Demystifying Poles and Magnets in FPV Motors
As you delve into the world of FPV drones, you may encounter terms like "12N14P" or discussions about poles and magnets. Understanding these concepts is essential for making informed decisions when selecting motors for your FPV build. In this article, we'll dive into the details of poles and magnets, their significance, and how they affect motor performance.
Poles and magnets are fundamental components of an FPV motor. The number of poles refers to the electrodes within the stator, while the number of magnets pertains to the permanent magnets attached to the bell.
When it comes to pole configuration, different motor sizes exhibit varying numbers of poles. For example, 22XX and 23XX motors commonly feature 12 poles and 14 magnets. The pole count plays a crucial role in determining motor performance and characteristics.
Let's explore the impact of poles on motor performance:
1. Smoother Performance with More Poles:
Motors with a higher number of poles generally deliver smoother performance. This is because an increased number of poles results in a more evenly distributed magnetic field. The smooth-running motor exhibits finer control over the rotation of the bell, allowing for precise and fluid movements during flight. This level of control is particularly desirable in aerial cinematography or other applications where smooth operation is essential.
2. Increased Power with Fewer Poles:
On the other hand, motors with fewer poles tend to offer increased power output. With fewer poles, there is more room for additional iron content in the stator, leading to enhanced power generation. These motors excel in scenarios where raw power is required, such as racing or freestyle flying. They provide a burst of acceleration and high-speed performance, ideal for those adrenaline-fueled FPV flights.
It's important to note that the pole configuration must be a multiple of 3 for FPV drone motors since they typically operate on a 3-phase system. The presence of three wires connecting to the motor necessitates this configuration. As a result, the pole count is not easily modified and is not a critical factor when selecting motors, especially for FPV drones.
However, it's worth paying attention to the pole count when configuring your flight controller. For instance, when enabling the RPM filter in Betaflight, you'll need to enter the correct pole count. If the pole count is not readily available, a simple count of the magnets on the bell will suffice.
In summary, understanding poles and magnets is crucial for comprehending motor specifications and their impact on performance. More poles result in smoother operation, while fewer poles offer increased power output. By considering these factors alongside your intended flying style and application, you can choose motors that align with your specific needs and achieve optimal performance in your FPV drone.
