Mfano na gari isiyo na brashi ina thamani ya mia hadi 23000 kV ni ya chini, juu hadi 56000, kila ongezeko 1 V, inawakilisha voltage, thamani ya kuongezeka kwa kasi. Kwa gari isiyo na brashi, thamani hii ni ya mara kwa mara.
Thamani ya KV ya Motors: Kasi ya gari (hakuna-mzigo) x = kV thamani ya voltage; Kwa mfano KV1000 IT chini ya voltage 10 ya V ya kasi ya gari, hakuna mzigo) ni 10000 rpm.
Kwa saizi sawa ya brushless:
idadi ya vilima ya gari, thamani ya chini ya KV, pato la juu la sasa ni ndogo, lakini torque kubwa;
Idadi ndogo ya zamu ya vilima vya motor, thamani ya juu ya KV, upeo wa sasa ni mkubwa, lakini torque ndogo;
single from KV value, not can evaluate the quality of the motor with KV high and low, also can not to measure motor pulling force is strong with KV, because different KV value have different applicable occasion:
* low voltage (7. 4v）
KV value is low, because of the low speed, match with small reduction ratio and large propeller, ascension by large load current, the output is high power;
high KV value, due to the high speed, match with large reduction ratio and the Kidogo cha propeller, chini ya hali ya kukutana na nguvu, kupunguza mzigo, na
