To provide a stator structure for an electric machine that has superior characteristics with regard to flux induction and cogging torque and that enables simple winding on stator teeth, and an electric machine in which a rotation position sensor is properly arranged inside.
The stator teeth 16 extend radially from the stator back yoke ring 14, and a stator pole is formed at free ends of the stator teeth 16. The stator teeth 16 are coupled with sleeves 12 which extend coaxially with a stator body at their free ends. In the electric machine, a brushless DC motor in particular which includes a stator structure and a rotor structure mutually coaxially arranged and wherein the rotor structure has a rotor body with a permanent magnet embedded inside, at least one magnetic sensor for detecting the position of rotation of the rotor is arranged on the end surface of the rotor body and directly faces the end surface.
