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.
