Anti-separating structure of sensing magnet for EPS motor

摘要

Disclosed is an anti-separating structure of a sensing magnet for EPS motor, capable of applying a mechanical coupling force to a magnet and a plate to stably prevent the magnet from being disengaged to an axial and rotational direction, the structure including a plate, and a magnet formed on an upper surface of the plate and injection molded along with the plate, whereby a manufacturing process can be simplified to achieve an excellent adhesive strength.

主权项

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.
