About WEG Electric Machinery Company (WEM)

WEM was founded as a service shop in 1891. Manufacturing began in 1897. For over 100 years, WEM has earned its reputation for designing, manufacturing, and servicing large, custom-engineered electrical motors and generators in the U.S. and worldwide. WEM services oil and gas, power generation, nuclear, pulp and paper, mining and general industrial markets. WEM 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.

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