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.
