Abstract: In the application of the motor, the mathematical model of the permanent magnet synchronous motor can be in the d/q
model or ABC model is established. This paper in order to better achieve permanent magnet synchronous motor vector control in
permanent magnet synchronous motor voltage, current and magnetic chain based on the relational expression, using MATLAB estab-
lished the mathematical model of the simulation model, and combined with park and Clarke transform to the established mathematical
simulation model was verified. The simulation results show that the established permanent magnet synchronous motor of the validity of
the model. Thus for permanent magnet synchronous motor speed of provides more simplified model and the more a wide range of
applications.
