Tromox Mino

[vlad_vy]

I wrote down a reminder to cut the wire to pin 30 of the controller connector, but I still forgot about it.

Today I cut this wire, as expected nothing has changed, everything is working. In a normal situation, this wire does not affect anything, but in case of a short circuit in electronics or wiring, its presence is dangerous by wiring fire and damage to the controller, since it shorts the fuse 10A 60V and the short circuit current will go through the controller, from the terminal +60V of the controller to pin 30 of the controller connector.

So, it‘s time to take on that RS485 protocol, don‘t you think?

[vlad_vy]

The RS485 is phisical level protocol. Thats about higher level protocols:
* LanDrive
* ProfiBus DP
* ModBus
* DMX512
* HDLC
* IEC 60870-5

Sorry, I‘ve meant: decoding the transport protocol and the messages on the RS485 port. I could not get around to it because my 18-month-old is keeping me busy…

I'm afraid I can't help with that, right now I have two RS485 devices only, a battery and an anti-theft alarm. The dashboard and VCU have already been removed. The controller has been replaced with another one.

Hi vlad_vy

Did you buy the fenders, or is it something you made your self?

[vlad_vy]

I use fenders for 47cc и 49cc Minimoto Mini ATV /QUAD/Dirt Bike. And cut these fenders for my needs. Next, clue with 3M adhesive tape (3M Automotive Acrylic Plus Tape). Additional chain guard is cut out of a plastic stationery folder.

The factory Tromox Mino is designed for a speed of 46 km/h. Motor Kv=35.5. With the help of the stock controller, it is accelerated by 10% (High Speed Percent = 110, Flux Max. Peak Current = 10A), up to 50 km/h. Without acceleration (High Speed Percent = 100): Max speed without load = 55 km/h, speed slip = 16%, 55 * 0.84 = 46.2 km/h. The maximum speed you can get with another controller (High Speed Percent = 130, Flux Max. Peak Current = 30A) ≈ 58 km/h. Max speed without load = 69 km/h, speed slip = 16%, 69 * 0.84 = 57.96 km/h.

The last setup is the best of everything I've tried. Controller LBMC072122SHK3AP-M29 (LBC100.029D).

Changed from the factory settings of the Tromox Mino controller:

Motor Design RPM = 2120 (2520*0.84=2117)
Motor Max. RPM = 2520 (55 km/h)
Speed-Loop Mode Setting = Soft
High-Speed Percent = 130 (55*1.3=71.5 km/h) (55*1.3*0.84=60 km/h)
Middle-Speed Percent = 56 (33.8/(55*1.3*0.84)=56.3%) (30 km/h / 63V * 71V = 33.8 km/h)
Low-Speed Percent = 50 (not used)
Flux Max.Peak Current =30
