More eff if uadjust top speed w gearing to what it was at 10s. But assuming u dowqnt that top speed, if u gear it more for lower top speed even more eff
i just calc’d it, i need about 32 teeth wheel pulley and about 15 -16 teeth motor pulley… this sounds to me like a big torque loss if i only could add up 2S more for more rpm at higher speeds
a motor running with 10S instead of 12S has roughly 80% as much peak mechanical power and rpm with the same motor amp (torque) limit… so onto my question…
at 10s how can he reach the same top speed with a motor delivering only ~80% as much peak mechanical power and rpm but the same amount of copper loss and torque?
gearing can increase torque at the proportional expense of rpm, or increase rpm at the proportional expense of torque. mechanical power is torque in newton meters * angular speed in radians per second. changing the gearing doesn’t change the peak mechanical power output of the motor, unlike changing the voltage or motor amp limit.
Yea. Les power so less speed.
12s bro no bs. don’t understand why this is even a discussion!
ride a 10s set up and ride a 12s setup…
10s is for ladies who cant handle the power
