I tried to put my new unity from the raptor shop to work.
I had bench tested it on different motors and seemed fine.
So I decided to put it in my DB Coreflex build.
It has a 10s4p 30q pack.
Maytech 6354 170kv motors.
14/38 on 100mm Boas.
It had a Flipksky 4.20 dual in there and ran fine. But I thought it would be an upgrade to add the Unity instead.
I keep getting some weird values with motor detection. One vesc recommends 35 amps and the other 50…
I had turned both to 60 amps and tried to ride and got some weird stuttering on one of the motors.
Ohh. I’m running the unity on the vesc tool.
I reinstalled the latest firmware and have ran motor detection a bunch of times and have not gotten similar values for the motors.
I had bad resistance measurements on one of my original unities on delivery and was told to send it to bara and that it was a bad resistor. Maybe check random resistors values on the side that’s giving you troubles.
If you switch motors and it remains this way than something is wrong with the controller. One seems to be detecting double the winding resistance, my best guess would be a bad leg in the three half bridges. Check solder on bullets. Otherwise it could be the FETs in which case it would probably need an expert to repair.
I don’t think our old testing systems that we developed are being used anymore in production as they required some amount of maintenance and upkeep from people that knew what they were doing. This unit wouldn’t have passed our jig.
Just to put this to bed for anyone reading through, and for anyone who thinks the alie-express stuff is anyone except Jason, here is Jason linking all the stores he is falsely selling under and claiming they aren’t his (conveniently directing customers to them on the forum):
I’ve got the order, took just 12 days from submitting it. The Focbox’s pcb looks good to me, but I’d be interested in someone’s opinion who has actual knowledge on this.
I don’t have my motors yet so I can’t test it yet.
