Frequently Asked Questions
What makes a motor 'severe duty'?
Cast-iron frame, shaft slingers and epoxy-sealed bearings, corrosion-resistant paint, and (usually) premium efficiency with inverter-rated insulation - everything hardened for wet, dirty, high-vibration service.
Are these inverter/VFD rated?
Yes, these premium-efficient severe-duty motors carry inverter-rated insulation systems suitable for VFD operation. Confirm the constant-torque speed range for your application.
Do they meet premium-efficiency rules?
Yes - these meet NEMA Premium / DOE efficiency levels, which lowers operating cost over the motor's life.
