The initial investment and operating cost for the 25-30 lifetime-years of the transformer will be called Total Cost of Ownership. Within the Operating Cost of the device is included the cost of the dissipated electric energy at the windings (Cu) and at the core (Fe). Consequently, had the core losses been diminished (by using amorphous metal cores), the Total Cost of Ownership of a device produced by this technology would be reduced in comparison to those produced by traditional technology; and would profit a considerable economic gain to the owner of this machine. From this point of view, the implementation of an accurate winding system as the one proposed, presents an optimum solution to the formerly described process, not only to behoove the handling of the final product, but also to simplify the post-melt spinning heat treatments, such as isotermic annealing which is used to obtain nano-crystalized ribbons (Muraca . et al. 2009).

crucial to prevent unwanted flaws (Saito, 2010; Marashi et al 2009) which include the absence of the formation of the strip on the casting wheel as can be seen in Figure 11. For this reason it is highly recommended to ensure the working conditions described along this article.
