- #SCS series - Slant-Core+ PLUS PMA Technology!
-
- Our "Slant-Core+"
PMA rotor is studded with 7 powerful 42H Neodymium super magnets
- 7 more "SHARED POLES are arranged
in a superbly balanced and perfectly phase biassing
- configuration. This new design feature
offers 14 high power poles 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-Core-Plus
- 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!

- 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
- We offer the longest extended
warranty in the industry - 10 years!!!
- You can buy an extended contract
for a full 10 years!!!!!!!!
- Standard warranty is 90 days
for all wind turbines on this site.

- 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
than 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.
- Torque Calculations:
 We have no Torque figures
since Torque is totally a function of LOAD. A PMA with no
- load requires ZERO torque to turn at
a ZERO load. You can't rate PMA's with simple torque
- figures since "AMPS" or "LOAD"
is up to every individual situation and individual people
- have endless configuration ideas for
their DRIVER and LOAD figures for whatever "Gizmo"
- they are building. A young healthy
human can generate about 300 Watts tops,, for a while.
-
- These is all you really need to know
is:
- 1 HP = 745 Watts / This is the conversion
figure of electrical power to mechanical power and vis-versa.
From the HP and YOUR amp load figure you can calculate any required
TORQUE figures for YOUR specific driver and YOUR specific LOAD
which WE do not know
- NOTICE FOR ANY OF YOU
A.E. NOVICES OUT THERE:
-
- 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!
-
- 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.

- Includes a LARGE extra 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 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. We 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.
-
- A PMA RUNNING SLOW WHILE DRAWING
A FULL AMP LOAD IS A DEAD PMA!
- Here is guide to help you choose
the right PMA and keep it cool via the correct RPM V. AMPS coefficient
- These figures must then be matched
to the power curves. This total calculation must be done
- correctly or you may find yourself
burning up a few PMA's as part of your learning curve.
- (Expensive lessons for the inexperienced!!!!!!!!
All Sales Final.)

/ AMP LOADS
- 0 to 999 Watts - No cooling fan required
= 0 to 999 rpm +
- 1000 to 1999 Watts - Required RPM for
proper cooling fan operation = 2699 rpm + (No cooling fan
required on wind turbines)
- 2000 to 2699 Watts - Required RPM for
proper cooling fan operation = 3999 rpm +(No cooling fan required
on wind turbines)
- 2700 to 3999 Watts - Required RPM for
proper cooling fan operation = 6999 rpm MIN!!! (No
cooling fan required on wind turbines)
- 4000 to 5299 Watts - Required RPM for
proper cooling fan operation = 9299 rpm MIN!!! (Cooling
