Hello there. I am using a scramboard, 54.6V 13s battery and a converted alternator as FOC motor on a motorbike.
I have no hall-sensors (yet) and no temp probe(yet).
It works pretty well @ 100amp motor current and battery current. 45kmh . Good torque. Good braking.
But it boggs at startup.
Rpm is limited @ 35k erpm , but is dependent on the rotor current. How can up this?
More important : when going uphill, after 30seconds to 1 minit, the bike slows down. Current goes down to 30amps.
Battery voltage stays over 50v. No overheating of controller or motor. No errors reported.
When i stop for a few seconds , power is back.
Any ideas?
I tried normal firmware 412 ant no-limit-firmware.
