Can you do the rear?

I hope you know that anything magnetic near these machines is not a great idea as it can magnetize needles etc. So would think a counter that is not magnetic would be a better idea.

I know this video is 4 years old by now, but that nozzle was way too close. You could hear how the filament feeder was clicking.

can not get the .009 backlash out with the software.

You could add more magnets to the motor to increase the production of volts...

you will need a charge controller to only allow 12-14 volts to battery...i have a small 300 watt wind turbine that does awesome with one battery for my house 12 volt led light system,i have charge controller that switches from battery to a grid tie after fully charged..

wind can move the motor faster then 500 rpms...maybe even double or triple that at 20+ mph winds.

Thanks for posting this. I have been looking for a good & inexpensive non-contact counter for our NZAK. Currently installed both the meter & sensor on the yarn mast (used silicone to mount the magnet). May later make a prettier housing as you did.

Love the proxy setup! Great way to add modern accuracy to a classic machine.

Plus diodes are only needed when hooking up to a battery. Without on, the battery would just power the motor. Blocking the voltage from the battery with a diode is what diodes are for. Rectifiers are only needed with ac generators.

Why did you rectify dc voltage? A bridge rectifier is equivalent to 4 directional diodes and used to convert ac to dc. You only simply need a single directional diode on your positive side. This allows current to pass through but not leak backwards.

6700rpm / 130vdc = 51.5 turns to make a volt. so 51.5 X 14 = 721 rpm needed to make 14 volts to charge your 12 volt battery. normal wind speed vary but in a good wind with a decent blade setup your looking at 400 to 500 rpm. simple solution : tie your blades into a larger gear almost double the size of your gear on your treadmill motor. now with that being said. your gonna want either a grid tie inverter with dump load features to protect your wind generator from being torn apart in high winds.

fukd up and scrapped two of them..ignt a year ago

that's funny. i get plenty of amps out of the mw&s pma's in winds around 10 mph with these crappy windy nation blades. after i switched i get faster start up, so i figure higher amps will also follow. i guess i'll see soon enough.

i have four sets of windy nation 80 inch wind grabber blades. trust me you don't want them. they aren't that great. i'm taking them off my pma's this week. i'm putting on a set of mw&s 11 blade raptures and falcon blade on my regular pma's and thier 80 inch falcon blades on my super renegade pma's. the angles on thier blades are to steep. they start up in low winds but they don't ever get a very high r.p.m. power is limited by thier blades.

Fearless thinker is so full of shit. He keeps talking real world. lol. type into youtube search bar "windy nation ripoff".

I've installed a treadmill motor as my generator. However, it is virtually useless since it can only generate around 6-10 volts during strong winds. It managed to hit around 18 volts during extreme weather but so inconsistent. I thought that I've just wasted my hard earned money since can't find any difference in my electrical consumption. I've used a grid-tie inverter to feed such juice the grid but it so disappointing. Voltage below 12 volts is rubbish as to my treadmill motor

@TheBillythekid2010 Why would anyone buy one of these from windy nation. I seen them for sale at DollarTree. Not everything in there is a dollar but for $3.50 it makes an ok door stop.

@TheBillythekid2010 Everyone knows this already. It's even set in stone by fearlesstinker himself with his flickershow of the motor. He'll deny they are refurbs all day long. This is why i call him a liar pants on fire. Ha ha. Now he thinks I'm Jeff. I think he lives in the twilight zone. oooh look behind you fearless. I'm not as smart as Jeff to be him anyway but I'm not afraid to say it and I'm not jealous, just better looking. ha ha

Oh the great Fearlesstinker speaks. All hail the wizard of oz. snoooorrr

How many watts was the lathe taking in this video?

junk

Buy manufacturer/refurbisher direct from website: effsun why pay retail?

FOCUS?

This motor needs a furling tail as to not overheat. The problem is that if your wind turbine tower is not periodically checked for level then the furling system is no good and will cause a breakdown from heat buildup. This problem is not repairable if you cannot get a similar stator winding. If you decide to get one ask the seller if they also sell replacement stator cores. If they do not then you would have to order one from china if you can locate them.

check out jeffmolly1 new video taking the chinese windy motor apart. no doubt it is chinese.

It's all about the gearing. Personally I would setup many motors off a geared or belt driven setup. What you want to do is create a torque generating windmill, whatever that means for your application and environment (e.g. low wind means larger blades and more of them, high wind means fewer blade and fewer of them required). Anyway, create your torque generating wind turbine and then use a belt system to turn many generators like the one you have above, a VAWT would be perfect.

@leamyvideo yeah but you like them!

@leamyvideo The AWEA is a joke. if you think it is not run by the old windturbine companies you are fooling yourself. You know the guys who sell their turbine in home depot etc...

although this conveyer motor can be used as a wind motor it is quite heavy. it would need a heavy tower and mounting system. car alternator type turbine motors will always have available replacement parts from local auto parts store for many years to come. Also an open pma can breathe and stay cool equaling more power like superconductors. The car alternator has been used since they were created early in the century and time proves reliability. besides , this pma is made in china. thanks

@wyattlisadana Actually, that is not the front bearing. In this video, the back bearing is shown. With respect to your question: The front bearing is sealed. Additionally, the back bearing is also sealed.

@TheBillythekid2010 I disagree with your claim that sealed PMA's overheat in high winds. The aluminum cooling fins on the body of the PMA allow for exceptional heat dissipation. Aluminum has excellent thermal conductivity and the increased surface area of the aluminum fins further aids heat dissipation. I would argue that a well designed, robust PMA needs to be sealed to protect the insides from corrosion. Besides car alternators, I don't know of any open/unsealed PMA's? Do you?

Yeah treadmill motors are just not for any wind application. We should just leave them on the treadmills. ha ha. Nice lathe setup.

I don't think those front bearings are sealed. Are they?

Thanks for the video, I was hoping someone would pull one apart, regards Nigel, aka Doc Cox

You will HAVE to gear those type of motors up with a chain sprocket setup and use large blades for large torque,low rpm of the blades..same design the large GE ones work except they use a gearbox. If you can find a 5:1 gear head that will fit,that will be perfect.

with the new grid tie inverter power will not travel back to the grid, untill ac current is restored. the grid tie inverter does shut down. hope this helps. Robert
