<p>PROBLEM TO BE SOLVED: To protect a sensor (magnetic sensor), which detects the rotation position of a rotor, from being influenced by leakage fluxes from stator windings. SOLUTION: This motor 12 has a cylindrical rotor 20, a stator 19 provided on the outer circumference side of the rotor 20 with a prescribed gap and a sensor 23, which detects the rotation position of the rotor 20. The stator 19 has a stator core 19a and a plurality of stator windings 19b, which are arranged in the circumference of the stator core 19a at approximately the same intervals. A shielding plate 26, which shields fluxes leaking from the stator windings 19b to the sensor 23, is attached to the stator core 19a. By attaching the shielding plate 26, a closed loop is formed of the path starting from the stator winding 19b→shielding plate 26→stator core 19a, so that leakage fluxes are not applied to other components.</p> |
