  Machines with permanent magnet excitation have higher efficiency and more reliability than machines with electric excitation. Among the permanent magnet machines, the crossover machines have a higher ratio of power to volume and electric torque to volume, so that at the same power, their size is smaller than the usual permanent magnet machines. And this is the reason why researchers have paid attention to crossover machines in recent years. Cross-phase generators can be made with a smaller pole pitch than other machines. These features make these machines have a higher power density than other permanent magnet machines. The copper winding of the crossover generators is simple, and their passive copper winding is considerably less than other machines, so the mass of active materials required to produce power and electric torque can be less than other machines. In other words, a smaller volume of active materials per unit of electric torque can be obtained by these machines. Therefore, this generator creates high power and torque by creating a large number of poles and a small pole pitch, and it can be a suitable option for use in the production of electrical energy from wind power, especially at low wind speeds.  The lack of a suitable dynamic model and the application of this generator, dynamic modeling and simulation, are necessary to analyze its performance under different conditions. Therefore, this article presents a dynamic model for this generator to be connected to the wind turbine, and then simulates the wind turbine based on this generator by simulating the turbine-generator system.
