| Abstract: | A self-made maglev transportation demonstration model is introduced in detail.Basing on permanent magnetic technology,the model uses linear brushless DC motor to supply drive power,uses self-control inverter to ensure the synchronization of the frequency of the linear brushless DC motor's input electric current with the rotational velocity of the motor,and uses open loop control circuit to control linear brushless DC motor.The model works very well for demonstration. |
