れることを特徴とするブラシレスモータ。[Claims for Utility Model Registration] A stator board disposed on a bearing member and having a circuit pattern; a plurality of flat driving air-core coils disposed annularly on the stator board; and a shaft rotatably mounted on the bearing member. a supported rotor yoke, a rotating field magnet fixed to the rotor yoke so as to face the driving air-core coil, and a bare chip-shaped position detector placed on the stator board to detect the position of the magnet. element, and in a state where the air core coils are arranged in a ring, each air core coil has a size that makes it impossible to arrange the position detection element on the stator substrate facing the magnet around the air core coil. The position detection element is connected by wire bonding to a circuit pattern located in the hollow part of the air-core coil,
The brushless motor is further characterized in that the hollow portion is sealed with a filler.
