Areas of application:
3D Printing: 20mm hybrid stepper motors can be used for motion control in 3D printers to drive the print head, stage and axial motion system.
Automation equipment: These stepper motors are commonly used in automation equipment, such as automatic packaging machines, automatic assembly lines, automatic handling robotic arms, etc., for controlling precise position and speed.
Robotics: In the field of robotics, 20 mm hybrid stepper motors are used to control the joint movements of robots for accurate attitude and position control.
CNC machine tools: These stepper motors are also used in CNC machine tools to drive precise movements of tools or tables for high precision machining.
Medical equipment: In medical equipment, 20mm hybrid stepper motors can be used to accurately control the movement of components in medical equipment, such as surgical robots and drug delivery systems.
Automotive equipment: In the automotive industry, these stepper motors can be used to control the position and movement of automotive components, such as window lifting and lowering systems, seat adjustment systems, and so on.
Smart Home: In the smart home field, 20mm hybrid stepper motors can be used to control the opening and closing of curtains, rotating cameras in home security systems, etc.
These are just some of the common application areas of 20mm hybrid stepper motors, in fact, stepper motors have a wide range of applications in various industries and fields. Specific use scenarios also depend on their particular specifications, performance and control requirements.
Advantage:
Accuracy and Positioning Capability: Hybrid stepper motors offer high accuracy and positioning capability for fine stepping motions, often with low stepping angles such as 1.8 degrees or 0.9 degrees, resulting in more precise position control.
High torque and high speed: Hybrid stepper motors are structurally designed to provide high torque output and, with the right driver and controller, high speed. This makes them suitable for applications that require both high torque and high speed motion.
Controllability and Programmability: Hybrid stepper motors are an open-loop control system with good controllability. They can be precisely controlled at each step of motion by the controller, resulting in highly programmable and controllable motion sequences.
Simple Drive and Control: Hybrid stepper motors have relatively simple drive and control circuitry compared to other types of motors. They do not require the use of position feedback devices (e.g. encoders) and can be directly controlled by appropriate drivers and controllers. This simplifies system design and installation and reduces costs.
High reliability and stability: Hybrid stepper motors offer high reliability and stability due to their simple construction, small number of moving parts and brushless design. They do not require regular maintenance, have a long service life, and provide stable performance with proper use and operation.
Energy efficient and low noise: Hybrid stepper motors are energy efficient, providing high output torque at relatively low power. In addition, they typically operate to produce lower noise levels, giving them an advantage in noise-sensitive applications.
