Cast Aluminum Rotor Tester For Compressor Pump Motor Quality Checker WIND-RT-1
(1) Quick Details
This cast aluminum rotor tester is used for determining blowholes, residues, thin strips, breaking, lack of
casting etc. Defects for squirrel-cage rotor in production casting process.And it can also test conducting
bar internal short circuit and poor performance caused by materials properties Differences.
Rotor manufacturer. This motor rotar tester is necessary equipment for Rotor manufacturer in quality
control.
(2) Advantages
1. Dedicated testing machine for judge rotor quality
2. The machine operation is simple and easy
3. Can test aluminum diecasting rotor with or without shaft
(3) Ask and Answer
Ask:
Why the waveform next to the AC induction motor diecast rotor broken bar of will become larger by tester?
Answer:
When cut magnetic lines, the broken bar of aluminum die casting Rotor doesn’t produce induced current,
So for the next bar of cast-aluminum rotor, the current is abrupt.
When Browhole (Porosity) occur, the bar is thin or too slim,
Porosity and sand holes standard should be defined by user as they are common.
(4) Test Item
1. Broken bars, tool slim bars
2. Porosity, sand holes,residues on bars,undercasting
3. Declination error,internal short circuit in bars
4. Alignment of core with bar
5. Improper end ring (Extra cost needed)
