Rotor Broken Bar Electric Motor Testing Equipment Compressor Pump Motor Aluminum Die Casting

Compressor Pump Motor Aluminum Die Casting Rotor Broken Bar Testing Machine WIND-RT-1

(1) Quick Details

WIND-RT-1 Rotor testing machine use high-precision sensor to detect rotor signals,

Judge defects of rotor broken bar and thin bar automatically and then alarm, 

the data can be stored and printed.

(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) Technical Data

(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)

(5) 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.
