Have you looked at the free online LabVIEW tutorials?
Also, there is a control design and simulation tutorial:
Check those out...they should get you started.
First you said you want to simulate and induction motor starting. I don't know exactly what you want to simulate, is it modeling voltage, current, feedback loops, speed, torque of an induction motor? That is all calculations and has nothing to do with hardware.
Or do you want to actually start a real motor, which has nothing to do with simulating anything. If you want to start a motor, you will need a data acquisition card with a digital output or a relay output. With that you can drive another relay which can drive a motor starter relay.
No, because I really don't know what you are doing.
What are you simulating? So far, all you've wanted to do is how to "simulate" turning on a motor. A motor is either on or off. So you have a boolean value that would drive a digital output which would drive a motor contactor/starter if you had any of that hardware. Since you don't, all you can do is put a boolean indicator on your front panel.
Do you want to simulate inputs from these sensors as well? Then put some front panel controls that you can adjust which you can later replace with the signals coming from these sensors.
