Abstract

A motor includes a stator having a stator iron-core on which a winding is wound, a rotor having a rotary body holding a permanent magnet opposed to the stator along a circumferential direction and a shaft joined to the rotary body such that it extends through the rotary body at the center, bearings supporting the shaft, two conductive brackets for fixing the bearings, and a printed circuit board on which a drive circuit for driving the winding is mounted. A dielectric layer is provided between an outer wall of the rotary body and the shaft, the two brackets are electrically connected together, and a capacitor is connected between the stator iron-core and the brackets for adjusting impedance.
