Impact Study of Field-Weakening Operation of Electric Motors on Drive Train Oscillations Conference Paper uri icon

abstract

  • Studying the dynamics of electric motor drives is not easy. Indeed, there is no unified approach to model both the mechanical and the electrical elements of the motor drive in order to bring an intuitive understanding of the dynamic behavior. Moreover, for traction purposes, the machines are often used at field-weakening operation, which can be a source of unwanted oscillations. In this paper, the gyrator-based equivalent circuit modeling is presented. The method allows the understanding of some aspects of the dynamic behavior of DC motor drives such as the interaction between electric inductances and the rotor inertia and their oscillating behavior.
