It is VERY important to remember this when comparing to other PMA's containing standard automotive wire that is incapable of making high voltages!   Offered to you in naked unpainted metal so you know that you are only getting a brand new, never used PMA!   Including the pole shoes and stator coil frame!   We make our own brand new ROTOR POLE SHOES AND STATOR CORES!!!   The last company making new rotor pole shoes for the Delco 10 and 12si models stopped making them in 1998.   Most Stator coil frames are all USED and can be quickly recognized as used if they are painted. We punch out NEW stator coil frames daily so they fit like a glove offering maximum life and power. Used and painted stator coils can be generations old and could be OVER-CUT from continued rebuilding severely limiting their power outputs.   Ours are perfect, brand new coils and stator coil frame stacks with seamless laminations. Great workmanship!!!   Make sure your rotor is brand NEW and has also been re-balanced on adynamic rotor balancing machine or your PMA will NOT spin smoothly!!!   Our PMA's are NOT re-built units starting with junk yard alternator parts (Including the rotor pole shoes and stator coil stacks) 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!   PROUDLY MADE IN THE USA!   Slant-Core Design   ZERO COGGING Slant-Core PMA's have amazing power and GREAT low speed start up! Can be turned at speeds over 18,000 RPM   The #SCS12 can make 12 volts at only 275 RPM     By Hornet Power Systems               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!   #SCS series - Slant-Core PMA Technology!   Our "Slant-Core" PMA rotor is studded with powerful 42H Neodymium super magnets arranged in a superbly balanced and perfectly phase biassing configuration. This new design feature offers high power with no appreciable cogging.   All magnets are all slotted into multi-layered steel plates for maximizing and sharing the rear field forces boosting the overall core power.   When ordinary stator coils are hyper magnetically saturated with the Slant-Cores powerful magnetic field, power outputs are almost doubled over older mono core designs!   "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. Warranty - 90 days parts and labor FOB Lancaster, CA Powerful #42H Neodymium magnets in rotor. Nice and smooth turning for a PMA this powerful!   #SCS SERIES PMA ALL PMA's include only the spacers, shaft nut and lock washer.     #SCS12 - (Used for HT12SCS)     SCS series PMA's weigh 10 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!!!   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 WARNING; High voltage PMA's and battery banks can cause lethal electric shock! PLEASE NOTE: Our model numbers have nothing to do with voltages, they are just model numbers.   POWER CURVES NOTE: These Ratings are ONLY to be used as a basic guide line. Voltages are usually much higher than shown so expect more.     How readings are derived. Since we do not know the torque of the driver this data is given in absolute separate peaks and never as an absolute dyad reading. Amps are read as a short in the circuit closed condition. Then we read Volts in the circuit open condition. These charts do not reflect working conditions only the absolute PEAK separate readings. An engineer can then use this data and extrapolate actual power by adding in actual Horsepower V. RPM and the torque properties of the particular driver in the application that the PMA is to be used in. This is the unknown data only the engineer can provide. Simply dividing the peaks by 2 if not enough especially if the driver is weak and prone to lag under loads. Figuring this out is not for amateurs or beginners! The engineer can then decide on Voltage V. Amperage to be the dominant target factor based on individual necessity, current draw and the continuous available torque of the driver (source of rotation - engine, turbine etc.) PLEASE NOTE: VOLTAGES - ARE RATED WITH CIRCUIT OPEN - AMPERAGES - ARE RATED WITH CIRCUIT CLOSED- ACTUAL CHARGING VOLTAGES MAY VARY DEPENDING ON YOUR SPECIFIC LOAD. These curves shows the maximum Voltage OR Amperage POTENTIAL but is not showing both SIMULTANEOUSLY!!! Only YOUR specific LOAD can determine the final Wattage. 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.     CLICK DRAWING TO ENLARGE Used on 12 volt wind turbines!
