Title:
MOTOR AND FAN DEVICE
Document Type and Number:
Japanese Patent JP2022007783
Kind Code:
A
Abstract:
To provide a motor and a fan device for improving magnetic efficiency of the motor.SOLUTION: A motor 2 includes a stator 3 and a rotor 5. One of the stator 3 and the rotor 5 includes a permanent magnet 4, and the other includes a plurality of coils 6. The plurality of coils 6 and the permanent magnet 4 are arranged in a direction X51 along a rotation axis 51 included in the rotor 5. An axial direction of each of the plurality of coils 6 has a twisting relationship with respect to the direction X51 in which the rotation axis 51 is extending. The permanent magnet 4 has a plurality of magnetic poles including a magnetic pole to be targeted. The direction of a magnetic moment generated from the magnetic pole to be targeted has a twisting relationship with respect to the direction X51 in which the rotation axis 51 is extending so as to be along the axial direction of the coil 6 facing the magnetic pole to be targeted in the direction of the magnetic moment among the plurality of coils 6, when the rotation angle of the rotor 5 is a certain rotation angle.SELECTED DRAWING: Figure 1
