KOLLMORGEN 620-FAN
Product Classification: Accessory — Forced Air Cooling Fan for S600/S700 Series Servo Motors
Product Introduction:
The 620-FAN is a dedicated cooling fan assembly designed for mounting on Kollmorgen S600 and S700 series servo motors to provide forced-air convection cooling in applications where self-ventilation (IC411) is insufficient. It replaces or supplements the motor’s internal fan for high-duty-cycle or high-ambient-temperature operations.

Functional Features:
- Forced air cooling — increases continuous torque rating by 20–30%
- Low noise operation — sleeve bearing design
- Drop-in replacement for motor internal fan in high-load scenarios
- 24 VDC operation — compatible with standard drive auxiliary outputs
Applicable Industries:
- High-duty CNC spindle drives
- Continuous-run packaging machines
- Warm-climate installations (ambient > 40°C)
- High-torque low-speed applications
Model Series: 620 — Cooling Fan Accessory Series
Installation Requirements:
- Mount on motor non-drive end (NDE) end bell
- Ensure airflow path is unobstructed — minimum 10 mm clearance
- Wire to 24 VDC auxiliary output on servo drive
- Verify rotation direction — airflow must exit motor housing
Usage Notes:
- Do not operate fan without motor installed — unbalanced rotation causes vibration
- Clean fan blades quarterly in dusty environments
- Replace if noise increases > 5 dB above baseline (bearing wear indicator)
