Brushless DC motor using permanent magnet

摘要

A brushless DC motor comprising a stator (1000) having a stator iron core (400) mounting a three-phase armature windings (U, U', V, V', W, W'), and a rotor (2000) having a permanent magnet, being disposed rotatably in the stator (1000), characterized in that the number of poles is 14, being formed of a permanent magnet, and the number of slots of the stator iron core (400) is 12, and in these slots (20-1 to 20-14), the three-phase armature windings (U, U', V, V', W, W') are mounted by concentrated winding system.
