# Your question: What is kV rating of motor?

## What does RC motor KV mean?

The Kv rating (not to be confused with kilo-volt) is the RPM of the motor (k) per volt (V) with no load. … A motor with a higher Kv will have more top end speed, but not as much acceleration/torque. A motor with a lower Kv will not be as fast, but will accelerate faster and have more torque.

## What Kv is a 13.5 motor?

Like I said prior, my 13.5t is between about 3000-4000 kv, but thats just a general range.

## Is KV the same as RPM?

The higher the voltage, the faster a motor spins. The Kv rating designates the RPM a motor will spin at full throttle when unloaded given an input voltage. To estimate the RPM of a motor, simply multiply the Kv value by the battery voltage. Kv is in units of RPM/Volt.

## Is higher or lower KV better?

Generally speaking the more Kv a motor has, the more RPM and more power. For example, a 9000Kv motor would be faster than a 2200Kv motor. … 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.

## What Kv is a 10.5 motor?

Novak’s 10.5s are 4,200KV.

## Does lower KV mean more torque?

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.

## What does 2300kv mean?

KV Means RPM/Volt. … 2300kv represents the rpm of the motor per volt applied to the motor. The motor will spin at 2300 rpm with 1 volt applied. If you apply 10 volts, your motor will spin 23,000 rpm.

## 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 is the difference between a sensored and sensorless motor?

All brushless motors used in RC applications have three main wires, but sensored motors have an addition multi-wire loom that connects the “brains” of the speed control to the motor. … Sensorless motors simply do not have sensors inside the motor—hence the name sensorless.
