Fast response, High power density

Inner rotor brushless motor's coil is outside and has inner permanent magnet rotates. It has low moment of inertia and is suitable for situations requiring fast response and high torque moment of inertia ratio, especially for servo applications. Benefit from the outer stator core , it has excellent heat dissipation conditions and is easy to install. The inner rotor motor is more suitable for the occasion of indirect drive by the deceleration mechanism, the motor can be designed with higher speed and higher power density.
