EC100 series
Two cooling structures; the choice depends on where the cooling airflow comes from. The workhorse product series of the mid-power band.

EC100 series overview
EC100 is offered in TEAO and TEFC cooling arrangements. They differ in cooling-air source; the TEFC fan drive and continuous low-speed capability still require factory confirmation.
- Supply
- 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
Cooled by the load, no fan of its own
Totally Enclosed Air-Over. Cooled by the airflow of the driven equipment itself, with no fan of its own — suited to applications that already move air, such as direct-driven axial fans.
What sets this version apart
The main difference from the TEFC in the same series is the source of cooling airflow. TEAO depends on load-side airflow; minimum continuous speed, load and thermal limits still require duty-specific confirmation.

| Rated power | To confirmDThe overview states 3–4.5 kW while the detail table contains 5.5 kW and 750 rpm rows; the range must be reconciled |
| Speed range | To confirmDThe detail table shows 750 rpm, absent from the overview; confirm whether 750 rpm is a production rating |
| Rated torque | To confirmDThe available material gives power and speed ranges, not paired operating points; range extremes cannot be combined into rated torque |

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.
Carries a cooling fan; drive arrangement to confirm
Totally Enclosed Fan-Cooled. It carries a cooling fan, but the available material does not state whether that fan is shaft-mounted or independently driven; continuous low-speed capability must be confirmed from the fan arrangement and thermal data.
What sets this version apart
It adds a cooling fan and shroud over the TEAO, reducing dependence on load-side airflow. The TEFC name alone does not prove rated cooling at low speed or near stall; the fan drive and permitted operating range must be confirmed.

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.

The legacy performance table shows the data structure only; unconfirmed fields such as weight are not selection inputs.
From the standalone English site cache, compiled 2026-09-20, unconfirmed by the factory and not publishable. The torque column is verified as derived from 9550·P/n, not measured; the weight column is non-monotonic — at 1500 rpm the 3 kW reads 18.5 kg against the 4 kW at 16.4 kg — and needs factory review.
Ventilation duties for the EC100
Suitability for a specific application depends on airflow, static pressure, speed, cooling and installation conditions. Submit the actual duty for engineering review.
