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.

## What does the T mean on RC motors?

The “T” stands for turns. This is the number of times the wire inside the motor is wrapped around the stator. A smaller number of turns typically equals less resistance, and more power. A higher number typically means more resistance, and less power.

## What is T in brushless motor?

It is how motors are rated, and does not mean KiloVolts. … The lower the turns, the higher the R.P.M. of the motor. 3.5T means 10,500 RPM. 4.5T means 9,000 RPM. 5.5T means 7,400 RPM.

## What do motor numbers mean?

Generally, the first two numbers indicate the diameter of the entire can of the motor OR the diameter of the stator (the inner part of the motor) only. … Similarly, the second pair of numbers can indicate either the height of the entire motor, or only the height of the stator.

## What turn motor is faster?

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. Put simply, a 4.5T motor is faster than a 21.5T motor.

## What is the most powerful RC electric 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 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.

## How do I choose a brushless motor?

The physical size of a particular brushless motor is usually indicated by a number that looks like this – ’22-05′. The first number, 22, indicates how wide the motor is whilst the second number, 05, indicates the hight. Usually, these are written on the motor casing themselves to show you how wide and high they are.

## What kV is a 10.5 motor?

Novak’s 10.5s are 4,200KV.

## How do I read my brushless motor specs?

Brushless motors are typically categorized by a four-digit number – such as **##. where as the “**” numbers are the stator width and “##” is the stator height. Essentially, the wider and taller the motor is, the larger the numbers are and the more torque it can produce.

## How electric motors are rated?

Most electric motors are designed to run at 50% to 100% of rated load. Maximum efficiency is usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor’s efficiency tends to decrease dramatically below about 50% load.

## Does more turns mean more torque?

Increasing the number of turns will decrease the speed and increase the torque of the motor.

## 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.

## How do you make an electric motor spin faster?

The speed of rotation of the coil can be increased by:

- increasing the size of the current;
- using a stronger magnet;
- increasing the number of turns of wire in the coil;
- reducing friction between the coil and the axel it rotates on.
