Air-Cooled Permanent Magnet Synchronous Motor (EDS/EDU Series)

The EDS Series delivers high efficiency equivalent to IE4 (Super-Premium Efficiency) or above, while the EDU Series delivers high efficiency equivalent to IE5 (Ultra-Premium Efficiency) or above. High efficiency is maintained even in the partial load range, significantly reducing CO₂ emissions and electricity consumption.

The efficiency values are design values at the rated output for models with a rated rotation speed of 1200 min^-1.
In addition to losses of the motor itself, harmonic losses from inverter operation, auxiliary power consumption of the electric cooling fan, and other factors are also taken into account.

• Operating conditions during measurement: 50 Hz, 380 V, 1800 min^-1, motor ambient temperature 28.9°C
• Annual operating hours: 24 hours × 300 days
• Electricity cost: 21 yen/kWh
  (Electricity sales unit price for high-voltage corporate users published
  by the Energy Information Center, as of February 2025.)
• CO₂ emission factor: 0.000422 ton/kWh
  (Alternative value published by the Ministry of the Environment and the Ministry of Economy, Trade and Industry on March 18, 2025)

• Split-type fan cover
  The use of keyhole slots greatly improves workability.
  It also provides greater flexibility in installation conditions with minimal maintenance space.
• Grease drain scraping mechanism
  This reduces the workload required for greasing.
• Angled terminal box
  This reduces the workload required for wiring.
