What is Stepper Motor?
-Stepper motors are DC motors that move in discrete steps. They have multiple coils that are organized in groups called "phases".Stepper motors are DC motors that move in discrete steps. They have multiple coils that are organized in groups called "phases".


What  is a stepper motor for?
-Stepper motors are DC motors that move in discrete steps. They have multiple coils that are organized in groups called "phases". By energizing each phase in sequence, the motorwill rotate, one step at a time. With a computer controlled stepping you can achieve very precise positioning and/or speed control.

Is a stepper motor AC or DC?
-In other words, DC can be switched to the motor so that it sees AC. As the windings are energized in sequence, the rotor synchronizes with the consequent stator magnetic field. Thus, we treat stepper motorsas a class of AC synchronous motor.


What is the working principle of stepper motor?

-Working of Permanent Magnet Stepper Motor: The operation of this motor works on the principle that unlike poles attract each other and like poles repel each other. When the stator windings are excited with a DC supply, it produces magnetic flux and establishes the North and South poles.
