Concept and Main Results of Development of Induction Motors with Removable Cores
摘要
The algorithm and main results of the development of a line of electric motors of modular design are presented. The technology of stator core production involves separate production of the frame and the wound stator core with their subsequent assembly. The design elements of the motors of the line (frames, bearing shields, cooling modules, terminal boxes, etc.) are unified with the possibility of their combination for motors of several sizes. When designing the active part, the concept of maximum unification of technological equipment was adopted. Considerable attention is paid to increasing the efficiency by reducing additional losses. The design algorithm is based on the combined use of mathematical models based on circuit theory and models based on the finite element method.
