Yes, that's possible, but only for low-powered motor. You know that in order to start, the stator must be supplied with voltages that are shows shift phase between them, so the trick is to use a capacitor (since it shifts phase current) to simulate a 3-phase source. As indicated in the following picture: http://freecircuitdiagram.com/wp-content/uploads/2010/10/Enabling-3-Phase-Motor-Operates-with-Single-Phase-Supply.gif
Depends on the motor. If it is a synchronous motor it will run too fast.
yes,
Only one neutral conductor is typically in a 3 phase panel.
It will probably run but not correctly. Low voltage will cause the motor to draw less amps than it's designed to. It will not reach its rated RPMs and such slow operation may shorten its operating life.
3 phase reverse relay can be utilized to control 480V motor 60HZ for controlling their speedspeed.
That's 277 volts of alternating current. This is typically one phase of a 480v 3 phase system. Don't worry that 3 x 277 adds up to more than 480v. A 277v line is typically one phase of a 480v 3 phase system.

not enuff information 20 leds in parallel at 2.5v about 2W a motor at 480V 3 phase 600 w or 3/4 hp
Mathematically, just divide 480 by the square root of three. Electrically, 480V refers to the line-to-line value of a three phase system. For example, measure the voltage across A-phase and B-phase and you'll get 480V. 277V is the line-to-neutral value. Measure the voltage across A-phase and the neutral conductor and you should get 277V.

yes,
The the supply stays within +/- 5% of what the motor is rated for, you can do this.
Only one neutral conductor is typically in a 3 phase panel.
Line voltage equals phase voltage multiplied by the square root of three. a.k.a. E l = E p X 1.73 In a 3 phase 480v system the phase voltage is 277v. Therefore E l = 277 X 1.73 = 480v
there isnt a high leg in a three phase 480v panel only on 240v panels
