Introducing the "DOMINATOR"

   AmeriMex's patented Dominator motor is an AC electric motor with capabilities from 800 to 3000 horsepower. It is used for many applications in the oil industry such as drilling motors, mud pumps, draw works, rotary table and top drives. It is also used for marine propulsion, dredging, petrochemical and mining applications and is built to withstand the harshest of environments. Our superior cooling system, Kapton insulation, and amount of copper in the rotor and stator CKT ensures that AmeriMex Motor and Controls leads the way in electric motor design for all industries. Our unique, patented design lasts 5 times longer than our competitors while maintaining a comparable price, giving AmeriMex a competitive edge.
