Linear motion control refers to the precise management of position, speed, and displacement along a straight path. It is the foundation of modern automation, enabling machines and equipment to perform smooth, accurate, and repeatable linear movements. Whether it is a CNC machine, a semiconductor stage, or an industrial robot, linear motion control ensures that every movement is measured, monitored, and corrected in real time.
At the core of linear motion control are encoders, which act as the feedback device. They convert physical movement into electrical signals that a control system can interpret, enabling closed-loop control for maximum precision and stability.
· Machine Tools & Metalworking – Press brakes, bending machines, CNC milling and grinding machines.
· Semiconductor & Electronics Manufacturing – Lithography machines, wafer inspection, PCB assembly.
· Robotics & Automation – Collaborative robots, linear actuators, pick-and-place machines.
· Medical & Life Sciences – Imaging systems, diagnostic equipment, precision laboratory stages.
· Logistics & Packaging – Sorting machines, conveyors, and high-speed packaging systems.
· Energy & Transportation – Solar panel positioning systems, railway measurement systems.
Encoders provide the feedback signal needed for closed-loop control. They measure the linear position of a moving stage, motor, or platform and transmit the data to the controller. The controller then compares the feedback with the command value and adjusts the drive system in real time.
· Incremental Magnetic Linear Encoders
Generate pulses that represent relative movement. Simple, robust, and cost-effective, they are ideal for machine tools, bending machines, and general automation where micrometer-level precision is sufficient.
· Absolute Magnetic Linear Encoders
Provide a unique position value at every point along the scale. Even after a power-off, the system can immediately detect the true position upon restart. They are widely used in linear motors, direct-drive stages, and robotics where reliability and efficiency are critical.
· Incremental Optical Linear Encoders
Using stainless steel or glass scales, these encoders achieve nanometer-level resolution and extremely high accuracy. They are the preferred choice for semiconductor equipment, precision measuring instruments, and scientific research applications requiring the highest precision.
