Abstract:
1. A magnetic inductive type position sensor, the position sensor comprising: a first rotor and a second rotor adapted to be coupled to a rotation shaft to rotate in association with a rotation of the rotation shaft and each rotor having a plurality of protrusively and circumferentially formed wing members that rotate with each rotor; a printed circuit board (PCB) arranged between the first and second rotors; a cover member disposed beneath the PCB, supporting the PCB; and a first guide member configured to connect each distal end of the wing members of the first rotor, such that lower surfaces of the wing members of the first rotor are aligned to be on a same first planar surface; and a second guide member configured to connect each distal end of the wing members of the second rotor, such that upper surfaces of the wing members of the second rotor are aligned to be on a same second planar surface; wherein the first rotor and the second rotor have different numbers of wing members.
