PMA Generator ME1112 Pelton Wheel Water Power 0-240 VAC 4000 Watt Micro Hydro

Description: This is a new Permanent Magnet Generator for use in Water Generation Projects designed by Motenergy, Inc. It is rated at 2000 watts at 1400 rpm, and up to 4000 watts at 2800 rpm. Motenergy Part Number ME1112. Comes with a Pelton Wheel. Part Number ME0903. The product has a stainless steel shaft that is designed to fit the Motenergy ME0903 Pelton Wheel. The output is 3-phase, Y-connected AC, and it can be converted to DC with the use of a 3-phase Bridge Rectifier. It has a 7/8 Inch diameter shaft with a 3/16" key way. The output is set for over 11.5 amps AC per phase, which means you can get 16.3 amps DC from a 3-phase bridge rectifier. This is a continuous 16 Amps DC, 24 hours per day, 7 days per week. There are two windings on the alternator. The main 3-phase winding (A-B-C), and a second single phase winding (D-D) good for 10 amps. 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. The 3-phase voltage (A-B-C) is set to provide 12 VAC at 140 rpm and 200 watts, 120 VAC at 1400 rpm and 2000 watts. At 2800 rpm, you will get 240 VAC and 4000 watts. The fan works best when the generator is run in the Clockwise direction, looking at the shaft. 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, 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. It 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. 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 Pelton 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 0.18 x 0.5 = Output Power 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, windage in the fan, and 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.
