rotor size

[sly]

big rotors equal ?
small rotors equal ?

[jim76]

big rotor -14mm = torque
small rotor - 12.3mm = RPM

Yup - size not necessarily true for all motors but you get the idea.

Cheers guys

Small rotor also equals less brakes, more heat and higher power consumption...

The smaller the gap between the rotor and the stator, the more efficient the motor is.

If possible, using a slightly lower than normal turn motor with the large rotor will give best results.
