The wise one answers:
Yessh a good question that is! Both are measurements of potency. A brushed motor is measured in turns. The lower the turns then the faster it will spin for a given input voltage. Also the lower the torque though so normally some gearing down is needed.
Brushless motors are rated in kv. This is the RPM for an input voltage. A brushless motor of 1100kv on an 11.1v Lipo battery would spin at 1100 x 11.1 = 12,210 rpm. You can see that the higher the kv rating, the faster the motor would be. |
