Abstract:
1. An anti-separating structure of a sensing magnet for a motor, the structure comprising: a disk-shaped plate including at least one coupling hole with a predetermined size of diameter; and a sensing magnet placed on a top surface of the plate, the sensing magnet being surface-contacted with the top surface of the plate; wherein the sensing magnet comprises a protruding lug that includes a first protruding portion and a second protruding portion, wherein the first protruding portion protrudes axially to fill each of the at least one coupling hole with a first diameter and the second protruding portion protrudes radially to have a second diameter greater than the first diameter, the second protruding portion being in surface-contact with a bottom surface of the plate, and wherein the predetermined size of diameter of the at least one coupling hole is constant along a depth of each of the at least one coupling hole.
