Patent number: 11448523Abstract: A sensor device may include a rotor, a stator disposed outside the rotor and a sensor module disposed outside the stator. The rotor may include a sleeve and a magnet coupled to the sleeve, and the magnet may be disposed inside the sleeve. The sleeve may include a fixing part which protrudes from an end of the sleeve and is in contact with the magnet. The sleeve includes a second body, and a third body. The second body is disposed to cover an upper surface of the magnet, and the third body is disposed to cover an outer circumferential surface of the magnet. The magnet is disposed between the shaft and the third body, thereby providing an advantageous effect of increasing a coupling force between the magnet of the rotor and a yoke.Type: GrantFiled: August 20, 2020Date of Patent: September 20, 2022Assignee: LG INNOTEK CO., LTD.Inventor: Ho Chan Son
