550 vs 540 -
03.12.2010, 12:19 PM
Since the HV 550 motor has a stator and rotor magnet that are almost twice the length of a 540 motor, it will have twice the torque of an equivalent Kv 540 motor.
HV 4.5 550 (5000Kv)
Bal. 8.5 540 (5000Kv)
Therefore, if you are running two motors (one 540, one 550) with equivalent Kv in the same vehicle under equal driving conditions, the 550 motor will only have to work about half as hard and will heat up about half as much as the smaller motor.
