The lifts motors and air conditioning pumps need three phase power but the computers and office equipment will need single phase power.

Smoke Coming Out of Electric Motor. What Happened?

Webb6 juli 2016 · In a three-phase hookup, all legs should have substantially equal voltage readings, with no dropped phase. If these readings vary by a few volts, it may be possible to equalize them by rolling the connections, taking care not to reverse rotation. The idea is to match supply voltages and load impedances so as to balance the three legs. WebbA three-phase motor usually has a self-starting mechanism. Also, in a three-phase motor, the phases are 120 degrees apart, so that a proper rotating field can be produced. In comparison, three-phase motors … display port on desktop
