720 Coreless Drone Motor with Fan Blade - Micro Drone Replacement
720 Coreless Drone Motor with Fan Blade – High RPM Micro Motor
The 720 magnetic micro coreless drone motor is a compact, high-speed motor designed for micro drones and small unmanned aerial vehicles. It comes with an integrated fan blade that provides efficient thrust and active cooling during operation. With its lightweight coreless design and fast response, this motor is a reliable choice for custom drone builds, tiny whoop replacements, and hobby robotics.

Compatibility
This motor operates on 1S LiPo batteries (3.7 V nominal) and works seamlessly with common micro flight controllers such as BetaFPV, Crazybee, and Silverware boards. It can be driven by MOSFET-based motor drivers like the DRV8833 or directly by a transistor circuit when using a PWM signal from a microcontroller. Always ensure your power source can deliver at least 1 A per motor to avoid voltage dips.
Wiring Notes
The motor has two wires; polarity determines rotation direction. For drone use, connect each motor to a dedicated ESC or MOSFET driver output. When testing, start with a lower PWM duty cycle to avoid sudden current surges. If the fan blade is detachable, press-fit it gently onto the shaft until flush – excessive force may damage the coreless construction.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino-based drone projects?
Yes, this motor works well with Arduino and common motor drivers like L293D or L9110S when supplied with a 3.7V battery. Use PWM for speed control and a separate power rail to avoid brownouts on the Arduino.
Can the fan blade be replaced or removed?
The fan blade is press-fitted onto the 0.8 mm shaft and can be gently pulled off if needed. Replacement blades of similar hub size are available from our store; ensure a snug fit to prevent slipping at high RPM.
Will this motor survive a crash?
Coreless motors are relatively durable but can be damaged by direct impact to the can or shaft. With the fan blade acting as a shield, the risk is reduced. If a motor stops spinning after a crash, check for bent shaft or debris inside the housing.
