With more than 100 years of experience, Louis Allis has a valuable portfolio of legacy designs and projects at its disposal. Louis Allis utilizes these legacy designs to provide the following:
- Duplication of legacy Louis Allis motors and generators
- Modification of legacy machines
- Provision of data including performance information for legacy products
- Provision of spare parts information
Louis Allis can design and build a "Fit and Function" replacement for any large or specialty electric motor regardless of the original motor OEM.
- Reverse engineering services
- Providing on-site engineering to collect critical information required for building a "fit and function" replacement
- Opportunity to incorporate any design improvements or modifications when building replacement motors
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. We were able to bump up the horsepower, save them downtime, and save them from having to purchase a second new motor.
