I haven’t insulted anyone. You did. Get over it.

When you follow the link I posted:

This number shaft diameter. 7.25mm is ROAR spec rotor rule. 5.00mm use to Modified motor. thin shaft more magnet mass. more torque
In other words, there is a difference but you can not exchange the one with the othe due the different shaft diameter.

I bought an EMF detector similar to this here to test my 540 sized motors:
https://www.amazon.com/ERICKHILL-Rec.../dp/B08BLJM28J

I got more accurate readings my removing the rotor and taking the highest reading when slowly rotating the rotor as the readings are not static. I found it useful to periodically inspect with the EMF to see the readings degrade over time and know when it was time to replace the motor.

No 2 rotors ever got the same reading even from the same brand!

The only way to know for sure the strength is to use a meter

YES!


I never had any proof but we went on a "ghost tour" in Breckenridge,CO a few years back before the COVID shutdown and the lady giving us the tour gave us EMF detectors while sharing the ghost stories along the tour. Long story short, nobody else's EMF was going off but my wife's was the only one flickering when the tour guide mentioned that the ghost named "Silvia" was a clean freak. The room upstairs was rented out specifically because it's haunted by Silvia who is known to fold clothes and turn on the water over dirty dishes, etc... turns out my wife is a clean freak as well which Silvia was letting her presence known. As we walked up the stairs and got closer to the room Silvia (prostitute) was murdered in, the EMF slowly began to increase in readings from green to yellow and from yellow to red as we approached Silvia's door. Nobody else's EMF had a single reading unless we placed them close to a light switch or power outlet to verify they were working. As we left the property my wife's EMF slowly faded away and we all said goodbye to Silvia.

So I would later play around with my EMF where there's a place in the woods near my house that would make the hairs on my neck stand up from time to time and my EMF will pick up readings out there where there's no other electricity around, presumably supernatural but I am not a psychic so I can't confirm 100%, but my gut instinct tells me it's legit.

dang I would get some sage and find a medium to help them transition... physical threats tend to escalate as often shared on the Dead Files: https://www.travelchannel.com/shows/the-dead-files
