This leads to major advantajes, as the external power source for the rotor and the brushes are eliminated, minimizing the auxiliary systems required for operation and eliminating all losses related to the excitation system.

Furthermore, through proper desing it is possible to achieve direct drive configurations, where the generator and the blades are directly coupled, eliminating the need for gearbox to adapt th speed of both components.

Our technical department has extensive experience on designing high quality machines between kW, using cutting imanes permanentes design and manufacturing tools and techniques. This is the guarantee to achivering profitable solution, with high quality standards and customer satisfaction.

During the design and manufacturing process we select and use the most suitable materials for each one of the components. Sintered Al-Ni-Co magnets production starts with the preparation of the starting material by mixing raw materials either in pure form or in compounds, imanes permanentes the aim of obtaining the desired composition.

Afterwards, mixing is required to ensure homogeneity within the material.

Pressing to the desired shape can be done using a imanes permanentes of techniques, although isostatic pressing, either cold or hot, is preferred Dillon, ; Tang et al.
