The utility model discloses a powder metallurgy VVT stator. The device belongs to the powder metallurgy technology field, has solved the problem that stator structure is complicated among the prior art, the suitability is narrow, the precision is low, and including ring shape body, the body inboard is equipped with supports the stator convex structure who leans on in the rotor periphery, and stator convex structure is including first stator boss, the second stator boss of locating the upper end and third stator boss, the fourth stator boss of locating the lower extreme, and second stator bossand body junction are equipped with the U -shaped groove. The utility model discloses a set up a small amount of stator boss, not only make stator structure simpler and easy, reduce mould manufacturing cost, can hold the different shape rotors of rotor moreover, make the suitability obtain enlarging, utilize the U -shaped groove, satisfy the demand of machine oil transition, avoid setting up mistake oilhole in stator boss department, arouse the problem of stator deterioration of strength, adopt once shaping mode of powder metallurgy, make that production efficiency high efficiency, productiontechnology are succinctly changed, accurateization of precision.
