I want to build Ebike with 3KW 9kg rear hub motor / 72V 15AH C8 / 60A controller with CA to control Amps
EBIKE weight should be around 35KG and my weight is 60KG max
I want to know how the motor work and drains the battery in different situations, it's a little hard for me to put it so I'll just write it and hope you understand me(sorry for the broken language)
Is there a minimum power that the motor must work on? or just a maximum?
let's say 250W motor can handle 800W more then that and it will be destroyed right? in the same way an 3KW motor will not handle 7KW,it will be destroyed..true?
But what will happen in the opposite scenario? 3KW motor will get only 1200W (72V x15A) what will happen then?
it will adopt him too much or it will make him work without effort?
Right now i have E BIKE with 250W small motor / 48V 15AH and 15A controller,i drive around 42-45kmh for 40km(i believed i drive on 800W +-).
I want to know what happen with a 3 Kw motor / 72V 15AH and controller that i can function to different A through CA.
Now i want to use 3 different Amps for drive,and want to know what happen each situation:
With 10A DC - i will drive up to 45kmh for max 60km (800W)
With 25A DC - i will drive up to 60kmh for max 40km (1800W)
With 45A DC - i will drive up to 77kmh for max 25km (3400W)
Are these assumptions correct?
Or you say that everything I've put up until now is a mistake, and the motor must have minimal power and oblige me to use let's say 40A min and drive on 3000W and 70 KMH for 30KM and there's nothing I can do?!
Thanks to all the responders!
