How do I choose an RC motor?

What motor should I use for RC car?

What’s perhaps still the most common motor size used in RC cars, is often called “540”. These are used in many lighter 1/10 cars, while larger “550” or “1/8” sized motors are often used in heavier 1/10 vehicles and 1/8 scale cars. Brushless motors in this size are today often “4-pole” motors.

How do I choose the right motor?

Consider an application’s purpose and which current it uses to select the appropriate type of motor. An application’s specifications such as voltage, current, torque, and velocity will determine which motor is most appropriate so be sure to pay attention to its requirements.

What turn motor is best for RC drifting?

RC motors are measured in turns, which is the amount of winds in the electric motor’s coil, and the lower the number, the more powerful it is. A 9T motor for example, has a lot more power than a 17T motor. For drifting you ideally want a sensored brushless motor for the best throttle control, but other setups do exist.

Are RC motors the same size?

Upgrading from a brushed to a brushless system is one of the easiest and most effective upgrades that you can make to your electric vehicle. Much like the scale of RC vehicles varies, motors vary in size as well.

How do I choose a BLDC motor for my RC plane?

This is Voltage x Amps. The higher the number, the more powerful it will be. You’ll also need to make sure to specifically check how many Amps that a motor pulls in order to find the right Electronic Speed Controller (ESC). Use an ESC that is at least 20% larger than this number.

How many amps does an RC motor draw?

Around 60-80 amps.

How do I match battery with ESC?

Your ESC should match the battery voltage, for example, a 3-cell battery with 11.1V can be paired with a 12V ESC. The Amp rating is the most important factor to remember here. Your ESC should have a threshold amp rating of about 10% more than the burst rating of the motor.

What size ESC should I use?

The ESC can be selected based on the voltage and the peak current rating of the motor. A simple rule is to choose an ESC with atleast 5A more capacity than the peak rating of the motor, since you may be powering servos, receiver and other accessories from the ESC. Remember to always round up.

How do I know what size electric motor I need?

Divide the motor speed by the required speed and round down to get a starting gear ratio. Then divide the required torque by the gear ratio to find the newly required torque. This will help you narrow the choices down to a few select motors.
