I m not sure that, but some ching in jv said if the magnet is thinner, the motor彈岀去when u exit ...
我會這樣理解,
Larger rotor diameter -> smaller distance between the rotor and coils -> higher magnetic flux density -> higher torque -> rotor is tightly controlled
Small rotor diameter -> larger distance between the rotor and coils -> smaller magnetic flux density -> smaller torque -> rotor can easily spin off control, rotate freely due to insertia, this effect would be beneficial while driving our cars entering corners. I didn't experience the differences between those two but the idea sounds nice to me. Thank you!
Use a MOD motor, always say NO WAY to the turbo, unless somebody who doesn't care about overheating.
