## How do you size 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 do the numbers on brushless motors mean?

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.

How do you calculate the power of a brushless motor?

motor you would use in the model. 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 do I know what size brushless motor I need?

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.

### What does KV mean RC motor?

What is the Kv rating of an electric motor? Answer: “Kv” refers to the constant velocity of a motor (not to be confused with “kV,” the abbreviation for kilovolt). 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.

How do you determine the maximum RPM of a brushless motor?

The higher the voltage, the faster a motor spins. The Kv rating designates the RPM a motor will spin at full throttle when unloaded given an input voltage. To estimate the RPM of a motor, simply multiply the Kv value by the battery voltage.
