An electrical assembly that with an inverter that is mounted to the field windings of a stator. The inverter has a plurality of power semiconductor packages (PSP), each of which including a semiconductor die, a plurality of electric terminals, which are electrically coupled to the semiconductor die, and a heat sink with a base, which is fixedly and electrically coupled to one of the electric terminals, and a plurality of fins that extend axially from the base in a direction away from the semiconductor die. The PSP's are arranged in a circumferentially spaced apart manner. The fins are arranged in rows and are progressively longer in length from a radially-inner most fin to a radially-outer most fin. Slots are formed in the base on a radially-inner side of the base. Each slot extends toward a radially-outer side of the base and intersects a corresponding one of the rows of fins.

An embodiment relates to a stator and a motor including the stator, the stator comprising: a stator core; a coil wound around the stator core; and an insulator disposed between the stator core and the coil, wherein the insulator includes: a body around which the coil is wound; a first guide protruding from the inside of the body; a second guide protruding on the outside of the body a first protrusion protruding outward from the lateral surface of the first guide; and a second protrusion protruding inward from the inner surface of the second guide, and an insulating member radially disposed between the first guide and the second guide is bent in a circumferential direction by means of the first protrusion and the second protrusion. Therefore, the motor can inhibit the movement and separation of insulating paper.
