Machines for rotors testing

The first in the world to make testing systems for die-cast rotors, we have produced a series of machines suitable for all sizes and production requirements. The range of machines for testing rotors, both die-cast and wound, is marked by the size (our range of machines is suitable for tests of all sizes) and the degree of automation required. In fact, our machines can be divided into two types: manual and automatic.

The electronic part for detection and analysis of the resulting curves is practically constant for all types, whereas the positioning and rotation mechanics is one of the main components that distinguish our machines. For testing rotors, Risatti has created a technology that is particularly suitable for the type of work, guaranteeing maximum strength and absence of vibrations, which could make the test imprecise. Designed individually to adapt to the requirements and features of every single product and Customer, it is the fruit of long-standing experience and of the numerous specimens made.

Another very important point, for testing rotors, is measuring the welding resistance. Also in this case, the experience built up, both in different but similar sectors, and in the specific case, has enabled us to obtain excellent results.
