Stepping motor with high angular resolution - has cylindrical ferromagnetic body rotated by electromagnets and has magnetic flux return bracket

摘要

The stepping motor has at least three electromagnets (2) located equidistant around a circle. A circular ferromagnetic body (1) acts as a stop. The diameters of the circular stop of the ferromagnetic body resting on the poles (3) of the electromagnets differs from the diameter of the circle formed by the poles. The ferromagnetic body is made of soft iron and is a hollow cylinder. A magnetic return bracket (4) connects the poles of the electromagnets and acts as a holder for them.
