An inner rotor type brushless motor includes a stator. The stator is made of a plurality of stator sections. Each one of the stator sections has a plurality of core members, an insulator, and a winding wound on the core members via the insulator. The core member includes a yoke portion and a tooth portion. The insulator includes a ring portion to connect the core members. Since each stator section can provide sufficient distance and space between two core members on the same stator section, it is easy to wind the winding on the tooth portions. The stator sections can be assembled along an axial direction to form the stator. The yoke portions are circumferentially arranged to connect each other to form a magnetic path.
