Optimized for 48 volt battery charging at  speeds from 300 to 1500 RPM

This DC model INCLUDES three phase rectifier.  This high voltage model

can transmit power over 300 feet with low line loss.

550 watts peak- 45/195 volts peak in extreme wind gusts (Make sure your equipment can handle these peaks)   Designed to operate in an area with low/medium speed averages of 4.4 to 5.6 m/s and greater (Zone 2-4)   Provides 91 kWh per month ( 1186 kWh year)  3.25 kWh per day in a 12.5 mph (5.5 m/s) average wind speed.  In a zone 7 area this turbine can make up to 200% more power or 6.5 kWh.

Wind Zones are defined by m/s

Wind Zone 1      0 – 4.4 m/s

195V    48V  (for 48 volt model)

FOR USE ON WIND TURBINES ONLY!!!  NOT FOR USE ON ENGINES OR HYDRO.  PLEASE CONTACT US IF YOU NEED A PMA FOR ENGINE OR HYDRO USE AS THEY ARE VERY DIFFERENT TO WIND PMA TYPES LIKE THIS MODEL.

We sell really great wind turbines too: LINK HERE 



Includes a real original  
SLANT-CORE PMA - 

There are plenty of "Look-A-Like" PMA's on the market that cost less.  

The modern type PLATE AND GROOVE rotor that we have developed is the most celebrated and also the most copied type which we pioneered.  The important part is that PLATE AND GROOVE makes power at MUCH LOWER RPM's than the older and traditional Clam type rotor designs that do not provide deep magnetic saturation of the Stator coil offering 600% more power in low RPM scenarios over Clam type designs

In small wind turbines this is VERY important to make your power in the LOWER RPM ranges.

Spend a little more and get a LOT more  BANG-FOR-YOUR-BUCK!!!  Money well spent!

From the beginning GM designed the Delco to run

WET and even tested them to operate Under Water!

Designing an alternator that can survive at 375 degrees F. under the hood of a car operating with rain water coming through the radiator and from water puddles is No Easy Task!  Over 100,000,000 10/12si's were produced by Delco and after-market vendors! Parts for this legendary 'work-horse' will be available for the next 50+ years.  World's most supported and well recognized model!

Our Magnets are on an angle 
We make our own brand new
ROTOR POLE SHOES AND STATOR CORES!!!
Our PMA's are built from the ground up using only 100% ALL new parts!
(Including the rotor pole shoes and stator coil stacks)
 
Our NEW rotor poles are balanced to within .002 grams for SMOOOOOTH rotation!
 
MADE IN THE USA!

Use these powerful permanent magnet alternators (PMA's) to make cheap electricity with wind turbines 

Stop wasting up to 50% of your power energizing the coil of standard brush type alternators. Get a real PMA!

Permanent magnet alternators are by no means standard "Automotive" alternators containing brushes and electro-magnetic coils. A PMA does not waste power by having to continuously create an energy intensive magnetic field.
  We sell only highly efficient - long lasting true permanent magnet alternators!
 
"The SCS series PMA' are the most versatile
PMA's we have ever built"
 

  • LOTS OF LOW END POWER GENERATION ABILITY!!!!
  • Perfect for building simple, inexpensive and dependable wind turbines.
  • A put-up and forget design! Expect decades of dependable service life.
  • Bi-rotational. Makes power when turned in either direction.
  • Note: Clockwise is the preferred direction since the nut tends to stay on and it cools better!
  • All weather rated. Rain, ice and weather proof electronics.

  • 17MM hardened shaft.
  • Heavy Duty coils and diodes.
  • Light weight aluminum body.
  • Bearings rated for 115,000 hours +
  • 100% biassed magnetic field spread.
  • D.C. output. Includes built in rectifier.
  • Powerful #42H Neodymium magnets in rotor.
  • 7 magnets and 7 slave poles (Bi -poles) for 14 poles!
SCS series PMA's weigh 12 LBS. - Size 8" X 7" X 7"
WARNING!! Make sure you connect a PMA 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:
  
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. NOTE: If the shaft is scored-up badly you may have to sand the shaft down to it's original 17mm size to get the front housing off.
 
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 of the stator and this is unrepairable! 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 now unfasten the three wire nuts to safely remove the stator coil. (To reassemble simply reverse procedure)
 
Warranties will be void on any PMA that is opened by a customer.
Any PMA experimentation and examination is at your own risk.

Notes From Happy Customers

I just want to brag about your blades and PMA, I live here on a mountain
top in Idaho, and had freezing temps. Then came the high winds, the 12 volt
PMA maxed out over 75 volts and the blades held together with wind gusts
over 50 MPH. What a great product. I just need a controller that won't
smoke with these high wind surges, what do you recommend?
Thanks Sonny

You guys are great. By the way I'm very impressed with the scs24 pma
it seems to be out preforming the power curve in the ebay ad by quite a bit.

Thanks again, Brian
