<p>PROBLEM TO BE SOLVED: To provide a motor capable of suppressing leakage flux and improving output characteristics.SOLUTION: In a brushless motor 11, a stator 16 having a stator core 17 and windings 20; first and second rotor cores 31, 32 in which a plurality of first and second claw-like magnetic poles are formed at an equal interval on an outer peripheral parts of first and second core bases so as to be projected to the outside in a radial direction and extended in an axial direction, and while opposing the first core bases to the second core bases, the first and second claw-like magnetic poles being alternately arranged in a peripheral direction; and a rotor 21 including a field magnet 33 arranged between the first core base and the second core base and capable of functioning the first claw-like magnetic pole as a first magnetic pole and functioning the second claw-like magnetic pole as a second magnetic pole are stored in a case 12 having a bottomed cylindrical yoke housing 13 and an end plate 14 for blocking an aperture of the yoke housing 13. The yoke housing 13 has a magnetic substance part 51 and a non-magnetic substance part 52.</p> |
