# Quick Answer: What does motor KV mean

Contents

Answer: “Kv” refers to the constant velocity of a motor (not to be confused with “kV,” the abbreviation for kilovolt). … The Kv rating of a brushless motor is the ratio of the motor’s unloaded rpm to the peak voltage on the wires connected to the coils.

## Does higher KV mean faster motor?

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 motor do I need?

As a guide, a good KV rating for a 1:10 scale brushless buggy or 400mm race/sport balanced speedboat motor is 3300KV – a smaller or more on-road/racing-focussed model will want a higher KV rating, whereas a larger or more off-road/sport-focussed model will want a lower one.

## How do I convert KV to RPM?

To estimate the RPM of a motor, simply multiply the Kv value by the battery voltage. Kv is in units of RPM/Volt. The more torque a motor needs to produce, the more current it will draw.

## 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.

## 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.

## What does 12 turn motor mean?

The 12 turn titan is a 550 motor so the armature is longer than the standard 540 motor(stinger) thus a 12 turn 550 has similar wire resistance as a 15 turn 540 motor as more wire is needed per turn around the armature. Sounds like your titan is dieing if the stinger is faster.

## How many turns is a 3300kV motor?

3300kV is closer to 13.5 in most situations, apples for apples.

## Which KV motor for drone?

For example, if the frame size is 150mm or smaller, then KV rating of 1306 or smaller size motor is prescribed with a propeller length of 3” or smaller (using 4S Li-Po Battery). For a 350mm frame size, 1600 KV motor and 7” propeller is advised. Lower KV motors are costlier than higher KV motors.

## What’s the best brushless RC motor?

## How is KV calculated?

It is measured by the number of revolutions per minute (rpm) that a motor turns when 1V (one volt) is applied with no load attached to that motor. The Kv rating of a brushless motor is the ratio of the motor’s unloaded rpm to the peak voltage on the wires connected to the coils.

## What is rpm V?

It is measured by the number of turns per minute (rpm) that an engine rotates when 1V (a volt) is applied without load connected to this engine. The Kv evaluation of a brushless engine is the ratio between the motors downloaded rpm and the peak voltage on the wires connected to the coils.

## What does KV mean in voltage?

A kilovolt (kV) is a decimal multiple of the SI derived unit for electromotive force, electric potential (voltage), and electric potential difference. 1 kV = 1000 V. By definition, one volt is the difference in electric potential across a wire when an electric current of one ampere dissipates one watt of power.

## What does turns mean on a RC motor?

Turns refers to the number of times the copper wire has actually been revolved around the armature. The higher the number of turns greater is the torque generated and hence greater is the power delivered. However that also means less RPM rating for your rc car electric motor.

## Why are there 3 wires on a brushless motor?

there are 3 wires because it’s a 3 phase brushless system. at any given time two provide power and the other is a sensor. So even though they may split their time doing each, at a split second in time two provide power and the third is a sensor.

## How many turns is a castle 4600kv?

A Venileon motor is rated at 3500kv which means it turns 3500rpm at 1v, a Castle Creations 4600kv motor turns at 4600rpm at 1v and so on an so forth.
