According to the present invention, a motor position sensor is disclosed. According to an aspect of the present invention, the motor position sensor comprises: a housing, wherein a shaft installed rotatably is disposed in a central portion of the housing; a magnet unit installed at an end of the shaft and having an N-S pole disposed in a direction perpendicular to a rotation axis of the shaft; a circuit board disposed perpendicular to the shaft; and a magnetic element module mounted on the circuit board, disposed on an axis of the shaft, spaced apart from the magnet unit, and including at least three magnetic elements for sensing a magnetic field. The at least three magnetic elements detect different signals with respect to a magnetic field of the magnet unit.
