Die cast rotor testing: this simple, practical and effective test has been carried out by RISATTI INSTRUMENTS since 1975, for the immediate detection of the main defects found on die cast rotors.
Before illustrating the operating principle of the system, we wish to underscore the importance of conducting this test in the context of assistance and repairs, as well as, of course, in laboratory for research and in-depth evaluations of sample rotors.
Indeed, often, motor failure is caused by a failure occurred on the die-cast rotor, which, causing a lower yield with consequent greater heating of the stator winding, can lead to motor shutdown.
Therefore, it is extremely useful to have a quick and safe system to test the rotor prior to rewinding the stator which, without replacing the defective rotor, would be completely useless.
