What is a Brushless Motor?
A brushless motor is a type of electric motor that operates without the mechanical brushes and commutator found in traditional brushed motors.
Instead, it uses an electronic controller to switch the current in the motor windings, which in turn rotates the motor’s rotor. This design significantly reduces friction, wear and tear, leading to enhanced durability and efficiency.
They are widely used in applications ranging from drones and electric vehicles to industrial machinery, where reliability and energy efficiency are paramount.
How Does a Brushless Motor Work?
A brushless motor operates through a combination of its main components: the rotor, stator, and an electronic controller.
- The stator generates a magnetic field using electricity, which is then controlled by the electronic controller to change its polarity.
- The rotor, equipped with permanent magnets, is pushed, and pulled by this magnetic field, causing it to spin.
- Unlike brushed motors, the electronic controller replaces mechanical brushes, enabling precise control over motor speed and position.
This setup minimizes friction and wear, leading to a more efficient, durable, and quieter operation.
How to Select the Best Brushless Motor?
Selecting the right brushless motor for your RC plane, quadcopter, or toys can be a challenging task. To make an informed decision, it’s crucial to understand the factors that should guide your purchase of these BLDC motors. Below are essential aspects to consider.
1. Motor Size
While purchasing a brushless motor, the first factor to consider the size. Manufacturers typically employ a standardized naming convention comprising a 4-digit number for motors. For example, consider a motor labeled as 2205. Here, the first two digits denote the stator diameter in millimeters, while the last two digits indicate its height, also in millimeters.
When evaluating these digits, it’s important to note that larger numbers signify the motor’s capacity to handle greater power output and consequently generate more torque. However, this tradeoff also results in a heavier or larger motor.
2. Speed
The motor’s speed is crucial for the performance of electronics or machinery. It is determined by the KV rating, which represents the number of revolutions per volt. This means the higher the voltage, the faster the motor spins. For example, a 2300 KV motor powered by a 4S LiPo battery (14.8V) will reach a speed of 34,040 RPM.
Below is a quick reference on how efficient the motor will run with chosen propeller.
- Motors with 2600 KV or higher are suited for 4-inch propellers.
- For 5-inch propellers, use motors with a KV rating between 2300 and 2600.
- Motors rated at 2300 KV or lower are ideal for 6-inch propellers.
3. Motor Shaft Dimensions
The diameter and length of the motor shaft are critical factors that should not be overlooked. A 5 mm shaft diameter is commonly preferred due to its compatibility with many propellers. If your motor has a smaller shaft, you can use a shaft size adapter to fit your props.
Conversely, for motors with larger shafts, you may need to enlarge the propeller’s hole. It’s essential to ensure that the shaft size can adequately accommodate the propeller and locknut, providing enough length (ideally 13 mm or more) to securely fasten the nuts and prevent thread stripping during operation.
4. Motor Power
Motor power is measured in Watts (W), calculated by multiplying Voltage by Amps. A higher wattage indicates a more powerful motor. When selecting a motor, it’s crucial to consider its amp draw to match it with an appropriate electronic speed controller (ESC).
Choosing an ESC with at least a 20% higher capacity than the motor’s maximum amp draw is recommended for efficient operation. For example, if a motor draws 20A, a 30A ESC would be suitable. This ensures the motor operates effectively without overloading the ESC.
5. Thrust Considerations
Understanding the thrust output of a motor, across different propeller and battery combinations, is essential for selecting the right motor size for your project. If you’re aiming for a model that weighs 2 lbs, for example, you should choose a motor capable of generating more than 2 lbs of thrust. This ensures your project has sufficient power for its intended use.
6. Weight Impact
For applications such as mini-quads, where multiple motors are used (typically four), every gram saved on the motor’s weight is crucial, as the weight savings are effectively multiplied across all motors. While heavier motors may offer more power, which can justify their additional weight, optimizing the balance between motor weight and power output is key to achieving efficient performance.
Brushless Motors – FAQs
Ans: Minor issues can often be fixed, but due to their complex internals, professional assessment is usually recommended.
Ans: Upgrading requires a compatible brushless motor, electronic speed controller (ESC), and sometimes a new battery, but it’s feasible with some technical know-how.
Ans: Sensored motors offer more precise control, ideal for applications needing smooth start-ups and accuracy. Sensorless are simpler and better for high-speed uses.
Ans: Efficiency varies, but brushless motors often operate at 85-90% efficiency, significantly higher than brushed motors.
Ans: Yes, but ensure the motor and ESC can handle the increased voltage to avoid damage.
Ans: Excessive heat can reduce efficiency and lifespan. Ensure adequate cooling, especially in high-power applications.
Ans: Inrunners have a stationary outer shell and rotate internally, suited for high-speed applications. Outrunners have a rotating outer shell, providing more torque.
Ans: With proper use and maintenance, brushless motors can last for thousands of hours of operation.
Ans: Yes, brushless motors can run in both directions by reversing the motor phase wires or through settings in the ESC.
