METHOD FOR POURING RESIN IN A STATOR OF AN ELECTRIC MACHINE, IN PARTICULAR AN AXIAL FLUX MACHINE

摘要

A method for pouring resin in a stator (2) of an electric machine, in particular an axial flux machine, in which a plurality of coils (5) is supported by a magnetic core (4) contained in a container (12), in which resin is poured in order to fill the spaces existing between the various components contained in the container (12). The method comprises the steps of heating a resin (20) until it reaches a pre-set temperature T1, corresponding to which is a target value of fluidity; supplying in a controlled way an electric current Istat to the coils (5) so that the current will flow in the coils (5), which behave as resistors, thus obtaining a heating by the Joule effect of the coils (5) which reach a temperature T2 that is higher than the temperature T1 of the resin; mixing the resin with a catalyst and pouring the mixture of resin and catalyst into the container (12) so that the resin fills said spaces; and obtaining complete hardening of the poured resin.
