What do the numbers on RC motors 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. … Typical FPV racing miniquads will use 1806 or 2204 motors, whereas larger quadcopters that are designed to carry a gopro camera will typically be around the 2212 size.

What does the number of turns on an RC Motor mean?

The number of turns indicates how much wire is wrapped inside the motor. A higher turn number means more wire and thus more resistance, resulting in a slower motor.

What do the numbers mean on brushless motors?

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. KV is another essential parameter.

What is KV rating on RC Motors?

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. Knowing the Kv rating of a motor will help you determine how fast that motor will rotate when a given voltage is applied to it.

How do I know what size my RC motor is?

Electric motor power is stated in watts. 750 watts = 1 horsepower. An easy way to estimate power needs for RC hobby applications is to use 100 watts per pound for sport flying, 150 for aggressive aerobatics, 200 watts per pound for 3D flying.

How long do Brushless RC Motors last?

If you are looking for a motor with a long life expectancy, consider a brushless motor. Brushed motor life is limited by the brush type and can attain 1,000 to 3,000 hours on average, while brushless motors can attain tens of thousands of hours on average, as there are no brushes to wear.

How do you break in a brushless RC motor?

Without brushes, there isn’t anything to break-in. Just set it up per the manufacturers instructions, and use it. It’s part of the beauty of brushless! Without brushes, there isn’t anything to break-in.

What is the fastest brushless RC motor?

Traxxas XO-1

How many turns is a 3300kV motor?

13.5

How do you determine the rpm of a brushless motor?

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. The Kt rating designates the amount of torque a motor will produce given a current.

How do I choose an RC motor?

Inrunners tend to be bigger for lower RPMs than outrunners. You can guess that the first thing you need to decide then is what speed (RPM) you want your motors to run at. You can get the RPM from the theoretical max speed you want your RC vehicle (theoretical max thrust if it flies).

What is a 12 turn RC motor?

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.

Why does a brushless motor have 3 wires?

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.

Which electric motor is equal to what glow engine?

25 size engine equals about 500 watts, a . 60 size engine equals around 1200 watts and a . 90 size engine equals about 1800 watts of electrical power. When considering a 4-stroke glow engine, the conversion factor is around 1500 watts per cubic inch.

What is a 540 size motor?

540 has a diameter of 36mm. 380 has a diameter ~28mm. 280 has a diameter of 24mm. The S, L or XL after the numbers refers to the motor length.
