Smooth Motor is specialized in high precision stepper motor and customized assembly for 30 years.
In Smooth Motor, there are three types of linear motors available:
captive, non-captive, and external linear motors. Each type has its own
characteristics and applications. Let's explore the differences between
them:
Captive Linear Motor:
A captive linear motor, also known as a single-axis linear motor, is designed with a built-in linear guide system. This means that the motor and the load are integrated into a single unit. The linear guide system ensures precise and controlled linear motion while providing support and stability to the load. Captive linear motors are commonly used in applications where the load needs to be moved along a single axis with high accuracy and repeatability. They are often found in semiconductor manufacturing equipment, pick-and-place machines, and high-precision automation systems.
Non-Captive Linear Motor:
A non-captive linear motor, also referred to as a dual-axis linear motor, consists of two separate components: a motor module and a linear guide system. The motor module generates the linear motion, while the linear guide system guides and supports the load independently. Non-captive linear motors offer more flexibility in terms of load placement and system design compared to captive linear motors. They are suitable for applications where independent control of two axes is required, such as multi-axis gantry systems, CNC routers, and robotic arms.
External Linear Motor:
An external linear motor, also known as a linear direct drive motor, is a motor that operates externally to the load. The motor is typically fixed and provides linear motion by interacting with a separate linear guide system. The linear guide system is responsible for supporting the load and ensuring smooth and accurate motion. External linear motors offer high dynamics and excellent positioning accuracy. They are commonly used in high-speed applications, precision machining tools, and high-performance industrial automation systems.
The key differences between captive, non-captive, and external linear motors in Smooth Motor can be summarized as follows:
Integration: Captive linear motors have the motor and load integrated into a single unit, while non-captive and external linear motors have separate motor and load components.
Flexibility: Non-captive linear motors offer more flexibility in terms of load placement and system design compared to captive linear motors.
Control: Captive and non-captive linear motors provide direct control over the linear motion, while external linear motors rely on a separate linear guide system for load support and motion control.
Applications: Captive linear motors are commonly used in applications where high accuracy and repeatability along a single axis are required. Non-captive linear motors are suitable for applications that require independent control of multiple axes. External linear motors are preferred for high-speed and high-performance applications.
Smooth Motor offers a range of linear motors, including captive, non-captive, and external types, to cater to diverse customer requirements and application needs. By understanding the differences between these linear motor options, customers can select the most appropriate solution for their specific applications.
