In this technique, two stators are activated at a time instead of one in a very less time period. This will magnetize & demagnetize the stator to move the rotor forward. In this technique every phase otherwise stator next to each other will be triggered one by one alternatively with a special circuit. It is an old method and not used much at present but one has to know about this technique. The basic method of driving a stepper motor is a single excitation mode. There are several methods to drive this motor, some of them are discussed below by taking an example of a four-phase stepper motor. Stepper motor driving techniques can be possible with some special circuits due to their complex design. In this way, the stators are activated in a series to revolve the stepper motor. Once the stators of this motor are energized then the rotor will rotate to line up itself with the stator otherwise turns to have the least gap through the stator. The poles of the stator as well as the rotor don’t depend on the kind of stepper. In this motor, there is a soft iron that is enclosed through the electromagnetic stators. So this is the fundamental working principle of this motor. Now rotor in the motor will start to move with the rotating magnetic field of the stator. Once the supply is provided to the winding of the stator then the magnetic field will be developed within the stator. It includes a rotor which is made with a permanent magnet whereas a stator is with electromagnets. The stepper motor working principle is Electro-Magnetism.
