Permanent Magnet Generators for Hydroelectric Applications


Our permanent magnet generators have been used in a wide variety of hydroelectric applications. From penstocks to tidal projects, the company’s generators have stood the test of time by providing reliability and affordability in an industry where it is vital. We currently provide permanent magnet alternators for up to 100 KW projects.

Hydropower supplied 6.4% of the world’s primary energy in 2007, equating to almost a fifth of global electricity production. However, most large sites that can be exploited economically have already been developed. Smaller sites are now sought and much of the global undeveloped potential exists with sites under 100 KW in size. One major disadvantage of smaller systems is, being mostly run-of-river, they often experience large seasonal variations in flow. This can be a serious challenge in parts of Africa for example where the river discharge during the wet season is significantly greater than that during the dry season, and this will be exacerbated by climate change. This can be managed by having a variable speed permanent magnet generator that is able to utilize varying water flows for generating electricity.

Tidal and Hydrokinetic Power

Tidal power seems to take a front seat in the growing search for power sources that will fuel the growing global power demand. Permanent magnet alternators are required for tidal power due to the high fluctuations in water levels and the velocities of water. PMGL looks to play a leading role in serving this market going forward by matching its products with those in need of the industry.

Advantages of Low RPM Hydro Permanent Magnet Generators

Traditional generators require 1800 revolutions per minute to generate power. How can low rpm generators help you in this case? What are the other advantages of Low RPM generators in terms of life, efficiency and reliability? Know this and more by clicking here. 

How Do Hydro Permanent Magnet Generators Work?

With electricity bills, more and more people are looking for an alternative sources of energy, permanent magnet generator fulfills the needs perfectly. What makes permanent magnet generators a superior alternative to induction motors? How durable are these generators and how can they achieve highest efficiency? Know this and more by clicking here.

Hydro Permanent Magnet Generators: Price vs RPM

Hydro permanent magnet generators are operated at different speeds. But price becomes a compensation factor when varying the speed of the alternator. Price of an alternator is inversely proportional to the speed. Decreasing speed will result in increasing the size of the alternator. Know this and more by clicking here.

Hydro Permanent Magnet Generators: Voltage vs RPM

Voltage generated is directly proportional to the speed of the prime mover. Increasing RPM and Increasing the load will have effect on voltage in a hydro permanent magnet generator. Hence a relation between these factors is essential for manufacturers. Know his and more by clicking here.

Gearboxes give way to Direct Driven Turbines & Hydro Permanent Magnet Generators 

Direct driven turbines are proving to be more reliable and efficient. This reduces the cost of productivity. They have been around for quite some time now but their huge size and cost was a problem. But modern technology has developed newer, lighter and affordable models which are used in hydro permanent magnet generators. Know this and more by clicking here.
