Washing machine drain pump motor type

AI Thread Summary
The discussion centers on the type of motor used in a washing machine drain pump, specifically questioning the absence of brushes. It is suggested that the motor is likely an induction type, possibly a Shaded Pole motor, known for being inexpensive and low-maintenance. The efficiency of these motors is noted to be low, but they are reliable for the short operational lifespan of washing machines. A resource link is provided for further understanding of AC motors. Overall, the conversation highlights the practicality of using induction motors in this application.

Brush motors are a lot of hassle for that sort of application. It will almost certainly be an induction motor and the ones I've seen looked like Shaded Pole types. Not very efficient but trouble free and cheap and they don't run for long over the life of the machine.

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...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

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...
