A built -in PMSM of concentrated winding for new forms of energy car

The utility model relates to a built -in PMSM of concentrated winding for new forms of energy car, including stator, rotor and permanent magnet, at a tooth pitch within range, the radial cross section of stator tooth divides into the two halves of symmetry by a virtual straight line through the rotor axle center, and this virtual straight line is the increment central line of stator tooth, and flank of tooth edge part is followed another virtual straight line and is scabbled, and flat line is cut for the increment to this virtual straight line, the flank of tooth edge part of stator tooth respectively have an increment to cut flat line, coincidence and use the increment central line as the symmetry axis symmetry of flat line is cut to two increments, the stator tooth flank of tooth on offered 2 flank of tooth recesses, flank of tooth recess axis is through the axis at stator center and lies in the both ends of the increment central line of stator tooth that the increment central line of flank of tooth recess
