A rather uncommon chinese fat ebike came into my hands.
It has a 750 or 1000w rated motor (not sure which) and a S900 display. When in throttle "on" mode, the display shows "8" in the error field - the manual says hall error - check hall sensor. It wont display speed either. It pulls strong and will take off from a dead stop.
I don't know if the S900 was programmed correctly, so i wanted to try that first rather than pulling the rear wheel and opening the motor (I'd need to buy a gear puller too first i guess).
Problem is, I need to program in the number of motor magnets into the s900 display.
Is there a way to determine the # of magnets without pulling the motor apart?
attached are some pics of the motor. The manufacturer of the bike (Sobowo on alibaba) shows bikes with several different motors so I have no way of knowing what this is. There is a number etched on the motor: ZC61010310 - maybe someone knows a bit about these?
Side question: how do i find out the real power of this motor without doing a dyno test?
