To provide a rotor, a motor and a brushless wiper motor, capable of suppressing demagnetization of a permanent magnet due to the interlinkage magnetic flux of a coil of a stator.SOLUTION: A rotor 9 includes a rotor core 32, a permanent magnet 33 and a salient pole 35. The salient pole 35 projects outward in the radial direction between the permanent magnets 33 adjacent to each other on the outer peripheral surface 32b of the rotor core 32 in the circumferential direction. Each permanent magnet 33 includes a coercive part 39 having a larger intrinsic coercive force than other portions, at an edge 33s in the circumferential direction.SELECTED DRAWING: Figure 3

    【課題】ステータのコイルの鎖交磁束による永久磁石の減磁を抑制することができるロータ、モータ及びブラシレスワイパーモータを提供する。【解決手段】ロータ9は、ロータコア32と、永久磁石33と、突極35とを備える。突極35は、ロータコア32の外周面32b上の周方向で隣り合う永久磁石33の間において径方向の外方に突出する。永久磁石33は、周方向の端部33sにおいて他の部位よりも固有保磁力が大きい保磁部39を備える。【選択図】図3
