Verification boundary
What still needs to match
Mechanical interfaceConfirm complete NEMA frame suffix, mounting, shaft geometry, envelope, conduit-box orientation, and driven-equipment clearance.
Electrical supplyVerify voltage, frequency, phase, full-load current, starting method, protection, and available fault/current characteristics.
Duty and controlsCheck actual speed, service factor, efficiency, starts per hour, thermal duty, VFD suitability, and operating speed range.
Open enclosure environmentConfirm ventilation, ambient, contamination/drip exposure, guarding, and whether an open motor is suitable for the installation.
