low rpm permanent magnet alternator for sale/mini hydro generator

Product Description

Engelec supply variety of permaent magent generators which is suitable for driven by following equipment to

1. Driven by Wind Power ----Wind turbine
2. Driven by Water Power ---- Hydro generator
3. Driven by Belt with Motors
4. Driven by Motor
5. Dirven by perpetual motion machine
6. Dirven by test plant
7. Dirven by yourselves creation
8. Driven the permanent magnet generator and make it rotate then it can generate power

We are manufacturer of hydro power generator, PMG permanent magnet generator, NdFeB permanent magnet generator for hydro power system.

Features:

1.Low speed permanent magnet direct-drive water power PM generator. Break the limits that excitation generators can only work at high speed and at constant speed. The PMG can work at low speed, variable speed situation, very suitable for low water head generation or river power generation, seasonal water power generation.
2.The PMG has many poles. Do not need the gearbox. The PMG can output 50Hz at low speed. The PMG can be tied to the grid directly or via an on-grid inverter.
3.The power plant power can be designed according to the wet season water amount. Then the power plant can use all the water flow in the wet season. The power plant will get more power in the wet season, and get small power in the dry season. The total generation amount can be improved by 100%.
4.High efficient permanent magnet rotors. No brushes, no sparks. No excitation, no excitation windings. High strength rotor, simplified structure, high reliability.
5.The PMG are high efficient throughout the whole speed range, saving energy. The efficiency is improved 20%, compared with the excitation generator.
6.Protection class: IP54,avoid water, mud, dusty getting into the motor, long life, especially suitable for outdoor requirements.
7.The PMG can be wind cooled or water cooled. The bearings are imported oil-contained bearings, maintenance free, high reliability, long lifes.
8.You can change the motor voltage, speed, Power and other parameters, the out size of the motor can be also changed. You can use splined shaft, dual shaft, flange and other output styles. Our main exporting countries:USA, France, Canada, Australia, Norway, Germany, Denmark, Italy, Spain, UK, Latvia, Romania, Korea, Iran, India, Pakistan, Thailand, Malaysia, Mauritius, Kenya, Brazil.
