A motor that starts well (MG1-32) but overheats (violates MG1-33) fails just as quickly as one that never starts at all.
: Outlines standardized testing methods to verify that the generator meets its nameplate specifications.

Most standard motors are rated under NEMA MG1 Part 30, which means they can handle a VFD input but with significant limitations on cable length and voltage spikes. A motor that starts well (MG1-32) but overheats
Harout closed his NEMA manual. "MG1-32 tells you when something is thinking about breaking. MG1-33 tells you how to fix it before anyone else knows it's broken. The problem is, nobody reads past the efficiency tables." Harout closed his NEMA manual
