Efficiency Test Method IEC 60034-2-1
Efficiency test method IEC 60034-2-1 / IS 15999 (Part 2/Sec 1)
Applicable to:
Rotating Electric Machine: IEC 60034 is introducing to establish methods of determining efficiencies from tests and also to specify methods of obtaining specific losses.
- C. Machine
- C. Synchronous
- Induction Machine (All Size in scope IEC 60034)
- Rotary Converters
- AC Commutator Motors
- Single Phase Induction Motor
Why high efficient Motors?
- Save energy
- Reduce operation cost
- Reduce harmful greenhouse gases
