Basics to Brushless RC Vehicle Electric Motors

Introduction:

The advent of brushless motors has revolutionized the world of radio-controlled (RC) vehicles, offering hobbyists and enthusiasts unparalleled performance and efficiency. In this article, we will delve into the realm of brushless RC vehicle electric motors, exploring their power requirements, KV ratings, motor sizes, and how to choose the right one for your needs.

 

Power Requirements:

To determine the ideal brushless motor for your RC vehicle, you must consider several factors such as weight, type of terrain, battery capacity, and desired speed. A general rule is to choose a motor with sufficient power to support twice the average load for optimal performance.

 

KV Ratings: 

KV (RPMs per volt) is a standard measurement used in brushless motors that determines the rotational speed of the motor at a given voltage and load. A higher KV rating corresponds to faster motor speeds, while a lower KV rating indicates slower speeds. The choice between high-KV and low-KV motors depends on the intended use: high-KV motors are suitable for lightweight vehicles used on smooth surfaces, while low-KV motors are better suited for heavier vehicles used on rough terrains.

 

Motor Sizes:

Brushless motor sizes are determined by a series of numbers and letters representing the diameter (first number), length (second number), and maximum current rating (letters). For example, a 2206 motor refers to a diameter of 22mm, a length of 6mm, and a maximum current rating of approximately 35-40A. Choosing the right motor size is essential for achieving the desired performance, torque, and speed.
