Although AC variable speed drives have, in many cases, replaced these types of motors and control systems, they are often still used on grounds of cost, simplicity and reliability.

Fortress can assist you to replicate existing equipment, even where the original design data is not available and the original equipment manufacturer either no longer exists or no longer manufactures resistors.
