24V 5000RPM Outer Rotor BLDC Motor 0.05Nm Torque High Speed Dc Motor
24V 5000RPM Outer Rotor BLDC Motor JQ45BLW18-24V 0.05Nm Torque High Speed Dc Motor
The outer rotor construction also provides several performance improvements over the traditional BLDC motor design. The most noticeable of these benefits has to do with the rotor size. For the stator to reside inside the rotor, the rotor in a flat BLDC motor must be larger than that of a conventional BLDC motor. The larger rotor means a larger air gap, which provides a larger lever arm for torque production. This means that external rotor motors can produce more torque than their conventional, internal rotor counterparts. Combine this higher torque production with the overall smaller motor size, and the result is unrivaled power density.
