Algodoo

@Xray can you please help me scripting the motor? i want this to have two buttons with Star mode and DELTA, basically changing the torque from 2000 STAR to 50000 DELTA

Sure, just give me a day or two and when ready I'll upload a scene to Algobox with two buttons for selecting two different motor torques. The title of the scene will be "For zigor". You can download the scene and copy/paste the buttons into your own scene. Okay?

wow great, thanks so much

By the way, "Star" and "Delta" refer to how the motor is wired to a 3-phase electrical power circuit. They are not normally switched. The star wiring configuration is the most common method, and the delta configuration is mostly used where high starting torque is required. Torque can certainly be selected via pushbutton switches, and so I will label them "Torque". One will show 2000 and the other will show 50000. When you download the scene, you can of course change the labels to whatever you want them to be.

yes but some 3 phase motors use two options for startup one is star mode wich starts slower and then the motor switches to delta for final kick

i dont think im totally correct...

I'm not an expert but I'm fairly certain it doesn't work as you described. Star (also known a WYE because it resembles the letter Y on a diagram) and Delta (it resembles a triangle shape which is the Greek letter Delta) are two different kinds of wiring. When someone purchases a 3-phase industrial motor they must specify if it will be wired in a WYE or a DELTA electrical transformer. To my knowledge there's no such thing as a motor that can be switched between the two configurations. I could be wrong, but I don't think I am. But for the purpose of your scene it really doesn't matter because you are only concerned about the torque which can be selected with an electrical switch such as a push-button switch.

MORE INFO: You can buy an industrial 3-phase motor that has three separate windings which can be connected to either a WYE or DELTA electrical circuit. But there's no reason for being able to switch between the two electrical configurations. Once the motor is wired to the electric power supply there's no reason to change the configuration on the fly. It is either connected to WHY or DELTA power circuit, never both.

oh ok thanks for the info
