1.Definition of servo motor
Servo motor refers to an electric motor that drives mechanical components in a servo system. It is a controllable mechanical electromagnetic device used for electromechanical energy conversion and signal conversion. The servo motor has the characteristics of high-precision position control, speed control and torque control. It can accurately reproduce the position, speed and torque commands required by the host computer under controlled conditions to drive the load object. This type of motor is used as an actuator in the automatic control system, showing the advantages of small electromechanical time constant, strong overload capacity and high linearity. It is a key component for achieving precision motion control.

1.Overview
A five-phase stepper motor is a motor that realizes rotor movement by changing the direction of the electromagnetic field. Its rotation position can be controlled by changing the current. It has the advantages of precise positioning and fast response, and is widely used in various automation control systems.

1.Definition of hybrid stepper motor

Hybrid stepper motor is a stepper motor designed by combining the advantages of permanent magnet and reactive stepper motors. It combines the high torque of permanent magnet stepper motor and the high precision of reactive stepper motor, and realizes the complementary advantages of the two through specific structural design. Hybrid stepper motors can be divided into two-phase, three-phase and five-phase according to the number of phases. Among them, the two-phase step angle is generally 1.8 degrees, the three-phase step angle is generally 1.2 degrees, and the five-phase step angle can reach 0.72 degrees, showing a higher step angle resolution.

1. Dual output voltage of stepper motor driver

The stepper motor driver is a device that controls the forward and reverse rotation and incremental rotation of the stepper motor, and has multiple output modes. Among them, dual output is one of the common output modes. The so-called dual output means that the stepper motor driver drives two stepper motors at the same time. In the dual output mode, the stepper motor driver will have two output ports, which are used to drive two stepper motors respectively. The voltages of these two output ports can be set separately

1.Introduction
Linear stepper motor is a commonly used precision motion control device, which is used to realize linear motion control of various mechanical equipment, such as printing equipment, cutting equipment, medical equipment, 3D printers, etc. Correct selection of linear stepper motor is one of the key factors to realize motion control of these equipment. The following describes how to select a suitable linear stepper motor according to the application scenario and performance requirements.

1. Introduction
Worm Gearbox is a power transmission mechanism that uses a gear speed converter to reduce the number of revolutions of the motor to the desired number of revolutions and obtain a larger torque. In the mechanism used to transmit power and motion, the application range of reducers is quite wide. Its traces can be seen in the transmission systems of various machines, from ships, cars, locomotives for transportation, heavy machinery for construction, processing machinery and automated production equipment used in the machinery industry, to common household appliances and clocks in daily life. Its application ranges from large power transmission work to small loads and precise angle transmission. In industrial applications, reducers have the functions of reducing speed and increasing torque. Therefore, they are widely used in speed and torque conversion equipment.
