<p>PROBLEM TO BE SOLVED: To provide a DC brushless motor in which starting of a rotor becomes simple. SOLUTION: The DC brushless motor comprises a base seat having a through hole formed thereat, a support 12 provided at one end of the hole of the seat, and at least one localization member 17 provided between two adjacent coils at the seat in such a manner that the member 17 is manufactured of a metal magnetic conduction material having a magnetic absorption effect. The motor further comprises a rotor 2 rotatably pivotally secured to the support 12 of the seat via a rotary shaft 21, and an annular permanent magnet 22 having N and S poles and provided at the rotor in such a manner that ferromagnetic zones are provided at the N and S poles of the magnet. Thus, when the rotation of the rotor is stopped, the magnet 22 is formed so that one ferromagnetic zone 222 in the magnet 22 approaches the member of the seat each other to be attracted to each other. When the rotation of the motor is stopped, the rotor is avoided to stop at a dead angle position in starting the rotor.</p> |
