Brushless motor

A brushless motor comprising:

• a shaft;
• a rotor magnet coupled to the shaft;
• stator coils of a plurality of phases arranged so as to surround the rotor magnet about an axis and rotating the rotor magnet;
• a coil cover formed in a cylindrical shape housing the rotor magnet therein and holding the stator coils of the plurality of phases on an outer peripheral side;
• a circuit board disposed on one end side of the coil cover and configured to detect rotation of the rotor magnet by Hall elements of a plurality of phases mounted and arranged about the axis;
• and
• a coil cap disposed between a board-side cover edge of the coil cover and the circuit board and holding the circuit board,
• wherein the cover edge is formed with a coil-side positioner for positioning the coil cap about the axis with respect to the stator coils of the plurality of phases,
• the coil cap is formed with a cap-side first positioner in which the coil-side positioner is to be fitted,
• the coil cap is formed with a cap-side second positioner for positioning the Hall elements of the plurality of phases about the axis with respect to the coil cap,
• the circuit board is formed with a board-side positioner in which the cap-side second positioner is to be fitted, and
• a relative positional relationship about the axis between the cap-side first positioner and the cap-side second positioner is such a positional relationship that the Hall elements of the plurality of phases are positioned at preset positions about the axis relative to the stator coils of the plurality of phases.
