turn the motor off whenever it doesn’t need to run. That way I won’t need to adjust the RPM of the motor to turn it off, which I’ll want to do every time I’m standing still and not working with the machine.

Just made a quick and dirty connection to try it out and it works just as expected. So the next step is to make some kind of enclosure for it, put a better cable on it and a proper connector.
