    Ac Ac motor Motor
AI Thread Summary
The discussion revolves around running a monophase AC motor from a fan, with the user seeking guidance on the unexpected wiring. The user has limited experience with motors but has completed courses in Electrical Machinery. Suggestions include reconnecting the motor to its original controller to assess its torque and performance. However, concerns are raised about safety and the risks of inexperienced individuals working with AC mains projects. The thread concludes with a recommendation to seek private assistance for further help.

Hey, everyone,

I got this motor from my fan, I am trying to run it but there are a few more wires that I was expecting. Can someone please give me some light? What are all those wires and how to make ir run.

Hi Phellippe,

How much experience do you have working with AC Mains powered devices and motors? What are you hoping to do with this motor?
 
Hey, Thanks for your reply.
I don't have any experience with motors, I just have an idea about how it works, I've already done Electrical Machinery 1 and 2.
But I really don't know how to make it start from speed 0. I opened the stator and I guess its an monophase induction motor because the rotor looks like a squirrel cage rotor.
What I am planing to do? I am not sure yet, first i need to see it working to check how powerful it is
 
Hi Phellippe,

Is it possible to hook the motor back up to its original controller? Set it on high speed and it will develop all the torque it's capable of (not much). Then you can tell if it will have enough for whatever projects you have in mind. But if you can't hook it back up to the controller, post a reply and I'll try to figure something else out. Most of those motors like that are pretty similar and I'm familiar with them.

In general, we don't like inexperienced folks working with AC Mains projects. I need to close this thread, sorry. Perhaps @Jack of some trades can help you via PMs.
 
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
