The Hybird Drive Permanent Magnet Motor's Design And Dynamic Analysis

The new energy is a modern high-tech evolved since the 20th century, It has had a tremendous impact on the world's energy power industry restructuring, so we can see the vigorous development of wind power has an important significance. In this paper, a new type of power system using hybrid drive planetary gear characteristics, can reduce the cost of the inverter system, including the permanent magnet placed on the outer ring gear, electronic components instead of mechanical components for phase change to improve the system reliability.The main contents of the thesis are as follows:Use Solid Works'powerful 3D solid modeling function to achieve a complete model construction, especially the rotor system (here refers to the differential planetary gear train) structure design calculation. Based on power flow theory, calculating and analyzing the hybrid-driven performance;Under the principle of transforming the magnetic filed into a magnetic circuit do the electromagnetic design of the motor, and then analyze its operational characteristics; As the energy within the system is not a single form of analysis of multiple forms of energy, using power bond graph theory to analyze the system; Establish the bond graph model of the rotor system and dc generator, obtain the system state equation from the bond graph model, and use MATLAB/SIMULINK to simulate the characteristics of the system, analyze the simulation results. Changes parameters in bond graph model, and analyze the impacts on system performance because of the main parameters changing.
