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 size engine does my RC plane have?

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 do I choose an electric motor for my RC plane?

The maximum current and power is what determines how large of a prop and what size plane can be used with the motor. Simply multiply the current by the battery voltage to get power. The larger the propeller’s diameter and pitch, the more current the RC electric motor will draw for a given RPM.

## What is the most powerful electric motor for a car?

In other EV news, British company Equipmake has developed what it claims is the “world’s most power-dense permanent magnet electric motor.” The company’s Ampere motor weighs just 22 pounds but develops close to 300 hp.

## What does KV mean on a motor?

kilovolt

## Which motor is used in RC plane?

There are two main different motor types used in model aircraft: The brushed and the brushless. containing a stator and a rotor.

## How do I choose a brushless motor?

How To Select the Best Brushless Motor?

- Motor Size: One should determine the size of the motor before they are going to purchase or use it. …
- Speed & RPM Constant: …
- Winding Size: …
- Arc Magnets: …
- Motor Shaft: …
- Power: …
- Thrust: …
- Electronic Speed Controller (ESC):

## What do the numbers mean on RC electric motors?

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 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.

## How are RC electric motors rated?

kV Ratings

The letters kV stand for the the RPM of your motor per volt with no load. For example if you own a brushless motor with a kV rating of 4600 and 12V. Take the 4600, multiply by 12 to get 55,200 RPMs. This is the max RPMs that this motor can reach under no load.

## How big of an electric motor is needed to power a car?

The common “in the field” estimate of KW power a 9″ motor can handle (for short periods) is 100 KW. So using the above formulas, 144 volt system should be limited to about 700 amps, and the 288 volt system to 350 amps. Still, 135 hp is pretty good for a small car.

## Can I put an electric motor in my car?

Basically, electric conversion involves removing the entire internal combustion engine from a vehicle, installing an electric motor in its place, and also adding a large bank of batteries. … You can expect your converted vehicle to have a range of 60-80 miles, a top speed of 50-90 MPH, and good acceleration capabilities.13 мая 2020 г.

## How long does an electric motor last?

15 to 20 years

## How do I know what RPM My brushless motor is?

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.

## Does higher KV mean faster motor?

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. … A higher turn number means more wire and thus more resistance, resulting in a slower motor.

## 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.
