Testing the quality of squirrel-cage rotors This test system for the detection of faults and damages in squirrel cage rotors of AC induction motors is result of years of experience of RM Pruftechnik in the field of manu- facturing, testing and maintenance of electric machines. Oftenly the users of electrical machines are confronted with rotor problems which cannot be identified with conventional test methods. With the rotor test a fast and easy fault detection is possible if the rotor is outside of the stator and its surface is readily available for special measurement sensors. Test equipment for electrical

Typical motor faults are breakage and cracks in the bars and in the endrings, voids or blowholes in the aluminium as well as poor soldering or welding connections. They lead to a reduced conductivity of the squirrel cage and therefore to a decrease of the performance or a malfunction of the motor, to overheating or noise. Rotor Tester RT1 The test waveforms for the rotor test are displayed on the front side on the integrated digital oscilloscope Tektronix TDS. This oscilloscope allows an easy and effective operation without knowledge of an oscilloscope. The needed settings are stored during...
