Direct Drive Applications
Laser Processing — Direct Drive Applications
Laser cutting, welding and marking require motion axes with high dynamics, constant velocity and high path accuracy. Iron-core and ironless linear motors directly drive gantry and scanning axes — backlash-free and without hysteresis — ensuring a smooth laser path; RDDS rotary direct-drive subsystems serve rotary-axis applications in the laser industry.
Drive Challenges in Laser ProcessingDrive challenges in laser processing
Gantry and scanning axes impose strict requirements on dynamics, constant velocity, path accuracy and high thrust.
High-Dynamic Gantry AxesHigh-Dynamic Gantry Axes
Laser processing heads require fast start-stop and high acceleration to boost throughput. L1 / L7 iron-core linear motors provide high acceleration/deceleration capability and speed beyond conventional motors, directly driving gantries and cross slides.
Constant Velocity & Path AccuracyConstant Velocity & Path Accuracy
Cutting and welding quality depend on a constant feed rate. The L1 series has excellent constant-velocity behavior, and UPLplus ironless motors have no cogging force, moving smoothly along the path to avoid machining defects caused by velocity fluctuations.
High Force & StiffnessHigh Force & Stiffness
Large laser and waterjet cutting machines require high thrust to drive heavy gantries. L7 water-cooled iron-core linear motors deliver peak force up to 24,313 N with high static and dynamic load stiffness, reducing power loss by up to 50% at the same thrust.
Rotary Axes & Maintenance-FreeRotary Axes & Maintenance-Free
Tube cutting and 3D laser processing require rotary axes. The official RDDS rotary direct-drive subsystem applications include the laser industry, providing ready-to-use rotary axes; all direct-drive motors are contactless, wear-free and maintenance-free, ensuring stability during long continuous processing.

Typical Applications in Laser ProcessingTypical applications in laser processing
Precision laser micro-machining — thin-glass cutting, PCB repair and TGV through-glass-via drilling — share the common requirements of micron-level XY positioning accuracy, constant feed rate at high speed, and "position-synchronized output" that triggers laser pulses precisely by travel distance. UPLplus ironless and L1 iron-core linear motors provide cogging-free, low-moving-mass, fast-settling high-dynamic positioning, paired with Z-axis short-stroke actuators (LDDS / LRAM) as fast focusing / press-down axes, ensuring machining-point consistency, edge quality and yield.
