DC brushless motor and DC brushless motor manufacturing method

摘要

PROBLEM TO BE SOLVED: To provide a DC brushless motor in which a position sensor can be positioned accurately to the stator, and fixed easily.SOLUTION: A DC brushless motor includes a rotor 400 formed freely rotatably about a shaft 405, a stator 301, a stator mold 300, a sensor substrate 308 having a position sensor 308a and a first welding fixing hole 308d, a substrate support member 306 having a second welding fixing hole 306d and a first welding fixing boss 306b, and welded and fixed by fitting the first welding fixing hole 308d to the first welding fixing boss 306b, and a stator mold 300 welded and fixed by fitting the second welding fixing hole 306d to a second welding fixing boss 307a.
