    Motor speed increase

    Thank you for your answer! The throttle issue you're talking about are wheelies? Or is there anything else that could go wrong? I'm concerned about the controller behavior as a 96v controller is probably made for bigger motor, will it be able to deal with smaller motor, different resistance...

    Motor speed increase

    Many thanks for your answers! It's really interesting. I think I will try 72V first and then 100V as I really need pretty high rpm. I know I won't double the loaded speed but the ultimate goal is to increase the max power rpm. And the autonomy is not a concern for me :) Ok, it's great to know...

    Motor speed increase

    Hello! I believe you can help me to answer one of my questions: I currently run a 1000w 48V direct drive hub motor with a 48V 1000 w controller and SW900 display and a 48v 1000W 10ah battery. I would like to increase speed of the motor by increasing the voltage with a 96V 3000W controller...

    Hub motor stops and go under high load

    Hello neptronix The 1.5V drop is an instantaneous drop on pretty heavy load yes, actively watching the voltmeter. The motor already had some speed. So your reply made me think I could test it on a bench to apply even bigger load. I just tested It (braking the motor to a complete stop on full...

    Hub motor stops and go under high load

    I just checked every connection from phase wires to throttle and none seems faulty. I can't make them any stronger. The problem could come from the controller itself that is made to run slightly higher power motor. Could it be that the controller detects too much resistance on the...

    Hub motor stops and go under high load

    I just checked the battery voltage of my 48V 1000W battery with the same setup and it only dropped from 52V to 50.5V. As it is still above the nominal voltage, chances are the battery is not the problem here. Plus I set the controller LVC to 30V(way below) I also tested my setup lowering the...

    Hub motor stops and go under high load

    My controller amp rating is 26amps, and max amp is 45 amps. Ok, I'll test with a voltmeter :) I guess you suggest it could be because of a voltage drop of the battery? Thanks!

    Hub motor stops and go under high load

    Hello ! I've got a problem with my motor that I can't solve by myself. It's a 350W motor that I run sensor less with a 48V 26 amps rated current controller with SW900 display. The battery is 48v and able to output 1000W My problem is that at around half speed and under high load, the motor...
