Stepper motors or stepping motors working principles is using the magnetic properties between numerous stator and rotor teeth. The pulse signal can determine how fast the dipole of the magnets change so we can further control the rotation of the stepper motor.
Stepping motor has a rated voltage and current. A typical case like stepping motor NEMA 23 (stepping 56 type) might have a rated voltage of 2.9 Volts and a maximum current of 2.0 Amps. It means if you hook it up to 2.9 Volts it will draw 2.0 Amps.
If you run it at a higher voltage it will consumptive more current and get overheat. That’s why we don’t suggest customer hook motors straight to a voltage source. we don’t suggest you use a stepping motor driver. Stepping motor drivers control and regulate the current. If you hook it up to 10V, even the motor try to offer more current, but the stepping motor driver will change away from using frequency pulses to limit the average current.

◎Rotation speed: A stepper motor can rotate proportionally to the input signal, as a result, it can be operated without any feedback mechanism. With a higher frequency of incoming pulse, the rotation of the motor would be continuous and its operating speed also increases. Since the frequency of the input signal can change the angular speed, out stepper motor can be decently customized to a very wide range of commercial applications.
◎Vibration less: Unlike the other motors activated by the friction between teeth, the magnetic interactions of hundreds of stators and rotors allow the motor to rotate in 1.8° in every step. Frictionless operation means no vibration during the rotation, which is an important property of industries like semiconductors or advanced electronic devices.
◎Accurate positioning: The average error of positioning of a stepper motor is 4%, and attribute to the characteristic of the magnetic mechanism, the positioning error will be regulated in every step. Through the feedback of position sensor, you could control the torque and speed with ease. The precision of the operation is especially significant to the repeatable working steps process.

That’s why stepping motors are used in various types of equipment for lots of applications like 3d Printer, Laser device Printer, CNC Router, Engraving, Industrial Application, Food Machine, Automatic, Production Line, Milling, Lathe, etc.
