The existing common flat stator wire type can be divided into a hairpin type flat wire winding and a straight flat wire winding. The single straight flat wire winding is convenient to manufacture and install, and when the straight flat wire winding is installed, the straight flat wire winding is directly inserted into the stator slot, and the disadvantage is that both ends are required to be welded.
