Design of Modular High-Speed Copper Coated Solid Rotor Induction Machine

This paper presents the concept of a modular high-speed solid rotor induction machine. The utilization of this type of machine is mainly for the verification of the solid rotor manufacturing technology, where it is necessary to verify whether the rotor can withstand centrifugal forces at nominal speed. Due to the very simple construction of the machine, enclosed in a frame that can be easily assembled and disassembled, the rotor can be replaced very easily. Therefore, it is not necessary to create a prototype for another machine but to verify the technology for the production of the solid rotor. In this case, copper coated solid rotor technology is used. The concept and dimensions of the machine are also presented here, including the calculated electromagnetic parameters and rotor dynamics of the machine, using numerical methods. The advantage of utilizing the machine is in the reduction of the cost of producing different machines.
