In the exhilarating world of micro-quadcopters and FPV racing, the difference between a sluggish, uncontrollable flight and a zippy, agile performance often comes down to one core component: the motor. For builders and pilots who demand speed, responsiveness, and a flawless power-to-weight ratio, the 720 Magnetic Micro Coreless Motor is the industry standard.
This isn't just a motor; it’s a meticulously designed power solution, packaged perfectly as a 2xCW & 2xCCW motor set, essential for achieving stable, high-performance flight. If you are serious about building, repairing, or upgrading your micro quadcopter, understanding the mechanics and configuration of this 720 coreless motor set is the first step toward dominating the skies.
A quadcopter’s motors must be light, quick to respond, and capable of high speeds—qualities that the coreless design embodies perfectly.
Unlike traditional brushed DC motors, which have a heavy iron core wrapped with copper windings, a coreless motor has its windings placed in a thin, light cup that spins around a fixed magnet. This design provides several critical advantages for micro-drones:
Extremely Low Weight: The absence of the heavy iron core drastically reduces the motor’s mass, which is critical for maximizing flight time and agility in small airframes.
Minimal Inertia: The light spinning cup allows the motor to accelerate and decelerate almost instantly. This rapid response is vital for the flight controller to make quick, precise adjustments, leading to the razor-sharp handling that FPV pilots love.
High Power Density: These motors achieve incredibly high RPMs (Revolutions Per Minute) for their size. The 720 coreless motor gets its name from its dimensions: 7mm diameter and 20mm length, the perfect size to power many popular micro-drone frames.
This unique blend of low inertia and high power makes the coreless motor the undisputed champion for micro drone motor applications.
The most misunderstood, yet critical, detail of any quadcopter build is the rotation direction. A helicopter uses a tail rotor to counteract the rotational force (torque) created by its main rotor. A quadcopter uses its four motors to cancel out this torque, and that’s why you must have a balanced set of clockwise (CW) and counter-clockwise (CCW) spinning motors.
The 2xCW & 2xCCW motor set ensures that your motors are paired correctly:
Lift Generation: Two diagonal motors (e.g., front-left and rear-right) will spin in one direction (CW), pushing air down and generating lift.
Torque Cancellation: The other two diagonal motors (front-right and rear-left) must spin in the opposite direction (CCW). As they spin, they generate an equal and opposite torque force, which perfectly stabilizes the entire airframe, preventing it from spinning uncontrollably.
Installing a CW CCW motor set correctly is non-negotiable for a stable flight. The motors are typically identified by their wire colors to prevent mixing them up during the build process (e.g., CW might be red/blue wires, and CCW might be black/white wires). Always consult your drone frame’s manual for the correct placement, but the principle of diagonal opposites remains the same.
Choosing a high-quality 720 motor set for quadcopter construction is the surest way to upgrade your flight experience. When paired with a reliable 1S LiPo battery, these motors provide:
Maximum Agility: The quick throttle response is essential for acrobatic maneuvers, fast turns, and rapid altitude changes. If your drone feels sluggish, these high speed coreless motors will transform its handling.
Balanced Thrust: A pre-matched set ensures that all four motors deliver consistent power output. Mismatched or generic motors can lead to a slight imbalance, forcing the flight controller to constantly overcompensate, which drains the battery faster and results in a less stable hover.
Reliable Lifespan: While coreless motors are brushed and will eventually wear out, a high-quality set like the 720 magnetic motor is built with durable components to ensure a long and consistent service life before replacement is necessary.
Installing this micro drone motor set is usually a simple press-fit into the motor mount. Always confirm the propeller direction matches the motor rotation before your first flight—an easy mistake to make! To maximize the lifespan of your motors, avoid long periods of high-throttle flying when the drone is grounded or stuck, as this can quickly cause the motors to overheat and burn out.
The 720 Magnetic Micro Coreless Motor (2xCW & 2xCCW) is the perfect blend of precision engineering and raw power. It provides the light weight, high speed, and directional reliability that is absolutely essential for stable and agile flight in any micro quadcopter. By choosing this dedicated, pre-matched set,
