Hi,
in 2017 i build a vector with Lyen 18Fet, motor MXUS 3000V3, with 18S LIPO 40AH (75.4v)
i use it about 50 cycles, and first issue is a sensor issue (too heat), i switch to second sensor set and add heatsink to motor, no issue during 1 year.
now since one month, regen issue with cogging during regen, and no amps, only few mA, (normal is up to 13A at high speed), (i've a wattmeter on my bike)
since last week, cogging at start is very important, it is very bad to start, and after reaching speed of 15km/h there is no cogging. But when i use @ high current/speed (Lyen setup is 60A Bat/120A phases), motor is cogging and controlleur cut off, need to power off and power on to use again but cut very quicly.
i use Ebike tester, for sensor, there are ok, and controller (led show OK for 120°), so I can not determine if the fault is on the controller or the motor ?
I've no other motor, and no other controller, i use them very little (rthe rear tire is not even 100% worn), I want to invest again in a controler or an engine but not the two right now),
besides that advise me you in controller ? (I would like sinus), Sabvoton 72150 or other ? (Kelly ?)
Same for motor : i think to Q3 3000 v3 50H because phase wire is very strong (mxus is too small and heat)
Thanks for your help to diagnose CTL or motor.
