Group, a kind of method be each extremely under be uniformly divided into three equivalency ranges, each facies tract occupies 60 ° of electrical angles；Another method
It is that the extremely shared scope of each pair is uniformly divided into trisection, each facies tract is occupied 120 ° of electrical angles.60 degree of facies tracts are commonly used, because
60 degree of facies tracts have synthesis potential higher than 120 degree of facies tracts, and winding utilization is high.
The number of stator slots continuously occupied per same phase winding under extremely per the extremely lower scope occupied per phase winding, referred to as phase
