How to Match an RC Brushless Motor and a Brushless ESC

One of the most enjoyable aspects of hobby-grade radio-controlled (RC) vehicles is that they offer a superior level of customization. With the countless varieties and options available, it is important that you are well-informed before you make a final purchase. Learn how to properly match a brushless motor to a brushless electronic speed control (ESC), to ensure your system is functional, and capable of achieving your ideal level of performance.

Things You'll Need

Brushless motor
Brushless electronic speed control (ESC)

Instructions

- 1
  Choose the brushless motor that best suits your power requirements. Motors are rated by their windings, which are directly related to the torque and maximum rotations-per-minute (RPM). Decide if you prefer great acceleration and high torque, or exceptionally high top speed. Choose a high-turn motor for acceleration (i.e. 14T) and a low-turn motor for high speed (i.e. 6T)
- 2
  Identify the peak current drawn by your motor, this is usually listed on the packaging; however, if it is not, take note of the number of turns, since this is an important figure when considering an Electronic Speed Control (ESC) purchase.
- 3
  Choose an ESC that has an rating that matches or exceeds the peak current draw of the motor. Decide if you require a reverse option, since not all ESC's offer that function. Make sure to match the max rating to the maximum current draw of the motor because this is the only aspect that could result in damaged electronics.
