Kv describes the RPM (revolutions per minute) a motor does per Volt that is put into it. 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. If Kv is like horsepower, then Turns is the physical attribute of a motor.

## How do you calculate Kv on a motor?

The formula to calculate Kv for a brushed DC motor is to just divide the speed by the generated DC voltage that you measure using your multimeter. Another option for brushless motors is to buy a BL motor tester that will calculate Kv for you.

## 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.

## How do you calculate Kv?

Flow Calculation – (Kv)

- Kv = m3/h – Flow coefficient.
- Q = m3/h – Flow.
- Qn = m3n/h – Normal flow (20°C 760mm Hg)
- P1 = bar – Inlet pressure – (Gauge pressure + 1)
- P2 = bar – Outlet pressure – (Gauge pressure – 1)
- DP = bar – Pressure drop – (Differential pressure between inlet and outlet pressure)

## What is a high Kv motor?

Answer: “Kv” refers to the constant velocity of a motor (not to be confused with “kV,” the abbreviation for kilovolt). … A high Kv motor has fewer winds of thicker wire that carry more amps at fewer volts and spin a smaller prop at high revolutions.

## What does 1000Kv Motor mean?

Suppose if you are having a motor with 1000Kv rating it means that it will produce 1000 RPM when 1 volt is supplied. Suppose you are using a 3 cell battery which gives 12.6V.

## What is kilovolt mean?

Definition of kilovolt

: a unit of potential difference equal to 1000 volts.

## What is name of KV?

## Which is bigger volts or kilovolt?

One kilovolt is equal to 1,000 volts, which are the potential difference that would move one ampere of current against one ohm of resistance. The kilovolt is a multiple of the volt, which is the SI derived unit for voltage.

## What is KV rating on RC Motors?

The Kv rating (not to be confused with kilo-volt) is the RPM of the motor (k) per volt (V) with no load. For example, a brushless motor with a Kv rating of 3000 powered by a 12V power source would be capable of 36,000 RPMs (multiply 3000×12). This is the max RPMs that this motor can reach under no load.

## What is the fastest brushless 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 Kv is faster?

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. If Kv is like horsepower, then Turns is the physical attribute of a motor.

## 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.

## How many turns is a 3300kv motor?

3300 is 13.5 equiv if it were a Novak motor.
