1. A stepping motor comprising:
a housing; a stator assembly disposed inside the housing; a rotor that is rotatably disposed inside the stator assembly and includes a rotation shaft, and opposite ends of the rotation shaft are supported by the housing; and a sensor portion that is disposed inside the housing and detects a magnetic field of the rotor, wherein the sensor portion is disposed at a position that is spaced apart from the top end of the rotor, and the position is at an intersection of a center line of an upper pole piece of an upper yoke of the stator assembly, a straight line passing through a center of the rotor, and a tangent line of an outer diameter of the rotor.
