Filed: 2001-11-09
Abstract: PROBLEM TO BE SOLVED: To provide a brushless DC motor in which a necessary torque can be obtained even without using so many magnets and which alleviates the problem of magnetic saturation or unevenness of a magnetic flux density. SOLUTION: The effective pole open angle θm of the magnet 11 at a rotor 10 is set to a range of 127 (electric angle) to 173 deg. (the same). Further, the most of a supplementary angle of the open angle θm is occupied by the bridge 14 of a magnetic material. Thus, the magnetic flux is easily crossed with the bridge 14 from teeth 21, and hence a reluctance torque can be effectively used. Particularly, as compared with the motor in which the open angle θ is set to about 180 deg. (the same), larger total torque can be obtained by using less number of the magnets. Particularly effective reluctance torque can be used by operating the motor by an exciting current having a lead phase angle of half the open angle of the electric angle of the bridge 14.
