I would like to use a 2018 LMX Motor for my Etricks R01.
As a controller, I have a Kelly KBS 72181E.
The problem is:
The Hall sensors make short pulses before and after the main pulse. As a result, it runs rough and needs too much power (4-5A at 72V at full throttle without load) and fluctuates in the speed while I give constant throttle.
Tested / made so far:
- flawless function test with Infineon 12 FET controller
- All 36 combinations Hall / Phase tried.
- Auto tune
- Diodes in the yellow, green, blue Hall sensor line (tip from the ES Forum works fine: the engine runs better/smoother than before)
Any ideas what I can do?
