<Abstrcat> With the wide use of brushless DC motor, it is important to build its simulation model. Some simulation models for a brushless DC motor have many disadvantages and inconveniences, but a simulation model based on a new object-oriented simulation software Dymola can overcome them. Dymola modeling and simulation for a brushless DC motor system are built on the base of its mathematical model. This simulation model makes it possible to proof varied control strategies and algorithms. It can also be used to analyse the steady state and dynamic state of brushless DC motor system.
