Title: INNER ROTOR BRUSHLESS MOTOR
Abstract:
[Problem] To increase motor efficiency and production characteristics. [Solution] In this inner rotor motor, which is provided with a rotor (20) that has a magnet and is supported rotatably and a stator (60) positioned at the periphery of the rotor (20) and affixed non-rotatably to the casing of the motor, the stator (60) results from a plurality of independent stator-configuring units (A) being provided in an annular manner, each stator-configuring unit (A) is equipped with a split core (61), which has a plurality of salient pole sections (61b) disposed at intervals in the peripheral direction and protruding inwards in the radial direction, and a coil (62a) wound around each of the plurality of salient pole sections (61b), and the plurality of coils (62a) in each stator-configuring unit (A) are configured in-phase.
