I want to know the answer to the following question:
What does the outer housing of a miniature motor resemble?
All the background I'm provided with is that "Miniature motors resemble the structure in the illustration, except that they have at least three rotor poles (to ensure starting, regardless of rotor position) and their outer housing is a steel tube that magnetically links the exteriors of the curved field magnets.". Is that enough to answer the question?
