Is higher or lower KV better?
The kV rating is the RPM of the motor with no load, not the kilo-volt. A motor that has a higher kV will have more top end speed, but not as much Torque. A motor with a lower kV will have more power and will accelerate faster.
What is the fastest KV motor?
The 4000 Kv motor is faster – at the same voltage. The 4000 Kv in the BLS models are rated for 2s (7.4v) while the 3600 Kv motor in the BLX is rated for 3s (11.1v). The higher the RPM the faster top speed.
Is higher KV better for RC car?
Looking at the result makes it apparent that higher kv motor does increase the axle speed of our RC car. Higher axle speeds do increase the overall RC car speed. The simplistic answer is yes, higher kv does increase the speed of your RC car.
Is higher KV more efficient?
Generally speaking the more Kv a motor has, the more RPM and more power. … A higher turn number means more wire and thus more resistance, resulting in a slower motor. So turns with a lower number means a faster motor. The turn rating is inversely proportional to the power generated by the motor.
How many turns is a 3800kv motor?
If you are going to race the 13.5T class than you will need to buy a 13.5T motor. The Castle 3800 is about a 10.5T 11T in terms on power to turn for the motor.
Does lower KV mean more torque?
Kv allows you to get a handle on the torque that can be expected from a particular motor. Torque is determined by the number of winds on the armature and the strength of the magnets. A low Kv motor has more winds of thinner wire—it will carry more volts at fewer amps, produce higher torque, and swing a bigger prop.
How many KV is a 8.5 turn motor?
A 5000 KV motor is a 5000 KV motor. A Novak 8.5 “turn” is rated at 5000 KV but another manufactures 8.5 may be different as most do not post their KV rating.
What is a 540 size motor?
Those numbers refer to the motor diameter. 540 has a diameter of 36mm. 380 has a diameter ~28mm. 280 has a diameter of 24mm.
What’s the fastest brushed RC motor?
“The Traxxas XO-1 is the fastest RC car, full stop. The largest brushless motor on offer propels the car from 1 to 60 in 2.5 seconds. Not only is this car stylish, but it also reaches speeds over 100 miles per hour.”
What does 12T mean on RC motors?
Twelve turns around each motor pole using triple wires. Three wires are would twelve times around the pole. A 12T double would use two wires wound twelve times and a 12T single a single thicker wire wound twelve times around each rotor pole.
