Highly Efficient Mechatronic Modules with Synchronous Reluctance Drives for Metallurgical Objects

The article discusses approaches to the synthesis of highly efficient electric drives with synchronous reluctance independent excitation machines. For this, an analysis of existing development methods has been performed. These methods are adapted for the developed systems. Unified approaches to the development of new types of electric drives with a synchronous reluctance independent excitation machine are proposed, which consist of a combination of traditional methods for selecting the power part of the electric drive and frequency synthesis methods. It is shown that in electric drives with a synchronous reluctance independent excitation machine, due to the independent excitation vectors and the armature, it is possible to significantly expand the band of uniform frequency transmission while reducing electrical losses in the system. Loss reduction in systems with synchronous reluctance machine is achieved due to the absence of losses in the rotor of an electric machine.
