ETEL LMP07-100-3TAS-229 Motor Ruler Primary Part – Linear Direct Drive

The ETEL LMP07-100-3TAS-229 is a high-precision motor ruler (primary part) designed for ETEL’s series of linear motors. This component serves as the magnetic track that interacts with the motor’s moving coil to generate direct thrust without mechanical transmission. Engineered with advanced magnet materials and precise manufacturing, the LMP07-100-3TAS-229 delivers high force density, excellent thermal stability, and minimal cogging, enabling smooth, nanometer-level linear motion.

This primary part is specifically tailored for high-performance applications where space is constrained but force requirements are significant. Its modular length allows for scalable stroke configurations, and its robust construction ensures long-term dimensional stability. The “3TAS” designation indicates a specific magnetic arrangement optimized for high dynamics and low ripple.

Key Features

• High Thrust Density: Maximizes force output within a compact envelope, enabling smaller machine designs.

• Low Cogging Force: Precision-magnetized pattern reduces reluctance forces for ultra-smooth velocity control.

• Thermal Stability: Designed to maintain magnetic properties across a wide operating temperature range.

• Easy Assembly: Pre-aligned mounting interfaces allow for quick integration into machine structures.

• Durable Construction: Epoxy-coated surfaces protect against corrosion and mechanical damage.

Technical Specifications

The LMP07-100-3TAS-229 has a length of 229 mm and a magnetic pitch optimized for high-speed operation. It generates a continuous force of up to 75 N and a peak force exceeding 200 N when paired with the appropriate ETEL coil assembly. The magnetic track is compatible with incremental or absolute linear encoders for precise position feedback. The unit is designed for operation in cleanroom environments, with low outgassing materials suitable for semiconductor applications.

Applications

• Wafer Handling: Linear stages for transferring and aligning semiconductor wafers.

• Inspection Systems: High-speed scanning stages for optical and electron microscopy.

• Laser Processing: Precision cutting and engraving tables.

• Flat Panel Display: Substrate scanning and bonding movements.

Installation and Alignment

Mounting the LMP07-100-3TAS-229 requires a flat, rigid mounting surface to ensure proper air gap between the magnetic track and the coil assembly. ETEL provides detailed alignment procedures to achieve the optimal gap, typically 0.5 to 1.0 mm, ensuring maximum force efficiency and preventing mechanical contact. The primary part can be joined end-to-end to create longer travel lengths with minimal joint gap, maintaining uniform force along the stroke.

Benefits

• Precision: Direct drive eliminates backlash and hysteresis associated with ball screws and belts.

• Speed: High acceleration and deceleration capabilities reduce cycle times.

• Maintenance-Free: No mechanical wear components, leading to high uptime.

• Cleanroom Compatible: Minimal particle generation, suitable for sensitive processes.

Conclusion

The ETEL LMP07-100-3TAS-229 motor ruler primary part is a critical enabler of high-performance linear motion. Its advanced magnetic design, robust construction, and seamless integration with ETEL coil assemblies provide engineers with a reliable foundation for building next-generation precision positioning systems.
