The stator slot size is determined, be sure to put the number of turns of wire in the groove, each turn to several strands of parallel, how much is the share of the gauge. Wire winding of the three-phase induction motor stator is often used to reduce the number of shares and wound, skin effect, of course, and around the number can not be too much, so as not to cause the difficulty on the process. And when the gauge can be the same around the wire gauge, can also be a two gauge adjacent. To pay on the way that the first slot line selection, selection of gauge is relatively easy, as long as according to the current density and the size of the current can choose the winding wire gauge.
