EM was founded as a service shop in 1891. Manufacturing began in 1897. For over 100 years, EM has earned its reputation for designing, manufacturing, and servicing large, custom-engineered electrical motors and generators in the U.S. and worldwide. EM services oil and gas refinery, chemical, utility, general industrial, pulp and paper, and municipal markets. EM has earned a reputation for design innovation by developing the :

• First high-starting-torque synchronous motor.
• First solid-state brushless excitation system.
• First vertical, self-contained hydrogenerator.
• First automatic starting system for synchronous motors.
• First large 2-pole induction motor design to operate below its first critical speed.

EM pioneered its Duraguard insulation system in the early 1970's. Today, EM's Duraguard process, using epoxy resin tape, and vacuum/pressure impregnation (VPI), is recognized as the benchmark of the insulation system for large machines. EM's installation list includes over 250,000 units and over 1.5 million HP installed throughout the world.

Applications include synchronous and induction motors to drive pumps, reciprocating and centrifugal compressors, blowers, fans, and ball mills. EM generators are driven by a wide variety of gas, steam, and hydro turbines, and reciprocating engines. EM's line of magnetic-drive, variable speed couplings are used with fans and pumps to 2500 HP.
