Ebikebert
100 W
hey guys today is a sad day for me. I started today riding my e-bike for the first time after many hard working months. It was fun while it lasted but i knew there was something wrong with my setup. Here is my setup list. I have a 1000W yescomusa motor running with a 9 fet 72v lyen controller running off of some fresh 20s 4p Samsung 25R batteries. I knew there was something up when it was running a top speed of only 30.8mph where it should be hitting 40 mph easily on full throttle. I checked the voltages coming from my throttle and it measured.81v at rest and 3.52v at full throttle. So i said to myself perfect! Its just the throttle because i know the voltage between the ground and signal wire are supposed to go up to 5v for full throttle. HERE IS WHER SH*T WENT REALLY WRONG so i had a dc-dc converter and set it at 5v to use as the full throttle value for the controller. I had everything hooked up and powered on my bike. i proceeded to pull out first the signal wire and the motor went full throttle without me realizing for about 2 seconds and then stopped on its own. My motor wont spin now and something inside my motor has shorted because it is now hard to pedal with the motor now where it was easy before. So now im stuck with the wrong throttle for the job and a shorted motor (I think).
Do you guys think i blew a hall effect in the motor or something like that? thanks I really need your help guys I have been unsucessful on finishing my build for over two years!
