EMC mounting: disturbance measurement with inverter frequency converter

00:09.946 --> 00:18.503
Put into operation, the disturbances induced in the circuit loop are not delayed!

00:18.503 --> 00:34.284
Without oscilloscope, motor and drive connection: Catastrophe! We go from 4 V to 6 V peak to peak and the program of the ocillo plant on the shelf!

00:39.950 --> 00:47.477
I put back the mass and passes to the adjoining plate

00:47.477 --> 00:58.558
Much better! From 4V to c; we go down to 1.6 Volts!

00:58.558 --> 01:04.730
I increase the sensitivity of the oscilloscope

01:04.730 --> 01:19.886
The twisted is a little better, not much because the intensity is low in the vacuum motor

01:19.886 --> 01:35.445
The ground plane under the tablet also prevents it from bugging

01:35.445 --> 01:40.343
The aluminum 'shielding' tube aggravates things a lot ... As long as it's floating!

01:40.343 --> 01:46.657
As soon as it is referenced by contact: it is much better!

01:46.657 --> 02:00.100
Now I shield the power wires

02:00.100 --> 02:10.984
Floating power shield: not too much result

02:10.984 --> 02:19.312
By linking the drive side and the motor, the gain is tangible!

02:19.312 --> 02:29.216
When everything is armored, the gain becomes really sensitive
