Dynamic response analysis of Permanent Magnet Brushless DC Motor drives for city electric car based on Matlab/Simulink

摘要

Electric cars becomes one of interesting object for researchers since its ability to meet the requirements of environmentally friendly vehicles. The driving force of electric car comes only from electric motor, hence the car performance is mostly determined by its motor dynamic response. This paper presents the modeling of PMBLDCM (Permanent Magnet Brushless DC Motor) with the load characteristics of an urban city electric car. The dynamic responses of torque and speed of the motor in constant torque region is discussed Tests carried out using Matlab/Simulink in an attempt to obtain data describing the dynamic responses of the motors driving city electric car.
