Hydraulic-Electric Analogies: Stepper Motors (.PDF Download)

June 30, 2016

An internet search for hydraulic stepper motor will generate at least one patent on that subject. The principles explained therein are simple, and when carried to their most general concepts, can help understand ac electric motors and the rotating field used to propel either a magnetized rotor (synchronous motor) or the counter-field from current induced into an induction motor rotor...
