PdMA Identifies Motors Exempt from the Energy Independence and Security Act (EISA) Motor Standards
Starting December 2010, the Energy Independence and Security Act of 2007 (EISA) introduced new motor efficiency requirements for manufacturers. Motors rated under 600 V must now comply with NEMA Premium standards for both NEMA and IEC frame sizes. PdMA Corporation is breaking down the implications of this regulation in a five‑part guide, and this is Part 3 of the series.
Motor Types Exempt from EISA Requirements
- Submersible motors
- Intermittent duty motors
- Adjustable‑speed motors with optimized windings
- High‑slip Design D motors
- Multi‑speed motors
- DC motors
- Single‑phase motors
- Two‑digit frames (48‑56)
- Medium‑voltage motors
- Definite and special‑purpose motors not used as general‑purpose equipment
- Motors integrated with a gear or brake assembly
- Repaired motors or those meeting repair‑standards efficiency levels
