Leroy Somer

Leroy Somer- part of Nidec Industrial automation is a French company established in 1919. It is now the world specialist in industrial alternators and drive systems. With offices around the world they have designed their operations to be much more de-centralised to provide a swift response to the various markets.

Leroy Somer alternators can be categorised into two main segments -Industrial range, Low & medium Voltage, 4 & 6 pole, 50 & 60Hz, from 5 kW to 3.6 MW and the Customized (design to order) range, Low, Medium and High Voltage, 4 to 24 pole, 50 or 60hz, from 5 MW to 25 MW. While the Industrial range is designed for usage in gensets driven by diesel/ gas engines, Customized range are usually used in power plants.
