WARNING; High voltage PMA's and battery banks can cause lethal electric shock!

PMA's have no over heat protection. Please use the appropriate fuses to protect your PMA coils
Over heated PMA's are not warranted.

Design Notes:
The small Eagle wind turbine blades cannot turn these powerful model #SC super-core PMA's until the wind is going at least 15 to 25 MPH or more. A Series #SC type PMA requires a device with very solid torque characteristics like a water wheel or internal combustion engine. For wind turbines this means having at least a 7 foot diameter propeller design (hopefully born of the typical modern high speed twisted and tapered blade types). Recommended propeller sizes are 7, 8, or 9 foot diameters. A10 foot diameter just turns to slow while a 6 foot diameter propeller does not have enough of the required torque characteristics to properly push one of these little dynamo's!

SC series PMA's weigh 12 LBS. - Size 8" X 7" X 7"

Note: The SC series PMA's are so powerful we do not recommend them for use with our friction rollers unless they are for a very slow speed applications and not pulling over 20% off the PMA's total power rating. Generally speaking friction rollers work best on our standard series PMA's

The SC120 above Makes 12 volts spinning by hand or 680 volts at 6000 RPM (PFK cooling fan kit) - Please NOTE! This model has very fine wire and is easily burnt out when over heated. You must use a 10 amp fuse when doing test work with this model with an engine. For wind turbines use a 10 amp fuse to keep from overheating. Carefully evaluate and analyze heating problems before jumping to higher amperage fuses. Please note that cooling fans are also ineffective at speeds below 2000 RPM. DO NOT OVER LOAD THIS MODEL WITH HIGH AMPERAGE AT LOW SPEEDS!!!

WARNING!! Make sure you connect all PMA's to the correct battery polarity. Positive PMA to positive battery terminal and negative PMA to negative battery terminal. IF you reverse the connections you will burn out your PMA as the power rushes past the blocking diodes and melts your coils!!!

Tech notes: Do not attempt to use a pulley smaller than 60 MM - The belt tension required to keep the belt from slipping on a smaller pulley will cause excessive pressure on the front bearing shorting its life.


Pulley and Fan Kit (Sold Seperatly)
Includes a heavy duty cooling fan. Recommended for all engine, hydro and or belt driven systems. Wind turbines usually have enough air circulation not to require a fan.

WATER IN YOUR PMA

  • Our PMA's can get very hot so they need air ventilation holes
  • Rain water and snow will not harm them
  • Most people do not realize that rain water cannot conduct electricity!
  • Only water with minerals in it can conduct power.
  • However PMA's can rust so please coat them with our Marine Varnish to insure a long life!

Photo shows two of our PMA units and a customers 8 HP engine. After thousands of hours the PMA's are just NOW getting broke in and starting their 75 year projected life cycle since there are no brushes to wear out or worry about. Bearings availble at your local parts store.
(Do not forget to order a cooling fan kit!)


This advice is ONLY a guide line and is not a guarantee of cool operation since your amp load can still be to extreme for proper cooling. Don't pull more amperage then the PMA can handle. If you burn one up you own it!!! No warranties on burned up PMA's!!! All sales Final. If you are an amateur and do not understand electrical windings and how much heat they can take please don't buy one of our PMA's. If you are experienced watch for over heating and be careful.

A LARGE extra heavy duty cooling fan is Recommended for all engine, hydro and or belt driven systems. Wind turbines usually have enough air circulation not to require a fan BUT you must determine this fact by testing and observation. Specify your series #PFK cooling fan kit option at the time of your PMA order. Our PMA's are not fail safe!!! If you over load them they can burn out!!! You as the designer must watch carefully for signs of over heating. The Mfg. will not warranty any fried PMA's!!!!!!

HEAT WARNINGS:
IF you are pulling over 500 Watts without a cooling fan your PMA it will over heat! Fan kits are very important to have on ALL high amp applications!!!!--- Keeping your PMA's cooled, fused and under reasonable loads is the operators full responsibility. Monitor your PMA for excessive heating in all experimental machinery! Maximum PMA's operating temperature is 350 F. for 100% duty cycle. No warrantees on ANY burned out PMA's! They are sold in good working condition and you have to keep them cool and never over loaded regarding amperage draw. (PMA's have no over heat protection. Please use the appropriate fuses to protect your PMA coils)

A PMA RUNNING SLOW WHILE DRAWING A FULL AMP LOAD IS A DEAD PMA !!!!
Here is a buying guide to help you choose the right PMA and keep it cool.
These figure must then be matched to the power curves. This total calculation must
be done correctly or you will burn up a PMA or two as part of your learning curve.
(Expensive lessens for the inexperienced!!!!!!!!)

