Description
1. Unboxing & Physical Snapshot
- Model & Brand: Siemens (SIMOTICS / 1FK6 Series) — Part Number 1FK6063-6AF71-1EH0
- Physical Dimensions: Frame size 63; housing length approx. 230mm x 139mm flange square profile with smooth cylindrical shaft extension (approx. 24mm diameter x 50mm length).
- Estimated Shipping Weight: 13.2 kg (29.1 lbs) (excluding holding brake variant additions) — a heavy metric requiring two-person lifting protocols and reinforced pallet crating for long-haul freight.
- What’s in the Box: 1x synchronous AC servo motor, integrated encoder connector housing, fitted shaft protective cap, factory corrosion-inhibiting wrapper, and original compliance declaration document. (Note: Power and feedback mating connectors must be ordered separately).
2. Product Introduction
Harsh automation environments demand high-performance rotational actuators capable of absorbing continuous thermal loads while resisting aggressive cutting fluids, lubricants, and fine metallic particulate. Designed specifically for multi-axis motion control applications, this permanent-magnet synchronous motor delivers high dynamic response and precise positioning accuracy under demanding duty cycles.
Mounting directly onto heavy cast-iron machine tool beds or automated robotic articulation arms, the rigid flanged architecture aligns precisely with high-precision planetary gearboxes. The ribbed cast-aluminum housing manages internal thermal dissipation efficiently without requiring external auxiliary blowers (—which is critical for maintaining sealed integrity in washdown or oily manufacturing zones).

4. Global Compliance & Industry Certifications
Regulatory compliance documentation provides asset managers with the legal assurance required for international equipment transfers and machinery safety audits. This drive component complies with stringent international electrotechnical safety standards.
- Expected Compliance Tier: CE Mark (Low Voltage and EMC Directives), UL Listed (for industrial control equipment in North America), cUL compliance, and ISO quality manufacturing certification.
- Audit Significance: The UL/cUL Listed marking ensures that internal motor windings and insulation systems meet strict fire safety and thermal endurance thresholds under locked-rotor conditions. Verify specific lot certifications with OEM.
5. Long-Term Storage & Asset Preservation Guide
Motors sitting idle in long-term warehouse inventory are susceptible to bearing brinelling, winding moisture absorption, and lubrication breakdown. Protect this asset using these maintenance guidelines:
- Store the motor indoors on climate-controlled shelving where ambient air humidity remains consistently below 60% relative humidity to prevent internal stator winding oxidation and corrosion of the encoder disc.
- Rotate the motor shaft manually by one full revolution every three months to redistribute grease evenly across the deep-groove ball bearings and prevent localized static indentations (brinelling) from the heavy rotor mass.
- Keep the machined shaft extension coated with its original factory-applied anti-corrosion wax film and wrapped in VCI (Volatile Corrosion Inhibitor) paper until final mechanical coupling on the shop floor.
6. Physical Installation Prerequisites
- Maintain a minimum clearance of 80mm around the exterior finned cooling ribs to allow unrestricted natural thermal convection currents to escape the motor body.
- Mount the motor flange to a rigid, machined metal surface using grade 8.8 or higher fasteners, applying calibrated torque specifications to eliminate mechanical misalignment and harmful harmonic vibrations.
- Connect the frame grounding terminal directly to the central machine ground bus using a low-impedance braided copper strap to mitigate high-frequency electromagnetic interference (EMI) originating from the servo drive switching frequencies.
7. Buyer’s FAQ (Logistics & Compliance Focus)
- What is the correct Harmonized System (HS) Tariff Code for global shipping?
Industrial AC servo motors are normally classified under HS Code 8501.52 (AC motors, multi-phase, of an output exceeding 750 W but not exceeding 75 kW).
- How does the Country of Origin (COO) impact international customs clearance?
The declared COO (typically European Union member states for this legacy line) directly dictates regional certificate of origin requirements and preferential tariff rates under cross-border trade pacts.
- Is specialized transit insurance recommended for this asset?
Yes. Because high-precision internal feedback encoders and balanced rotors can be severely damaged by severe drop impacts during freight transit, full-coverage cargo insurance is mandatory.
- Does this replacement motor include pre-loaded firmware?
No. As a hardware actuator containing only an analog/digital feedback encoder rather than an intelligent processor node, it does not store drive firmware.
