overview

Whether it is a new infrastructure project or a revamping of existing ones, our generators are designed and made to measure to meet specific plant requirements.

GENERATORS FOR HYDRO APPLICATIONS

Generators for hydro applications represents one of the key area of expertise of our Motortecnica factory in S.Cipriano Picentino (Italy). Our company has specific skills for the complete design and manufacturing of generators for hydro power plants. We also carry out the repair, service & maintenance of large hydro generators worldwide.
With strong references in the field of diagnostics, maintenance, repair of electric machines, both in our workshop and onsite, we are the right partner to refurbish your machine.

DIRECT DRIVE PERMANENT MAGNET GENERATORS

Nidec Industrial Solutions supplies direct drive permanent magnet generator solutions allowing the hydro plant to operate under varying conditions of flow and/or head over a range of values that are unattainable with a traditional fixed speed system maximizing turbine productivity.
The permanent magnet generator can be directly coupled to the turbine, eliminating the need for a gearbox. The significant absence of rotor losses and the design flexibility associated with the use of sintered magnets allow us to manufacture high polarity machines that are compact and efficient. These generators are easier to control and more reliable than traditional induction and synchronous generators because they do not require any intermediate transmission devices and excitation systems. The rotation speed is coordinated in real time by several system parameters according to the available flow and/or head.
