Alconza is a quite successful supplier of slipring motors for Subsynchronous Cascade drives (Improved Kramer Systems) being able to deliver the complete package as well. For that task, Alconza is working with some well known companies who are manufacturers and designers of the Improved Kramer Systems.

This Improved Kramer System has proved to be a very cost effective alternative for old fixed speed systems, replacing them by this concept, which can achieve an important saving cost with a simple, reasonably cheap and very reliable solution.

Alconza only deliver the Improved Kramer System. This version has overcome all the problems and disadvantages of the Conventional Kramer Systems (Conventional Subsynchronous Cascade).

Many fans and pumps which are in operation in steel, cement plants or water works, are changing nowadays the old motors by this system. Alconza can adapt the dimensions of the new motors to the existing ones and deliver the speed regulation drive separately which allows the user to keep the old mechanical equipment.
