<p><b>New page</b></p><div>'''Three-phase power''' is the form of [[alternating current|AC]] power often supplied in for use in powering heavy equipment (especially rotating equipment); i.e. there are a trio of supply [[conductor]]s, each of which carries power in a different [[phase]].

This allows the torque produced in an electric motor to be 'smoother' - in a motor powered by single-phase AC, the torque output will necessarily be sinusoidal, like the input voltage.<br />
<br />
The 3 phases have to be connected to the motor in the correct 'order', or the motor may rotate in the other (i.e. 'wrong') direction. There are stories of large (older) [[disk]]s, powered by 3-phase power, being connected the wrong way around - with the un-wanted result!<br />
