SIMULATIONS
BIKE GENERATORS
|
This is a simulation that you can download and run on your Windows computer. Below is a screen shot of the simulation demonstrating currents and electromagnetic fields inside an the empty stator of an AC 3 phase motor. The animated image below is quite choppy because it had to be made small to fit on this web site. However, if you decide to download and install the simulation it will run quite smoothly and you will be able to change the impedance of the windings, and the input voltage. You are looking at the end view of an empty stator. You will have the option of clicking on a switch to see current flow in the coils. The red an green dots represent current flow. Red is into the screen, and green is out of the screen. Click on another switch to see the magnitude of the phase voltage represented by plus and minus signs. You also get the option of showing emf resultant for coil A, coil B, coil C, or all 3 combined. It's fun to try and play with the coil impedance to see if you can get the coil current out of phase with the supply voltage.
