Hi all!
Im planning on adapting an old motobecane 40v and turn it into something like this, aesthetically. i will keep the pedals.
The purpose of this is to have a cool summer/urban transportation and push it a little bit sometimes. :lol: something "fast" but most important than that, with good torque. So, after a lot of reading and simulating i came up with this set up, tell me your opinion!!
Motor:
MXUS V3 3000W 4T
Battery:
Samsung 25R cell 2500 mAh 3,6v (8C 20A max continuous discharge)
20s5p - 12.5Ah, max continuous current:100A
OR (and probably better)
Samsung 30Q cell 3000mAh 3,6v (5C 15A max continuous discharge)
20s5p - 15Ah, max continuous current:75A
Controller:
Xie Chang 80A 36-72V Sine Wave Controller 18 fet 4110 (Infineon clone)
36-72V
Maximal Voltage 90 V
80 A Battery, 200 A Phase
Wheel:
Im using 20" inch rims and tires, but outer diameter with tire its 23'' inch. Am i wrong assuming the 23'' as wheel size?
Total weight will be 120-130kg
After using motor simulator i got this:
I used motor phase 90A because from what i've read stock wires starts heating with 96A and above. Is this right?
Anyway, i felt "disapointed". Max power output is the nominal of the motor.
New simulation where i used 82V, 80A, 120A phase.
I think the second plot is more suited for what i want(obviously :b), where i can take more power out of the motor, from my calculations and plot information i will never reach the 80amp current draw but,
- Using 82 volts on that controller, because fully charged would go above the 90v maximal voltage
- Phase current of 120A on sotck phase wires. I know it requires some experiments to get the best phase current combination but for these phase current values should i change stock phase wires?
- Any tip for a more suitable controller(but with same features)? Tell me your thoughts! Thank you
