Abstract
This motor includes a stator whereupon a plurality of magnetic poles are arranged at first prescribed intervals on the outer circumference section, and a rotor which is rotatively arranged on the outer circumference of the stator by having a prescribed space in between and has permanent magnets magnetized to different polarities at second prescribed intervals. The magnetic pole of the stator forms an extending section which extends from a magnetic pole base section in a direction parallel to the permanent magnet, and the extending length of the extending section in the direction parallel to the permanent magnet is same as that of the magnetic pole base section in the direction parallel to the permanent magnet or shorter.
