The invention relates to a concentrated winding built-in permanent magnet synchronous motor used for a new energy vehicle. The concentrated winding built-in permanent magnet synchronous motor comprises a stator, a rotor and a permanent magnet, wherein the radial section of a stator tooth is divided into two symmetrical parts via a virtual straight line which passes through the axis of the rotor in a teeth space range, and the virtual straight line is the tooth end center line of the stator tooth; a tooth surface edge part is subjected to bevelment along another virtual straight line, and the virtual straight line is a tooth end bevelment line; the tooth surface edge parts of the stator tooth are independently provided with a tooth end bevelment line; two tooth end bevelment lines are not coincident and are symmetrical by taking the tooth end center as an axis of symmetry; and the tooth surface of the stator tooth is provided with two tooth surface grooves, a tooth surface groove axis is the axis which passes