POWER DRAW CHART
0 to 300 Watts - Required RPM for proper cooling fan operation = 0 to 300 rpm +
300 to 800 Watts - Required RPM for proper cooling fan operation = 1400 rpm +
800 to 1500 Watts - Required RPM for proper cooling fan operation = 2500 rpm +
1500 to 2500 Watts - Required RPM for proper cooling fan operation = 3700 rpm +
2500 to 5000 Watts - Required RPM for proper cooling fan operation = 5500 rpm +
5000 to 7000 Watts - Required RPM for proper cooling fan operation = 8500 rpm +
7000 to 10,000 Watts - Required RPM for proper cooling fan operation = 11,000 rpm +
10,000 to 14,000 Watts - Required RPM for proper cooling fan operation = 18,000 rpm +
14,000 to 16,000 Watts - Required RPM for proper cooling fan operation = 25,000 rpm +

Following these figure are ONLY a guide and does not a guarantee cool operation since your amp load can still be to extreme. Don't pull more amperage then they can handle. If you burn one up you own it!!! No warranties on burned up PMA's!!! All sales Final. If you are an amateur and do not understand electrical windings and how much heat they can take please don't buy one of our PMA's. If you are experienced watch for over heating and be careful.

COSTAL & INLAND REGIONS:
If you plan to put your PMA in a salt water environment you MUST coat all metal surfaces to prevent the disaster of corrosion! Create a salt water and corrosion proof PMA with our Special Green Marine Varnish (Also comes in Clear)

5 to 8 HP engines are the most popular choice for people trying to achieve maximum results from their PMA's when utilizing internal combustion engines. A 5 to 6" engine pulley works good on 4 to 10 horse power engines and a 6 to 9" drive pulley has reportedly worked good for 10 and 18 horse power engines.

WIND TURBINE DESIGNERS HINT
When picking out a PMA the better choice is the higher voltage model. You don't want to be under powered. You MUST always exceed the batteries voltage to produce ANY net gain

DIVERSION LOAD CONTROLER
All of our PMA's produce unregulated D.C. voltage and may require a Diversion Load Controller and a Diversion Load for smaller batteries banks or non-grid connected applications.


NOTICE FOR ANY OF YOU A.E. NOVICES OUT THERE:
If these voltages seem high just remember that standard automotive alternators are usually putting out 40 to 50 volts into the 12 volt battery in your car. That's right! It won't harm the battery AS long as the battery is not FULL it can take high levels of charging voltage no problem. A lead acid battery will easily buffer high input voltages.

(You will never be able to see voltages this high because the battery pulls all power inputs DOWN to its own voltage level AND that's why you NEVER pull off the battery cables when an engine is running because your fuses, dash board lights and regulator will blow up !!!!!!! (Especially if you rev the engine! ,,,, NO battery---- NO buffer!!)

Have you every seen a battery charger that had a BOOST/START mode??? How could this work since you can't force more amperage into an electrical circuit. Amperage has to be "Demanded" by an electrical device so the BOOST/START switch on your battery charge is actually increasing the VOLTAGE to about 18 to 20 volts thereby allowing you to extract more amperage. Relax, it is normal to charge batteries with much more power than their output ratings. Only start worrying when the battery is fully charged and THEN any additional power must stop coming into it or must be dumped to keep the battery cool and from producing explosive hydrogen gas.

To make a long story short a 12 volt battery that is being charged with a wind turbine putting out 50 volts will still only read "12 volts" to a volt meter proving that the high voltage power is easily being swallowed up by the big lead plates of your battery.

A battery is basically a BIG capacitor in electronic terms. Once your batteries are fully charged you must THEN stop putting any additional power into it!


All of our PMA's produce unregulated D.C. voltage and may require a Diversion Load Controller and Diversions Load (water heater element, air heater) for smaller batteries banks, or for non-grid connected applications.

(PMA's have no over heat protection. Please use the appropriate fuses to protect your PMA coils)


TECH NOTES:    Taking apart a PMA the right way.

1)  Remove the 4 housing bolts and pull the front housing off OVER the shaft. Never pull the rear housing off first!!!!
If it is jammed or rusted use some WD-40 on the shaft and alternately tap the mounting wings with a hammer while applying pressure to the shaft with your thumb so that the stator and it's delicate wiring harness is kept in place.

2)  Now grab the exposed rotor core shaft and pull it out WHILE holding down the stator ring with your index
finger and thumb. This will take LOTS of strength!!!!! If you fail to hold the stator in place the core and stator
will be extracted together and the wires will be torn off! This is a tricky maneuver and usually takes some experience and lots of muscle!!!!!!!

3)  Once the rotor core has been successfully extracted the rectifier connections are exposed and you may unfasten the three wire nuts to safely remove the stator coil.

Warranties will be void on any PMA that is opened by a customer. Any PMA experimentation and examination is at your own risk.

WARNING; High voltage PMA's and battery banks can cause lethal electric shock

The "Oops Program" - "Oop's, I must have ordered the wrong PMA for this project!"
If you choose the wrong PMA we will rebuild it one time ONLY with a coil of higher or lower amperage or voltage to help your idea or invention get dialed into the proper power zone. You must do this within 30 days of purchase and the coil you trade in must be in working condition.
There is a $99.00 repair, installation and testing fee in the "Oops program"
(Much cheaper than buying a new PMA)
The purchaser is responsible for ALL shipping fees. If you are the lower 48 states the $99.00 fee covers return shipping. Email us for more info on the "Oops program". We are here to serve your needs and picking the right PMA the first time can be very hard with so many unknown variables in any power equation.

SC Series Friction Roller Note: The SC series PMA's are so powerful we do not normally recommend them for low RPM/High amperage systems. Design your system to make most of your amperage at high RPM's so your friction roller does not slip and lose wheel contact.
