- Abstract
This paper presents a new way to increase efficiency in motors with semi-closed slots by casting the slots with ferro-resin instead of using permanent magnetic wedges. This way of increasing efficiency is particularly important for high-efficiency motors. Field calculations (FEM) and laboratory tests of the motor before and after casting the slots with ferro-resin were performed. Optimization calculations were carried out to estimate the reduction in the use of active materials in a motor with ferro-resin casted slots. Based on the results of laboratory tests and calculations, the advantages and disadvantages of using the new method are presented.
