Abstract：In order to reduce cost, risk and development time, the real-time simulator of electric vehicle system can be used
for concurrent engineering. An implementation of the real-time model of brushless DC motor drive for the electric vehicle
based on block-oriented programming tool Simulink is proposed. Also, by using dSPACE environment，the real-time code
of controller and inverter-motor-sensor model is directly generated. Having the real-time hardware interface to actual
system, the real-time simulation system can be directly connected to actual controller or real inverter-motor-sensor system
for hardware-in-the-loop simulation test as well as for rapid control prototyping applications. Experimental results show
that there is no remarkable difference between the responses of the real system and the real-time model, so the real-time
simulation system can replace the real system in the development and test stages.
