[0025] Please see Figures 1 to 4 This embodiment of a Hall effect sensor motor includes: a stator assembly 1, an end cover 2, a Hall effect component 3, a rotor assembly 4, and a front end cover 5. The end cover 2 has a locking groove 21 formed thereon. The Hall effect component 3 is installed in the locking groove 21. The rotor assembly 4 is sleeved inside the stator assembly 1, and one end of the rotating shaft 41 passes through the Hall effect component 3 and is positioned in the locking groove 21 by a bearing 42. The front end cover 5 is covered by the rotating shaft 41 at the other end of the stator assembly 1 and the rotor assembly 4.
