The applicability of the acoustic emission method for monitoring the motor winding reimpregnation is proved. The dip infiltration technique is described. An acoustic emission monitoring model for the motor winding reimpregnation through the impregnation method by example of a plaster prototype is offered. Two project scenarios of bubbling and corresponding mathematical models are presented. In the first instance, bubbles entering the liquid collapse, as they are affected by the liquid hydrostatic load and surface tension forces. In the latter case, bubbles caused by the buoyancy force come to the top and collapse being affected by the intrinsic pressure. The acoustic emission impregnation control provides process quality improvement, precise determination of the process time. Thus, the residence time in the toxic area can be shortened, the shop hazard rating can be lowered (and consequently, costs of employee compensations and benefits can be optimized).
