Description

The 720 Magnetic Micro Coreless Motor provides a straightforward propulsion solution for micro-class drones and experimental multirotor platforms. Operating at a nominal 3.7V, it delivers high rotational speeds suitable for lightweight airframes where minimal torque requirements are acceptable.

This set pairs each motor with a robust 55mm propeller, engineered from durable plastic to withstand minor impacts during flight testing and indoor use. The combination offers a balanced performance profile for pilots seeking to understand coreless motor characteristics and basic drone aerodynamics.

Key Features

  • Magnetic coreless design for smooth, low-vibration operation.
  • Metal motor casing enhances durability and heat dissipation.
  • Pre-soldered 5cm wire leads simplify integration into micro drone frames.
  • Propellers feature a standard hub design compatible with 720, 8520, and 615 coreless motor shafts.
  • Optimized performance-to-weight ratio for micro quadcopter applications.

Applications

  • Ultra-micro DIY quadcopter and hexacopter prototypes.
  • Lightweight indoor drone platforms and educational STEM kits.
  • Small-scale multirotor designs requiring sub-8mm motor diameters.
  • Replacement propulsion for toy-grade drones using 720-series coreless motors.

Frequently Asked Questions

What is the main difference between a coreless motor like the 720 and a standard brushless motor?

Coreless motors, such as the 720, lack an iron core in the rotor, resulting in lower inertia, faster response, and less electrical noise. However, they provide significantly lower torque compared to brushless motors of similar size, making them suitable only for ultra-lightweight micro drones where high RPM is prioritized over thrust.

What type of battery is required to power these 720 coreless motors?

These motors are rated for a nominal 3.7V, which corresponds to a 1S LiPo battery. It is crucial not to exceed this voltage, as higher input (e.g., 2S 7.4V) will quickly overheat and damage the motor due to its low current draw (0.1A) and minimal thermal mass.

Are the included 55mm propellers a direct fit, or do they require an adapter?

The propellers are designed with a hub that fits the 1.0mm shaft diameter of the 720 motor. They should press-fit directly onto the shaft without requiring an additional adapter. They are also compatible with other coreless motors in the same size family, such as the 8520 and 615.
