Ano ang mga klase ng kahusayan ng IE?

IE classes are international efficiency classification levels for electric motors defined by IEC 60034-30-1. IE1 is Standard Efficiency, IE2 is High, IE3 is Premium, IE4 is Super Premium, and IE5 is Ultra Premium. The 2014 edition defines IE1–IE4; normative IE5 limits were added in IEC 60034-30-1:2025.

Magkano ang enerhiyang maaaring makatipid sa pag-upgrade mula IE2 hanggang IE4?

For a typical 11 kW, 4-pole motor running 6000 hours/year, upgrading from IE2 (89.8%) to IE4 (93.3%) saves approximately 2,750 kWh/year. At €0.15/kWh, that's about €410/year.

Ano ang pinakamababang kinakailangan ng kahusayan sa EU?

Mula Hulyo 2023, ang regulasyon ng EU Ecodesign ay nangangailangan ng IE4 para sa mga motor na 75–200 kW at IE3 para sa mga motor na 0.75–75 kW (2/4/6 pole). Ang mga single-phase na motor na 0.12 kW pataas ay dapat matugunan ang IE2.

Nakakaapekto ba ang bilis ng motor sa kahusayan?

Oo, ang mga 2-pole (3000 RPM) na motor ay karaniwang may bahagyang mas mababang kahusayan kaysa sa mga 4-pole (1500 RPM) na motor na may parehong kapangyarihan. Ang mga 6-pole at 8-pole na motor ay may progresibong mas mababang kahusayan. Tinutukoy ng IEC 60034-30-1 ang iba't ibang limitasyon ayon sa bilang ng pole.

Ano ang tipikal na panahon ng pagbabayad para sa pag-upgrade ng motor?

Ang mga panahon ng pagbabayad para sa mga pag-upgrade ng kahusayan ng motor ay karaniwang nasa pagitan ng 1–4 na taon depende sa laki ng motor, oras ng pagpapatakbo, at gastos sa kuryente. Ang mga motor na tumatakbo nang 6000+ oras/taon na may mataas na gastos sa kuryente ay may pinakamaikling panahon ng pagbabayad.

Source: IEC 60034-30-1:2014 (Tables 3, 5, 7, 9), nominal efficiency limits for 4-pole, 50 Hz motors. IE class limits vary by pole count, frequency and rated power — do not apply this 4-pole table to 2-pole or 6-pole motors (the calculator uses separate data sets for each pole count). Limits are defined from 0.12 kW to 1000 kW; ratings above 200 kW use the 200 kW limit, and ratings below 0.75 kW have lower limits than shown here.

About IE5: IEC 60034-30-1:2014 defines only IE1–IE4 for line-operated motors; IE5 (Ultra Premium) appears there only informatively (Annex A) with a target of approximately 20 % lower losses than IE4. Normative IE5 limits were introduced later in IEC 60034-30-1:2025. The IE5 figures used by this calculator are indicative values derived from the 20 %-lower-losses target — consult IEC 60034-30-1:2025 (or IEC TS 60034-30-2 for converter-fed motors) for exact IE5 limits.
