Renewable energyOur power generation equipment for distributed generation have undergone system upgrades that enable them to easily and efficiently configure clean power generation systems that use wind power, smallscale hydroelectric power, biomass, and other renewable energies through the use of state-of-the-art equipment.


Small-sized permanent magnet synchronous generator Approximately half the weight of an induction generator

Compared to the average induction generator, our equipment delivers the same output with a lower center height and a dramatically lighter motor weight.
(About 32% to 57% lighter than the average induction generator.)

High efficiency

Using our permanent magnet synchronous generators (EDG), along with a converter for high-efficiency control, enables 94% total efficiency from the generator to the end of the power line when using a high-capacity model and 90% efficiency when using a low-capacity model.

Clean power

Stable voltage and frequency is delivered at the point of grid connection, even when the generator (drive unit) changes rotating speed, and the sine wave output current contains almost no harmonics.
