Hey folks,
Ok, this is likely paranoia but does anyone out there worry about electro magnetic radiation from electric motors. I almost died of cancer a few years back so it’s on my mind. I scanned the Internet and after tossing out the crunchy loony toon opinions found that the research is inconclusive. Some studies show problems like childhood leukemia and brain cancer other studies show no ill effects. EMF is listed as a work place hazard but welders exposed to the highest levels of EMF have no increase in cancer. Opinions?? Thoughts??
Thanks

we may have covered this topic already, search function is your friend (cud have been another site though)

Real briefly (and this is my opinion from the research I've done) there is a hazard from high EMF's. But the levels that would cause any sort of damage would either have to be continuous over a period of years and years, or so high you would only see them in a MAJOR industrial setting, or both (i.e. standing next to one of Hoover Dam's generators, eating, sleeping, living, for a period of 5 to ten years).
Lower levels of "high" EMF's can cause certain side effects in people who are sensitive to them. But these are entirely resolved almost immediately after leaving the EMF field. Side effects include:
Skin irritation
Nauseau
Paranoia
Disorientation
General "creepy" feelings
And again, these are almost immediately resolved by leaving that area. These "high" EMF's can be found near areas where lots of computers are in use, areas where copper conduit is in large quantity over a large area, and sometimes in older homes where new wiring is often grounded to the old plumbing. Basically, a large charge moving over a large area.
All in all, there is nothing to be scared about when working with EV's as far as EMF's are concerned.

Qualitatively, the electric motor frame should act as a pretty good shield (almost a Faraday cage) compared to the conductors for the 400 or even 600 amps of current coming from the controller. The conductors are shielded, and I expect Zero or any EV maker has to engineer them to a certain standard for the application (how close they are to your body).
I think a welder would be in more danger than a Zero rider.
