AmeriMexs patented Dominator AC electric motor is designed for superior performance 
with capabilities ranging from 400 to 3000 horsepower. The Dominator is used for many 
applications in the oil industry such as drilling, dredging, petrochemical, mining, marine propulsion, 
mud pumps, draw works, rotary table and top drives. Marine applications include vertical thruster 
motors, main propulsion motors, main pumps, cutter head drives, hoist, and crane duty motors. 
Features such as Kapton insulation, a superior cooling system, and 33% more copper in the rotor and
 stator than our competitors make the Dominator an industry leader when it comes to electric motor 
design. Its patented design ensures a lifetime of five times longer than competitors while 
maintaining a comparable price, which ultimately benefits our customers with a competitive edge. 
The Dominator offers the highest standard of quality and is built to perform reliably in even the 
most demanding environments where high horsepower, high torque, and low vibration are required.
