Base-Mount AC Motors
Replace old base-mount motors to keep your equipment moving. Motors are rated for continuous duty and mount at any angle. You can wire for clockwise or counterclockwise rotation; instructions are included.
To use a motor with a variable frequency drive (AC motor speed control), choose a three-phase motor that’s inverter rated.
Motors with a welded base have a base that's welded to the enclosure.

Hazardous Location Base-Mount AC Motors
These motors are rated for environments where hazardous material is present. They are continuous duty and mount horizontally. You can wire for clockwise or counterclockwise rotation; instructions are included. The base is welded to the enclosure.
Motors with automatic overload protection turn off in overload conditions to prevent motor damage and start automatically after they cool.
Hazardous location environmental ratings indicate whether manufacturers have included safety features in products to facilitate their safe use in a hazardous environment. Before selecting a product for a hazardous location, ensure it is rated for your environment. See About Hazardous Location Environmental Ratings.
