Wind Generators

At INDAR the validation of the machines before delivery is compulsory in order to provide our clients with a reliable product. INDAR has the cutting-edge technology on this sector, including an electrical machines laboratory and test bench, which together with a highly qualified RDI department help us develop our products with in-house technology and adapt them to the customers' needs.

All information generated during the series and type tests is centralised and managed by an IT system which collects the parameters studied during the tests so that real instant readings can be obtained on the functioning of the machines. This makes it possible to gain a detailed understanding of the machine and its behaviour in all conditions, previously established depending on the working specifications and conditions required by the client.

The results obtained during tests are the basis of a process of optimisation, validation and adaptation of INDAR products to different applications and working conditions.

The validation of our custom-made designs and standard series is systematised in INDAR's test bench, with the capacity to carry out different tests on different machines simultaneously.
