Today, modern technologies tend to develop rapidly. The application of advanced inventions, principles,
systems and approaches allows to simplify the production process, reduce the cost of manufacturing finished
products, replace monotonous manual work with automated systems and devices. The basis of the power drive of
such systems are electric motors: with permanent magnets, direct current, stepper, etc. When developing any
electromechanical system, the task of choosing the type of drive motor, its parameters and characteristics. This
article is devoted to the choice of such an electric motor for an electromechanical system for three-dimensional
plastic printing. As a result of comparative analysis of parameters and characteristics of different types of motors,
it is established that bipolar stepper motors are optimal for use in low-power and small-sized systems for threedimensional printing. This is due to the simplicity of their design, reliability and low requirements for nominal
and maximum torque.
