    Description

    This is a new Hydro Generator for use in Water Generation Projects designed by Motenergy, Inc.  The Generator is rated over 1000 watts at 480 VAC.  Easy to install and adjust to maximum power with the Adjustable Spear Valve Nozzle.
    The Generator has a stainless steel shaft and Aluminum Adapter Hub to fit the Turgo Wheel.  The Turgo Wheel is made from Polycarbonate Plastic for long life.   The output is 3-phase, Y-connected AC, and it can be converted to DC with the use of a 3-phase Bridge Rectifier (Rectifier is not supplied but can be found on eBay for ).  It has a 7/8 Inch diameter shaft with a 3/16" keyway.
    The Spear Valve is adjustable.  It has an input with a 1 - 1/2 Inch (1.5 Inch) G thread BSPP.
    The output is set for over 2.5 amps AC per phase, which means you can get 4 amps DC from a 3-phase bridge rectifier.  This is a continuous 4 Amps DC, 24 hours per day, 7 days per week.  There are two windings on the alternator.  The first winding (main winding) is 3-phase (A-B-C), and there is a second single phase winding (D-D) good for 10 amps at 1/10th the voltage of the main winding.  The second winding has 1/10th the turns and 1/10th the output voltage of the main winding. It is labeled D-D in the drawing below, and good for about 100 watts to run 12 VDC lamps or indicator lights.  Most people do not use this secondary winding.
    This is a 12 magnet, 12 pole, (6 pole pair) rotor, so the output frequency is calculated as Speed in RPM/60 * 6.
    Note that the voltage output is proportional to the speed of the generator.  As you spin faster, the voltage increases.  Also note that this unit will not run appliances directly.  It does not provide 120 VAC, at 60 Hz, single phase power, nor does it provide 240 VAC, 50 Hz, single phase power.  If you need this type output for single phase then you need to purchase and add your own Inverter.  The SunnyBoy 3300 works well with these generators if you add a 3-phase full wave bridge rectifier to the generators output between the inverter and generator.
    Most Hydro and wind systems also need a Dump Load and Charge Controller.  We recommend the products at www.Colemanair.us, which are also sold on Ebay.
    The generator has very little cogging torque which means it will provide power with very little water pressure.  The magnets are Ceramic and can run at very high temperatures, unlike Neodynium magnets that are only rated for 300-350 F.  This is an air-cooled generator.  It is an outer Rotor design, and the Rotor will be spinning on top of the Generator.  A cover or guard should be placed over this unit to protect a user from personal injury if you touch the spinning wheel, and also to protect the unit from the outside environment.
    There is a water seal on the shaft, and the mounting face has plenty of area to put a gasket or RTV sealant.  Note that this is an Outer-Rotor design.  The shaft and outer-rotor spin, and the center stator (coils) remains stationary.  The generator diameter is 204 mm (about 8 inches).  It can be mounted with 4 bolts, 5/16-18 on a 3.75 inch bolt circle. (Bolts not included)
    The Turgo Wheel is part of this Auction, and it is in the box with the generator.
    For international buyers, you may have to pay some VAT or Duty when the goods arrive in your country.  We ship by United States Postal Service, which states 6-10 days delivery to international locations, but it can take longer due to the Customs Clearance in your country.
    For reference, here is a quick calculation for an approximation of the available power at your site:
    Flow in GPM x Height in Feet x 0.09 = Output Power in Watts         (GPM is Gallons Per Minute)
    Flow in LPS x Height in Meters x 4.45 = Output Power in Watts       (LPS is Liters Per Second)
    Also note that we do not recommend these generators for Over Unity and Perpetual Motion machines.  These generators are 85% to 90% efficient, which means that up to 15% of the energy input is turned into heat in the windings, plus windage in the fan, and it used to overcome friction in the bearings.  You will not get more power out of this generator than what you put in.  We do not recommend that you try to use the generator's output to run a an electric motor, that is connected to the same generator.
    Some assembly is required.  The Blue Base Box has pre-drilled holes for the generator and nozzle.
    Please ask questions before you purchase.
