Import Tips
• Provide detailed torque/speed curves proving AC multi-phase operation; servo motors often scrutinized for DC classification
• Declare exact output power in watts; small measurement discrepancies can trigger reclassification or penalties
• Include IP rating and enclosure type docs; NEMA standards help avoid parts classification under 8503
