H-34 Stepper Motors Stepper Motors ■Structure of Stepper Motors ■Stepper Motors Principle of Operation The figures below show two cross-sections of a 0.72˚ stepper motor. Following is an explanation of the relationship between the The stepper motor consists primarily of two parts: a stator and rotor. magnetized stator small teeth and rotor small teeth. The rotor is made up of three components: rotor 1, rotor 2 and a ● When Phase A is Excited permanent magnet. The rotor is magnetized in the axial direction so that, When phase A is excited, its poles are polarized south. This attracts for example, if rotor 1 is polarized north, rotor 2 will be polarized south. the teeth of rotor 1, which are polarized north, while repelling the Rotor 1 Permanent Magnet teeth of rotor 2, which are polarized south. Therefore, the forces on Ball Bearing the entire unit in equilibrium hold the rotor stationary. At this time, Rotor 2
