ENGELEC
EN-250KW-375R-50Hz-380V
EN-250KW-375R-50Hz-380V AC Three Phase Permanent Magnet Generator
Overview
Low speed permanent magnet direct-drive generator. Do not need the gearbox. The turbine connects with the PMG directly, simplifying the structure and improving the system performance.
The gearbox reliability is not high. The system reliability can be improved if there is no gearbox. That means less maintenance, better utilization, longer lifespan for the system.
The efficiency is high. The system efficiency can be improved by 20% when you use PM generator without gearbox.
The PMG can work efficiently throughout the whole speed range. Less heat when working. The PMG can use natural air cooling.
Low start up torque, the system can output power at low speed.
The PMG works at low speed, low noise, more safe and reliable, the lifespan of the bearings can be longer.
The voltage, speed ,power of the generator can be customized. The shape can also be changed, using spine shaft, dual shaft, front edge or other output ways.
Application
EN-250KW-375R-50Hz-380V AC three phase permanent magnetic generator(PMG) provide best magnetic flux density with less air gap. It requires no system for the provision of field current. It is highly reliable. It contains any means for controlling the output voltage. Typically used for HAWT&VAWT wind turbine and hydro generator where the generator output of variable voltage and frequency is supplied to a power system through an electronic frequency converter.
Advantage
EN-250KW-375R-50Hz-380V with multi poles in PMG, improved the power efficiency at low speed and solved unstable output voltage problem, also saved the cost. They are widely used for direct-drive horizontal axis or vertical axis wind turbines.
The best efficiency of ENGELEC PMG is over 96%,
Reasonable structure and low starting torque, solved the difficult start-up problem at low speed
Brushless, no excitation winding and control box, simple structure, no sparks, high reliability.Imported high-speed bearing with oil-containing, which is maintenance-free, highly reliable and has long motor life.

A: Our PMG is very convenient and easy to install. We will offer the installation manual with the goods together, you can finish installtion within 3 minutes by following the manual.
A: We use cast iron for the generator shell and the core in cold rolled silicon steel sheet,. NdFeb magnet rotor is verty strong to support in high rotating speed. High efficiency, especially in the entire speed, save energy, reduce long-term operating costs, and save motor purchase cost by one and a half years of power saving.
Our PMG is free-maintainance. The whole device serive life is 20 years.
Two method in bearing, one is with cap, bearing life is about 5 years, just change it. Another one is no-cap bearing, add some lubricating grease half a year to make it working smooth.
