Abstract
The new wireless rotor electrical machine has all the coils placed on the stator. The laminated wireless rotor serves as a magnetic field switcher. A wireless rotor is cold, and it facilitates machine cooling. The model of the wireless rotor machine includes electrical and mechanical components. The wireless rotor machines can find an application in practice because they have advantages over existing devices. In modeling, we use a new approach. We consider a motor as a natural control system with torque feedback. Such an approach simplifies analyses and adjustment of the operation of an electrical machine. First, we analyze an open-loop control system without torque feedback. In this case, by changing the rotor speed under external torque, we can receive the torque-speed motor characteristics. After some adjustments to the open-loop system, we can consider the close loop control system with torque feedback.
We use a space vector representation for sinusoidal electric components. Such a description allows the use of sinusoidal components in transient conditions. For modeling, we use the graphical programming language, Simulink. The Graphical language allows showing the physical interpretation of the operation of a wireless rotor machine. The transient and steady-state results of modeling electrical and mechanical components are natural and visible at any point in the Simulink model. It facilitates the analysis results of the simulation. This modeling will find applications for designing the static and dynamic properties of the wireless rotor machines. The results can be useful for analyses and create regular AC machines.
