# Your question: How do you find the wattage of a brushless motor?

Contents

Watts are the power rating or the horsepower equivalent of your Brushless RC Motor. (It takes 746 Watts to equal one Horse Power by the way, just a quick bit of info). Watts equals Amps multiplied by your battery voltage or (Amps x Volts).

## How do I know the wattage of my brushless motor?

Identify the maximum power (BHP) of the motor. Divide this by 1.5 i.e. 2/3s and multiply by 750 to convert the BHP to watts to determine the output power of the equivalent brushless electric motor.

## How is brushless motor power measured?

Watts are the power rating or the horsepower equivalent of your brushless RC Motor. The math here is Amps x Volts = Watts. You will see a watt rating in the brushless motor specs. Your brushless motor should have a watt rating on its spec sheet, something like “180W”.

## How is motor wattage calculated?

Calculate the power the motor consumes while in operation. The equation is W = AV(sqrt 3) where A is amperes, V is volts, and sqrt 3 is the square root of 33 (about 1.73). W is the power consumption in watts. For example, if the electric motor uses 50 amps at 240 volts, the wattage is 50 x 240 x 1.73, or 20,760 watts.

## What is the Kv rating on a brushless 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. 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 fast can a brushless motor go?

These motors provide a great amount of power to RC racers and, if paired with appropriate gearing and high-discharge lithium polymer (Li-Po) or lithium iron phosphate (LiFePO4) batteries, these cars can achieve speeds over 160 kilometres per hour (99 mph).

## How do you determine the rpm of a brushless motor?

Motor RPM Calculation Examples

1. (Hz x 60 x 2) / number of poles = no-load RPM.
2. (60 x 60 x 2) / 4.
3. 7,200 / 4 = 1,800 RPM.

## What do the numbers mean on a brushless motor?

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 do I choose a brushless motor?

## What is wattage formula?

The formula for calculating wattage is: W (joules per second) = V (joules per coulomb) x A (coulombs per second) where W is watts, V is volts, and A is amperes of current. In practical terms, wattage is the power produced or used per second. For example, a 60-watt light bulb uses 60 joules per second.

## How many watts is a 1 hp motor?

One electric horsepower is equal to exactly 746 watts.

## How do you calculate watts per hour?

A kilowatt-hour, expressed as kWh or kW·h, is a measure of energy that is equivalent to 1,000 watts of power for a 1-hour time period. Thus, to convert watts to kilowatt-hours, multiply the power in watts by the number of hours, then divide by 1,000. For example: let’s find the kWh of 1,500 watts for 2.5 hours.

## Is a higher Kv motor better?

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 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 does 12 turn motor mean?

A 12 turn motor will be tons faster and will drain a battery faster . Just as he said. a twelve turn motor will have more RPM, less torque, and draw more current. The number or turns refers toi the number of times the wire is warpped around your armature in the motor.
