150kva diesel generator,150kva diesel generator engine set for sale

Enercon pioneered a series of gearless direct drive wind turbine with a rated power output is now up to 4.5MW. In this design, the rotor is mounted directly on the generator, it can reduce the drive train bearing the number to only two low-speed rotating components. The question is how to generate enough power at low speed, and how the best way to convert it to the grid frequency. Methods Enercon company to solve the problem is to use a generator there are a large number of electrodes are electrically excited synchronous generator, for example, the company's E-40 models 600kW wind turbine generator in a diameter of 84 electric 4.8m pole synchronous generator excitation. Here, the rotor speed ranging from 18rpm ~ 34 rpm, swept area of ​​1521m2. Since the industrial design variable frequency drive strong foundation, Enercon company uses its own electronic circuits. In contrast, Zephyros company has just launched the Z72 type 2MW wind turbines while also having a direct drive generator, but the use of ABB's ACS 1000 variable speed motor drive improved controller. A drive shaft bearing is manufactured by ABB's permanent magnet generator. Zyphyros company include the generator loss reduction, excellent part load efficiency, the lower the probability of failure, etc., the highlight of the benefits of a permanent magnet generator. Inadequacies of permanent magnet generators is its use of high permeability magnetic material (such as neodymium iron boron and samarium cobalt) and costly. Another drawback of the permanent magnet generator is poor power factor characteristics, must be compensated by the frequency conversion circuit.20kw diesel generator set for sale 30kw diesel generator set for sale 50kw diesel generator set for sale 60kw diesel generator set for sale 75kw diesel generator set for sale 80kw diesel generator set for sale 90kw diesel generator set for sale 100kw diesel generator set for sale 120kw diesel generator set for sale 150kw diesel generator set for sale 160kw diesel generator set for sale 200kw diesel generator set for sale 250kw diesel generator set for sale 300kw diesel generator set for sale 350kw diesel generator set for sale 400kw diesel generator set for sale 500kw diesel generator set for sale 600kw diesel generator set for sale 800kw diesel generator set for sale 1000kw diesel generator set for sale 1200kw diesel generator set for sale1500kw diesel generator set for sale 2000kw diesel generator set for sale
