Frequently Asked Questions
How do IEC frames differ from NEMA?
IEC uses metric shaft diameters, mounting dimensions, and flanges (B3/B5/B14). They are not interchangeable with NEMA frames - match the IEC designation exactly.
What mounting types are available?
Foot mount (B3), flange (B5/B14), and combinations. Confirm the mounting code your equipment requires.
Are these 50/60 Hz?
Verify the frequency and voltage - IEC motors are often dual-rated; match your supply.
