Claims

[Scope of utility model registration request]

In a brushless motor with an in-hub structure in which a core is disposed inside the rotor, a sensor board is attached to the rotor side on one side of the stator of the motor, and a circuit connection board is attached to the other side of the stator. A brushless motor characterized in that the sensor part board and the circuit part connection board are connected by a through-hole pin passing through the stator in order to maintain airtightness between the sensor part board and the circuit part connection board.
