Japanese Patent JP7199287
Kind Code:
B2
Abstract:
To provide a brushless motor capable of suppressing magnetic flux leakage of a pole-oriented magnet.SOLUTION: A motor unit 2 has a stator 6 and a rotor core 22. The rotor core 22 is made of a magnetic material including a magnet 23, disposed radially inside teeth 12, of a polar orientation for generating magnetic poles on a surface facing the teeth, provided in a circumferential shape. The magnet has a plurality of convex portions 25, formed to be connected in an axial direction of the rotor core at equal intervals in a circumferential direction to project inward in the radial direction. The convex portions and the rotor core are in contact with each other.SELECTED DRAWING: Figure 2
