A motor is used to simulate the wind turbine, and a variable frequency drive is used to simulate the wind velocities. Automation is achieved by magnetic bearings and are triggered when the ideal velocity of the wind (depicted by the RPM of shaft) is reached. Combination of 3 magnetic bearings is used for each shaft, the motor (wind turbine), the alternator/generator and the flywheel. System can be improved by minimising frictional forces.
