Custom 3 phase specialty electric motor Custom 3 phase specialty electric motor A customer needed more horsepower in the same frame size as their original motor. They also needed a spare motor to match. Originally their motor was 450 HP, they needed to increase it to 600 HP.

Louis Allis was able to design a new motor with the horsepower they needed and the same size frame as the original motor. Louis Allis was also able to salvage their old motor as a spare.
