Brushless motor using fractional slot concentrated winding has the following advantages: (1)The positioning of the motor torque is small, good in usability, small torque ripple. (2)Minister of small coil end, small end copper loss and reduced the volume of motor with copper, a hard mechanical properties, high efficiency, (3)Stator winding technology is good, simple mechanical order, good commonality, groove can be filled with rate is higher than certificate slot winding (4)Winding without overlapping, and good insulation
