Drones, given their widespread applications, necessitate a variety of motor cores to cater to different requirements. Here are the primary types of drone motor cores based on functionality and design:

Brushed Motor Core

These are the traditional DC motors that use brushes to rotate the shaft. They are simple in design and relatively inexpensive but wear out faster because of the friction from brushes. They are commonly found in beginner and toy drones due to their lower cost. However, they might require more maintenance due to brush wear and tear over time.

Brushless Motor Core

As the name suggests, Brushless motors don’t use brushes. Instead, they employ a controller to rotate the shaft. They are more efficient, have a longer lifespan, and produce less heat than brushed motors. They are predominantly used in professional, racing, and high-end drones because of their efficiency and durability.

Permanent Magnet Motor Core

Permanent Magnet Motors utilize permanent magnets to generate magnetic fields. Cores offer excellent efficiency, torque, and speed over various applications. Their superior efficiency ensures lower energy consumption and extended drone flight times. Especially relevant in today’s energy-conscious world, Permanent Magnet Motor cores are gaining traction in high-performance drone applications.

Drone motor Cores FAQs

Brushless motors, commonly used in drones, don’t use brushes for communication, which reduces friction and wear. This results in higher efficiency, longer lifespan, and less maintenance. In contrast, brushed motors use brushes, making them simpler but less efficient and durable.

Drones, especially the multirotor variety commonly used for photography, surveillance, and recreational purposes, employ specific motors to achieve flight. Here are the primary types of motors used in drones:

Brushless DC Motors (BLDC):

Advantages: These are the most common types of motors used in modern drones. They are more efficient than brushed motors because there’s no physical contact between different parts, resulting in less friction, less heating, and a longer lifespan. They also offer better performance, reliability, and lifespan. BLDC motors are quieter and require less maintenance than brushed motors.

Disadvantages: They are generally more expensive and require electronic speed controllers (ESC) to operate, which can add to the overall cost.

Brushed DC Motors:

Advantages: These motors are simpler and typically cheaper than brushless motors. They were used in earlier drone models and are still in some toy drones.

Disadvantages: Brushed motors have brushes that wear out over time, resulting in a shorter lifespan. They can also be less efficient than brushless motors and produce more noise.

Stepper Motors:

Usage: These are not typically used for drone propulsion but can be found in some specialized applications like camera gimbals for precision control.

Advantages: They offer precise control because they move in discrete steps.

Disadvantages: They are generally less efficient than BLDC motors and can be bulkier.

Coreless Motors:

Usage: These are used in very small drones or nano drones.

Advantages: They are lightweight and provide a quick response, making them suitable for tiny drones.

Disadvantages: They tend to have a shorter lifespan compared to BLDC motors.

Permanent magnet motors employ permanent magnets to produce the required magnetic fields. This design minimizes energy loss, offers excellent torque, and provides consistent power. Their superior efficiency ensures drones consume less energy, leading to extended flight times.

Yes, you can use AC motors for drones, particularly the AC brushless motors, also known as Permanent Magnet Synchronous Motors (PMSM). Drones commonly utilize brushless motors, and there are two main types: DC brushless motors (BLDC) and AC brushless motors (BLAC or PMSM).

Both types offer efficiency, longevity, and maintenance advantages over traditional brushed motors. While BLDC motors use trapezoidal waveforms and are more common in hobbyist drones due to their simplicity and ease of control, BLAC or PMSM motors use sinusoidal waveforms and can offer smoother operation.
