The utility model discloses a permanent magnet synchronous motor stator and rotor assembly and a permanent magnet synchronous motor, the permanent magnet synchronous motor stator and rotor assembly comprises a stator core, the stator core is provided with a plurality of stator slots at equal intervals, and stator teeth are formed between two adjacent stator slots. The outer diameter R1 of the stator iron core is 360-450 mm, and the inner diameter R2 of the stator iron core is 0.56-0.66 times of the outer diameter R1; the number Q of the stator slots is 50-60, the slot bottom of each stator slot is arc-shaped, the radius r of the slot bottom is 4.5-8.5 mm, and the slot depth h is 35-55 mm. The stator teeth comprise neck parts and wing parts which extend along the radial direction of the stator core, and the neck width of the stator teeth is # imgabs0. According to the utility model, the ratio of the inner diameter to the outer diameter of the stator core is optimized, and the related parameters of the stator s
