The largest product series offered

The EC112 product series integrates a PM synchronous motor and controller for high-volume negative-pressure fans and similar high-load ventilation equipment. It is the largest of the three series; the power band itself is contradicted between the legacy overview and detail tables, so the specification below leaves it open until the factory confirms.

What sets this version apart

EC112 is the largest product series in the available material, but no verifiable data establishes a match to a 58-inch fan or any specific duty point. Suitability requires selection against airflow, static pressure, impeller and installation conditions.

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.

Placeholder
EC112 TEFC outline and mounting drawing

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.

S-03Materials & performance

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

  • MagnetNdFeBBStated in the shared product features on all five versions

No verifiable insulation-class or temperature-rise data is available for this series; EC80 legacy FAQ values are not carried across series.

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.

S-04Applications

Ventilation duties for the EC112

Suitability for a specific application depends on airflow, static pressure, speed, cooling and installation conditions. Submit the actual duty for engineering review.
