With the engineering expertise and deep technical knowledge, we work towards designing & manufacturing reliable, innovative solutions for transmission, control and power generation in the renewable energy & industrial sectors.

Our products find applications in wind technologies, hydro-turbines, and industrial machines etc. We always work to innovate products that solve the problems of power efficiency as well as keep our environment clean & green. We offer economical and technologically good solutions to serve the industrial and commercial sector markets. We make effective use of the components and technologies to manufacture quality products. 

What is a Permanent Magnet Generator?
 
A permanent magnet generator converts the mechanical energy into electrical energy. This device uses permanent magnets instead of the rotor windings. It does not require a separated DC supply for the excitation circuit, or has contact brushes and slip rings. These devices are excellent alternatives to traditional induction motors, and can be linked with diesel generators, turbines & hybrid vehicles. Also, these machines do not require a specific work environment and thus can be utilized in wind, water machines.

The Permanent Magnet Generator (PMG) can work as a DC voltage machine with rotary collector, brushes, or more often an AC synchronous multiphase device whereas the rotor and stator magnetic fields are turning at the same speed. This ensures reduced excitation losses in the rotor, represent 20-30% of the overall generator losses. The decreased losses also help in lower temperature rise in the generator. Hence we get a more cooler system, offering improved reliability and life of the bearings.

A small piece of Neodymium Boron Iron (NeFeB) is ten times stronger than the conventional ones, and we keep up with the same effective material. With further research we can also improve the reliability & strength of the PMG. The demand for this device is increasing day-by-day. Also, the machines do not use environmental resources to make energy, and are environment friendly. They can reduce the pollution impact by upto 50%, and environmental experts suggest the utilization of permanent magnet generators.
