There are something wrong with your table :atkforever said:My motor is a MXUS 3K rated at 3000W nominal (90N.M torque and 800RPM at 60V)
speed = radius times angular velocity (speed in m/s radius in meter and angular velocity in rad/s)
With your values : 26 inch wheel : speed = 27.4 m/s = 98 km/h !!!
Mechanical power = torque times angular velocity (power in W, torque in N.m and angular velocity in rad/s)
With your values :
Mechanical power = 90 x 800 x 2 x pi /60 = 7500W !!!!
3000W is the electrical power of the motor (if it's correct)
The battery provides 3000/60 = 50 amps for the rated power. it sounds a lot.
In my opinion, I would start with 20 amps. You risk nothing and if everything works well, I would increase gradually.
