You added a good point.
The issue from variable speed motor controls is pretty serious.
I live in an apartment that upgraded the elevator system about 2yrs
Prior my noise level was s0 or s1
Noise level now is s9 all bands! for a 30ft radius /min
Discovered the noise source is a Maganek600 motor controller. Manuf. told
me, they don't need FCC approvals because it has a Canadian rating
They also told me they never had any previous complaints (right)
You all make a good point, stuff like this should never be allowed
