5. Magnet Yoke and Plate Dimensions

Magnet yokes and plates are available in 34 mm and 51 mm lengths with options for full and half yokes. They can be butted together for extended lengths. Key mechanical features include:

• Mounting holes for M2 and M3 bolts (DIN912 standard)
• Dowel pin holes (DIN7 2h8) for precise alignment
• Mass per meter ranges from 0.90 kg/m (magnet plate) to 1.90 kg/m (full magnet yoke)

6. Installation and Mounting

Mounting instructions, including flatness and parallelism requirements, are detailed in the ironless installation manual. CAD files for components are available for download from the manufacturer’s website.

7. Notes and Recommendations

• Continuous force values apply when the mounting surface is at 20°C and the motor is driven at continuous current; deviations require simulation tool verification.
• Maximum speed depends on bus voltage; consult the F/v diagram in the manual or online simulation tool.
• Contact Tecnotion for applications requiring speeds above 10 m/s.
• All specifications have a tolerance of ±10%.
