Hello
I am new to this forum and need your support,
I bought 72v 50Ah electric chinse Quad which orignlly came pre installed with Votol EM -50s & 1000w motor
I decided to upgrade the controller to EM-150 & didnt get the power I was hoping for.
Next step I ordered 2000w Chinse motor that at the begining controller setup didnt provide the power I hoped for which is spinnig the wheels from dead stop until I changed the deafault 'Flux Weakning' value fom 605% to 20%.
At the moment of change with wheels in the air I could applied full throttle to max speed but the RPM dispaly present up down flactuation (which was exist from first set up of this 2000w motor) so i couldnt tell if the RPM was as with the previous motor, However the when set on the ATV on the road the power was so strong & it blast me forward & the fron wheels almost fliped over had I not hit the brake with brutal force.
After that point I allways get 'Motor Hall' fault when reaching high RPM even if the wheels are in the air or on road the motor allways stall& after it stop I cant applied throttle again until it cut.
I checked the hall sensors, all 3 reach 3.29v when face the magnet then drop to 0, I even opened the motor to check for loose wires or soldering but everything was ok.
If I use the Low speed then the motor doesnt stop with the Motor Hall error.
Please advise if you have any Idea what is the problem
I will add pictures of my setup
Thanks
