Missouri Wind and Solar FREEDOM 3 Sealed PMG
(permanent magnet generator)

 

 

New for 2019: Fully Sealed PMG Designed for Wind Turbines and Hydroelectric Power

Great for Marine Environments!
For Use On Land or Sea


The NEW Missouri Wind and Solar PMG is fully sealed to create a water-resistant motor for wind and hydropower. Truly well thought out with years of R&D behind the production. 

Some of the features include:

  • Larger bearing to withstand wear and abuse

  • Sealed front bearing with additional labyrinth style seal

  • Case with a rough, natural finish which means more surface area to speed cooling and improve output performance

  • Keyed shaft and hub stabilizer that bolts on to the blade hub to prevent slipping and improve safety

  • Hub stabilizer that channels water away from entering through the front of the housing

  • Gasket style seal to keep water from seeping into the case

  • Water resistant design - no marine varnish or painting required

  • Wind tunnel testing up to 55 MPH


We've had the motor installed at our store in Seymour, Missouri with great results and have even run it through our wind tunnel test at 55 MPH. The fully sealed motor is perfect for marine environments but can be used anywhere a wind turbine can be mounted.

Just like the Missouri Wind and Solar Freedom PMGs, the Sealed PMG contains more copper than typical PMAs on the market. What does that mean? More copper equals more power output! Our custom made skewed stator reduces cogging and allows startup in lower wind speeds.

Why are Missouri Wind and Solar Freedom PMGs Better Than Others On The Market?

  • Most PMAs use a thin aluminum housing and the stator is not pressed in. The MWandS Freedom PMGs feature a very thick aluminum housing and a pressed in stator that helps with proper alignment, durability, and cooling.
  • PMAs have only two mounting holes. MWandS Freedom PMGs have four of mounting holes bolted tightly against the mounting bracket for secure mounting.
  • Alternators and some PMAs have a weak rear bearing. The MWandS Freedom 3 Sealed PMG utilizes large sealed bearings to stand up to wear.
  • Most car alternators and PMAs that are re-purposed use low grade/high iron electrical steel and aluminum windings which can create a lot of heat. The MWandS Freedom PMGs use high-grade electrical steel, real copper winding, and is optimized for efficient cooling.


Freedom 3 Sealed PMG Specifications:

  • 17 mm stainless steel shaft compatible with all Missouri Wind and Solar hubs and blade sets
  • Custom hub spacer/stabilizer with keyway and bolts for attaching to Missouri Wind and Solar blade hubs
  • Zinc plated 14 rare earth neodymium magnet rotor
  • No brushes to fail or replace
  • Large, heavy-duty bearings in front and back
  • Fits delco bolt patterns and mounts up to our standard mounting bracket
  • 3/8" Diameter bolt holes
  • 1 15/16" on center between mounting holes
  • 5 7/8" OD Width
  • 6 5/16" Tall
  • 10 pounds

Warnings:

PMA and PMG cases should not be painted or coated - this prevents heat from leaving the motor and reduces efficiency. If you have an open-faced motor like our Freedom single and dual PMGs, you can marine varnish the interior components.


The Freedom 3 sealed PMG should not be run at over 240 watts continuously in a gas or electric belt-driven application without proper cooling fans. Running the motor continuously without air moving across the case may result in overheating.
