    HubMonster hits 107mph on the flats on page 6

    I go with big hub kelly motor, at 125V A123 battery and 800A kelly controller at 160kmh on the road, i read on CA 110V and 320A under load...crazy fast After some km motor go warm, not super hot... Seems this motor have so low impedance, generate very little heat for power you put inside, very...

    WONDERFUL John!!! Excellent results, i remember when i use the Kelly hubmotor too, and i have many many problems after 80Volts, because Kelly controller go in error for too much spikes current... After we try the 136V 800A controller and all go good with 120V lipo pack...the motor at no-load...

    Wires...

    Thanks to all boys, i understand perfect, i suppose for 300A 8AWG silicon wire (30-40cm) is possible to use without big problem. Thanks to all

    Wires...

    Thanks to jeremy and all for answer, i understand the wires temp goes up, resistence go up and loose energy in heat, but i try to understand if little wires limit the power, 300A can flow in a 12AWG like in a 0AWG? Little wires not limit the power the controller can output, or battery can output?

    Wires...

    Hallo Boys i have a question, many time i think, how much is important wire gauges for power setup... For example i always think, if i use 12gauge wire for 300A, yes this wires become hot, and maybe melt after 200C (silicon), but works, and 300A goes ok inside wires... But now i have a doubt, i...

    Monster motor

    Yes Doc, my ca is calibrated, the strange things of this motor is, at low speed, or from standstill, the power is not very impressive for a big motor like this, and drawing from battery is low too, but after 60kmh, start to pull very much and strong and AMP from battery goes up, i think this...

    Monster motor

    Some news.. Today i try kelly khb 90v 700a phase from a friend, with this beast of controller and with 20s 16a nano cells, motor go mooore strong and controller never cut out power :) But i see strange thing, i expect to see from 700a motor controller alot more amp from battery side, but i see...

    The power is never enough :-D:-D:-D I want to try more amp inside and taller gearing... Video soon

    Golden HPM5000B

    i hit 120kmh on greyborg for few second, i drive greyborg with 120V*150A=18KW :) Sure my bike with greyborg is very very light, this bike with Golden is alot more heavy :( If this Golden is really 5kw continous, i can put for few second 20kw inside, i hope...

    Golden HPM5000B

    mmm lower speed no good :D I go already at more than 120kmh with my greyborg motor, i buy golden for have more, not less! I think i can gear up, because i can go at the same speed on the road, that no load speed now (100kmh) I think i have enough torque for gear up if my load-noload speed is the...

    Golden HPM5000B

    Thanks :) Boys i want to make scream this motor, but i don't know how much power i can put inside, 300-400A phase? Gear ratio? Now i have 12-46, i want to try 16-46 for go at 140kmh no load, i hope motor have enough torque for push this gearing

    Golden HPM5000B

    Hallo boys new project start, yesterday we create new frame for a Golden HPM5000b motor,with a kelly kbl 150A phase controller, and A123 120V cells... The ratio gear is 12pinion 46ring on a 16" scooter wheel Ok the bike seems go very good,but i imagine alot more power on this motor, the bike...

    Boys i have found a friend with a Kelly KHB 700A phase 90V... I hope we can try this controller in the next week, maybe we can feel more power than kelly 400A from this beast of motor :)

    Please john when you find good strong controller for this type of motor call me!!!! :) Thanks very much!

    Monster motor

    I guess we call it a tie for now. I probably have a controller advantage with my Steveo special, and you have an advantage with the 65mm stator. Is it really a lamination stack of 65mm? If so, it must be a one turn winding. :shock: The guys playing with the ebike wind motors and big wheels...

    Monster motor

    Kelly can't help because the problem is not on the controller but in the low inductance of the motor, but ok i can go at 80-85V 240A, is good enough for me, maybe in future i can try to put more amp in the motor with bigger controller for more fast acceleration, but i understand is impossible go...

    Monster motor

    Ok Boys after 100000 try, i arrive at this conclusion, this motor can go at maximum of 80V, at this voltage and with little inductance on phase wire, i put out the controller 240A battery side, very good power on acceleration and 138max speed, if i try to use even little more voltage, the motor...

    Hihihihi thanks john i will think about this solution :D And if you come in Rome where this ebike is illegal i think is alot of fun too!!!!

    Monster motor

    Possible i have no chance to make this motor run at 125V and put out 30KW???? No controller on the planet right now can do this? Is so strange for me think this, please boys give me a solution!

    Monster motor

    i'm very tired, i think i solve problem with inductace, but yesterday i put a second pack of A123 7amp 125V of my friend in parallel, for have much power because with only one pack the battery sag very bad... And now controller cut-off again, maybe for less sag and more power input :( Seems if i...

    Monster motor

    No, i run my motor in forward, and KHB don't have noise reduction option, but i think all KHB make this noise, the controller KHB seems alot more noisy and conservative with power than old KBL, my kbl 136V 75-150A, easily overshot 200A from CA, my khb 200A, never go more than 150A CA... I think...

    Monster motor

    No video for now, but i want prepare soon, yes i use only CA, i hope don't loose sincro, but i want use gps too next ride :) In my experience 10kw out from 9C is heat, 10kw from a 65mm stator/magnet of a 22kg of motor is Torque! :) The same power can make totally different experience if come out...
