Abstract:
A stepping motor includes: a cylindrical rotor assembly disposed around the rotation axis; a stator assembly including two stator units disposed around the rotor assembly and axially coupled to each other; and a terminal structure disposed at the axial center of the outer circumference of the stator assembly. The terminal structure includes: a terminal block cluster composed of four terminal blocks; and four terminals fixed respectively to the four terminal blocks. The four terminals each include: an internal connection portion to which one of two wire ends of the winding is connected; and an external connection portion which is disposed substantially parallel to the internal connection portion and which is connected to a driving circuit disposed externally. The four terminals are arranged in a line along a direction substantially orthogonal to the rotation axis, and the internal connection portion and the external connection portion are aligned along the rotation axis.
