This thesis Presents the concept of the eddy current generated in the bar. Therefore, the author thought to the eddy current That can"t be macroscopic to show in the way of mechanical, Nik. For the sake of the eddy currentThis thesis The inverter AC 3 phase, using microcontroller dsPIC30f4011 จะมีโมดูล MCPWM 6 channel, can control the source signal. PWM model output can freely adjust the frequency since. 1-130Hz to control the use of simulation set the eddy current in the iron bars.The project dissertation To see the movement of small sticks up using a simulation model is to see the eddy current in the iron bar, and the use of inverter 3. Phase in which a power supply alternating current. Able to adjust the frequency from the frequency 1-20Hz when more will make the ball bearings have been moving faster. And the bearings will gradually slow down when there is a low frequency scaling down.
