摘要： A stator of an interior permanent magnet synchronous motor is provided. The stator spaced apart from a rotor by a predetermined gap within an interior permanent magnet synchronous motor includes a stator tooth that is circumferentially spaced apart by a predetermined distance while interposing a slot therebetween that corresponds to an exterior diameter surface of the rotor. Additionally, a stator shoe is formed at an end of the stator tooth and includes an interior diameter surface of a predetermined diameter that faces the exterior diameter surface of the rotor. A cross point between a circle has a diameter of (interior diameter of the stator shoe×1.0287×24/slot number) mm and the stator tooth is a tooth end start point of the stator tooth.
