Drew, help me out here. I can’t remember what the electronic part that’s wrapped in some kind of wire or coil is called. ?? On the tip of the tongue damn it.
Well anyway .... the person who drove us from the desert to LAX this summer, worked for a time for some company who repaired these things. As we drove past mile after mile of those windmill thingys, she told us that when the motors had to be rewired(?) or they had to rewind something ...??? well she said each one cost a small fortune to redo whatever it was that I can’t recall the name of now. It’s an electrical part. Anyway, they cost as much she said as they were supposed to save and it was a laugh that ppl bought into it all. She said her eye got opened on that issue from her experience.
HUH? If properly designed and installed the windings of the generators should literally last for decades. But then, that’s the way an American engineers would design them.
Is anyone here surprised? The Democrats and Obama seem determined to undermine U.S. prosperity anyway they can.
A coil is a wrapping of wire around a non-conductive core.
An electromagnet is a wrapping of wire around a conductive ferrous core.
A transformer is two wrappings of wire around a conductive ferrous core, one wrapping on each side. It’s the electromagnetic flux that changes the voltage, since one side has less wrappings than the other.
A balun is essentially half of a transformer. Coils on one side only.
A choke is a form of a balun.
A open coil resistor is also a wrapping of wire around a non-conductive core.
A motor is a cross between a transformer and an electromagnet.
Windmills generate electricity because the windmill’s propeller spins an armature, which spins in a magnetic field. This makes pulses of electromagnet flux, which are picked up by coil wrappings and taken away as electricity.
Feed the gizmo electricity and the middle bit spins: that’s a motor. Spin the middle bit and electricity comes out the wires: that’s a generator. They are nearly the same device, just used backwards. You can actually generate electricity by moving the diaphragm on your stereo speakers. Because the diaphragm is driven ... by a non-rotating form of motor!
Windmills are not without their dangers as well....
Uh, is there any chance that the bearings, control sysem or the windings were made in the People’s Republic of China?
