1.What is a closed loop stepper motor?
A closed loop stepper motor is a stepper motor system that incorporates a feedback mechanism, typically an encoder, to monitor its position and correct for any deviations from the intended movement. This feedback allows the motor to operate more reliably and accurately than traditional open-loop stepper motors, especially under varying loads or at high speeds. 

1. Basic definition and function of integrated servo motors
Integrated servo motors integrate key components such as servo motor body, encoder, and driver to form a complete servo system. This design not only simplifies the installation and maintenance of the system, but also improves the reliability and response speed of the system. The encoder is used to detect the position and speed of the motor in real time, and the driver is responsible for receiving the control signal and driving the motor to rotate, thereby achieving high-precision position, speed and acceleration control.

1. Basic definition of closed-loop stepper motors
A closed-loop stepper motor is a stepper motor that adds an encoder to the stepper motor to achieve high-precision, low-jitter functions through position feedback and speed feedback. The closed-loop stepper motor detects the actual position and speed of the motor, compares it with the target position and speed, and adjusts the running state of the motor through the feedback mechanism, thereby ensuring that the motor's movement is more precise and stable.

1.Definition and principle of linear guide rail
1.Linear guide rail is a mechanical component used to support and guide moving parts to reciprocate linear motion in a specific direction. It can achieve high-precision linear motion under high load and can bear a certain torque load. Its core principle lies in the design of its internal structure. It consists of components such as slide rails, sliders, balls, ball retainers, and return ball grooves. The balls roll and circulate infinitely between the sliders and the guide rails, allowing the load platform to move linearly along the guide rails with high precision. This design makes the friction coefficient extremely low, enabling subtle and precise motion to meet the needs of high-precision positioning.

‌‌‌1. A brief introduction to hybrid stepper motors
Hybrid stepper motors are a type of motor that combines the advantages of permanent magnet stepper motors and reactive stepper motors. It has high output torque and high step accuracy, and is widely used in industrial automation and precision control, especially as a drive device in economical CNC machine tools. Its high precision, high reliability and good speed regulation performance make it perform well in these fields.

1. Introduction to helical planetary gearboxes
A helical planetary gearbox is a mechanical transmission device composed of a planetary gear mechanism and helical gears. The core lies in the layout of the planetary gears. The central sun gear is surrounded by multiple planetary gears, and the outer side of the planetary gears wraps around the annular gear ring, and all gear axes remain parallel. The characteristic of the helical gear is that the tooth shape is inclined at an angle to the axis, and the common angle range is between 15 degrees and 30 degrees. This design makes the gear meshing process more coherent and effectively reduces the operating noise and vibration amplitude.

1.A brief introduction to linear guide rail
Linear guide rail is a mechanical guide rail used to support and guide moving parts to reciprocate linear motion in a given direction. It usually consists of two parts: a track (slide rail) and a slider. The slider is equipped with internal circulation balls or rollers, which can achieve smooth, high-precision linear motion on the track and can withstand a certain load. ‌

1.Definition of servo motors
Servo motors are motors that control the operation of mechanical components in servo systems. They are auxiliary motors that indirectly change speed. Servo motors can convert voltage signals into torque and speed to drive the controlled object, and have the characteristics of high precision and fast response. The main types of servo motors include DC servo motors and AC servo motors.

1.Definition of CNC spindle motors
CNC spindle motors refer to electric motors that are directly mounted on the spindle of a machine tool, and are usually integrated with the spindle of the machine tool to form an integral component. This type of motor directly drives the spindle to rotate, eliminating the traditional intermediate links such as belt drive and gearbox, thereby improving transmission efficiency and processing accuracy.

‌1.Basic introduction to permanent magnet stepper motors
Permanent magnet stepper motors are motors that use the interaction between permanent magnets and electromagnetic coils to generate rotating power. Its basic working principle is to apply currents of different phases in the stator windings to generate a rotating magnetic field, which interacts with the permanent magnets on the rotor to make the rotor rotate step by step.
