PC based Rotor Tester
MODEL: 4008RJ
The PC Based Rotor tester is the most reliable, fast and cost-effective way to detect faults in the Rotors in less than 10 seconds. This Rotor Tester can only Test small sized Rotors having stack length less than 300 mm and weight less than 10 kgs.
ROTOR FAULT DETECTION
The Rotor tester uses the principle of electrical and magnetic effects caused by the circulation of induced currents into the bars of a rotor, which is made to turn at a constant speed, with in a magnetic field produced by a permanent magnet. The induced magnetic field produced by permanent magnet, acts on one slot at a time therefore the direction of magnetic field is such that the turns of a moving rotor cut the lines of force normally.The induced currents, which are proportional to the field intensity (distance of magnet from the rotor, on the speed of rotation constant) & on the rotor characteristics, produce magnetic fields, the symmetry of which enable a clear observation of the turns in the short-circuited condition. A fixed probe subjected to the magnetic fields produced by the rotor under test, provides the signals, which after being amplified, are applied to the Display. The synchronized sinusoidal wave pattern from the rotor bars is displayed on the screen. The waveform identifies typically occurring faults in the rotor bars & there is a distant correlation between the result of the inductive test of the rotor bars & the starting torque of a motor.
The Rotor Tester can easily detect the following faults in Rotor:
- Broken or interrupted rotor bars
- Poor or missing connections to the rotor end rings
- High Bar resistance
- Short circuit between Two or more Bars
- Error in the relative position between commutator and slots
- Non-uniformity between lamination of commutator
- Deviation of the Skew angle
NOTE: The Rotor Tester can identify Faults in both Aluminium & Copper Die cast Rotors.
