1. Stepper motor, principle of operation
A stepper motor is a brushless device with a synchronized principle of operation and multiple windings. The operation of the motor is based on the gradual activation of the rotor windings, which provide the movement, i.e. the rotor or its fixed steps. The rotation of the stator and rotor occurs due to the magnetic flux. The rotational force of a stepper motor is proportional to the strength of the magnetic field, which corresponds to the number of turns of the windings and the current. Thus, a stepper motor is a device that converts electrical impulses into mechanical motion. The motor design consists of leads, shaft and a circular housing.

2. Types of Stepper Motors
You can buy stepper motors by choosing from various types of devices. The following types of stepper units are sold in the modern market:

Hybrid motors
Variable reluctance motors
Constant reluctance motors
Variable resistance motors rotate freely and have three or four windings. Permanent magnet motors are rotationally resistive and have two windings. The hybrid engine is a modified model of the constant reluctance motor.

3. Fields of application
The purchase of stepper motors for use in many fields of technology is appropriate. Stepper motors are used for continuous motion drives or drives for mechanisms with start-stop modes. The purchase of stepper motors for CNC machine tools is appropriate because they are controlled by a series of electrical impulses. Stepper motors are used in the operation of computer storage devices and optical disk reading devices due to the ability to precisely position them. The high reliability and good technical performance of shaft motors explain their wide application in the military industry. In addition, they are used in automobiles, various production equipment and household appliances.

4. Advantages and disadvantages of use
Before buying a stepper motor, you should consider the advantages and disadvantages of its use. The undoubted advantage of stepper motors is the rotational accuracy; the rotor rotates to a specific level when the charge hits the winding. The advantage is the opportunity to purchase CNC stepper motors at a relatively low cost. Stepper motors are ideally suited for equipping technical process automation systems. Stepper motors are capable of fast start/stop and restart modes. They are characterized by highly precise step sizes and high repeatability without increasing the percentage of error per rotation. Ability to run at lower speeds. Another advantage of stepper motors is the lack of brushes in their design, which extends their life and increases reliability.

Disadvantages include the ability of the stepper motor to slip. This problem occurs when the software is installed incorrectly, the speed goes into resonance, or the total load level is exceeded. To prevent the possibility of slippage, feedback sensors are installed on the motor to control motion and rotational speed. At the same time, the sensors only signal that there is a problem; to eliminate the problem, it is necessary to stop the production process. To prevent slippage, it is recommended to purchase a more powerful CNC stepper motor. This will avoid the problem of stepper motor slippage and take full advantage of all its benefits.
