Between angle be 45.6 °, angle is 38.4 ° between other main poles, and stator slot, stator main pole 1 and 2 are limited between main pole and main pole
Between limit stator slot 30, stator slot 31 is limited between stator main pole 3 and 4, because the angle between stator main pole 3,4 is
45.6 °, and the angle between stator main pole 1,2 is 38.4 °, so the groove area of stator slot 31 is more than stator slot 30.
Main pole 1,4 and 7 forms U phases, and main pole 2,5 and 8 forms V phases, and main pole 3,6 and 9 forms W phases.
Because the groove area of stator slot 30 is less than stator slot 31, in order to ensure every phase winding identical number of turn, real electrical machinery
Available groove area depends on stator slot 30, causes the groove area utilization rate of motor stator slot 31 to reduce, motor output torque
Reduce.
Meanwhile angle is 122.4 ° between main pole 1 and main pole 4, angle is 115.2 ° between main pole 4 and main pole 7, main pole 7
Angle is 122.4 ° between main pole 1, causes three main poles simultaneously asymmetric in the position of circumferencial direction, when U phase windings are powered,
Electromagnetic force suffered by motor stator is made a concerted effort and is not zero, and can cause the vibrations of motor stator.
