EC80 series overview
Two market versions in the EC80 product series with the same power band. For compact, low-power ventilation equipment needing local speed control.
- Supply
- 1 / 3-phase 220 VAC; 3-phase 380 VAC, ±10%
- Control interface
- RS485 · 0–10 V speed reference
- Ambient
- −20 … 40 °C
- Frequency
- 50 / 60 Hz
Protections
Legacy listing: phase loss · locked rotor · surge · over/under voltage · overcurrent · temperature (confirm by controller revision)
CLegacy claim; must be verified against the actual controller revision
The most compact product series
Motor and control share one housing — for equipment with tight mounting space that still needs local speed control. EC80 is the most compact of the three product series, covering 0.375 to 2.2 kW.
What sets this version apart
Built to domestic wiring and selection conventions. It shares the EC80 product series and power band with the overseas version; differences lie in wiring and documentation, confirmed per order.

Fields shown as “to confirm” are conflicting, lack an applicable scope or lack paired operating points, and are not confirmed specifications.
Torque awaits paired operating points
T = 9550·P/n converts one paired operating point. The available material gives power and speed as ranges, so maximum power cannot be combined with minimum speed as rated torque. The real envelope waits for continuous/peak torque, base speed, controller and thermal limits.
Needs an engineering drawing carrying a revision date and drawing number: product outline, shaft diameter and length, flange spec, foot-hole positions. No drawing exists locally — the second item blocking sign-off of the product pages.
EC80 for export markets
It shares the EC80 product series and power band with the domestic version, adapted to export wiring and selection conventions. The legacy page additionally claims a higher power factor and CE compliance — both need documentation.
What sets this version apart
This is the only version carrying extra claims on the legacy site — higher power factor and CE compliance. That is exactly why both need a declaration on file before they can be stated publicly.

Materials, construction and performance information
Bearing numbers, silicon steel, magnets, coating — none of these needs a test report to verify, and each can be traced back to a supplier. To a selection engineer this layer says more than an efficiency label with no report behind it.
Materials
- BearingsFront 6305-2RS / rear 6205-2RSB
- Bearing brand0.375–1.1 kW: C&U · 1.5–2.2 kW: NSKBSplit by power band, not by version
- Silicon steel50W470B
- MagnetNdFeBBStated in the shared product features on all five versions
- CoatingImported PPG powder coatingBThe coating brand is usable; the legacy claim of 700 hours salt spray has no report and is withdrawn
- Weight7.6–13 kg across 0.375–2.2 kWB
Insulation: the EC80 legacy FAQ separately states Class F / 155 °C and a highest 98 °C value for the 2.2 kW motor. With conditions and definitions missing, they are not subtracted into a temperature-rise promise.
Performance by operating point
No point-by-point performance data exists locally for this series. Of the five versions only the EC100 TEAO was cached with a full eight points — power, speed, torque, efficiency, full-load current and weight; the rest remain images. This slot waits on an editable specification from the factory.
