Technical Reference Stepping Motors ■Structure of Stepping Motors The figures below show two cross-sections of a 5-phase stepping motor. The stepping motor consists primarily of two parts: a stator and rotor. The rotor is made up of three components: rotor 1, rotor 2 and a permanent magnet. The rotor is magnetized in the axial direction so that, for example, if rotor 1 is polarized north, rotor 2 will be polarized south. Ball Bearing Rotor 1 Permanent Magnet Rotor 2 ■Stepping Motor's Principle of Operation Following is an explanation of the relationship between the magnetized stator small teeth and rotor small teeth. ●When Phase "A" is Excited When phase A is excited, its poles are polarized south. This attracts the teeth of rotor 1, which are polarized north, while repelling the teeth of rotor 2, which are polarized south. Therefore, the forces on the entire unit in equilibrium hold the rotor stationary. At this time, the teeth of the phase B poles, which are not excited, are misaligned with the south-polarized teeth of rotor 2 so that they are offset 0.72˚. This summarizes the relationship between the stator teeth and rotor teeth with phase A excited. No Offset 3.6° 0.72° 3.6°+0.72° N S N Stator N Phase A Phase B 7.2° Shaft Stator Winding Motor Structural Diagram: Cross-Section Parallel to Shaft The stator has ten magnetic poles with small teeth, each pole being provided with a winding. Each winding is connected to the winding of the opposite pole so that both poles are magnetized in the same polarity when current is sent through the pair of windings. (Running a current through a given winding magnetizes the opposing pair of poles in the same polarity, i.e., north or south.) The opposing pair of poles constitutes one phase. Since there are five phases, A through E, the motor is called a "5-phase stepping motor." There are 50 small teeth on the outer perimeter of each rotor, with the small teeth of rotor 1 and rotor 2 being mechanically offset from each other by half a tooth pitch.
