A rotor assembly (), comprising a rotor () and a rotor winding (). The rotor () is provided with a plurality of teeth; tooth slots are provided between adjacent teeth; the rotor () can be connected to a rotor shaft to output power; the rotor winding () is composed of coils wound on the rotor (); the rotor winding () comprises a portion extending in an axial direction parallel to the rotor assembly () and a portion extending in a plane perpendicular to the axial direction; the portion extending in the plane perpendicular to the axial direction comprises a plurality of sections; in the axial direction, the plurality of sections are in one-to-one correspondence to corresponding sides of two or more polygons, respectively. The winding method can solve the problems such as length difference of copper wires between windings due to sequential superposition of the coils in traditional windings, thus achieving the technical effects of improving the balance of the armature and minimizing the difference in resistance of windings.

Rotor assembly and motor having same

Disclosed is a planetary gear transmission box, comprising a housing portion, a first planetary gear transmission stage, and a second planetary gear transmission stage, wherein the first planetary gear transmission stage comprises a first sun gear (), a first planetary carrier (), and a first ring gear; the second planetary gear transmission stage comprises a second sun gear, a second planetary carrier (), and a second ring gear (); the first sun gear () is connected to an external input element; the first planetary carrier () is connected to the second sun gear; the second planetary carrier () is connected to an output element; the transmission ratio of the gear transmission box is greater than 25; and the second planetary carrier () is directly supported on the housing portion. The locked rotor torque of the gear box is increased, such that the output rotational speed is reduced, and thus a bearing member at the output end can be omitted.

Planetary gear transmission box

The present application relates to a planet carrier assembly for a vehicle door closing actuator. The planet carrier assembly comprises a plurality of planetary gears and a planet carrier body. The planet carrier body comprises a disc portion, a cover portion and an output shaft portion, wherein the plurality of planetary gears are rotatably mounted on the disc portion via a corresponding number of mounting shafts fixed to the disc portion, one end of the mounting shaft protruding from a central hole of the planetary gear is pressed into a corresponding receiving hole on the cover portion, and the planet carrier body is further provided with a rotation locking device to prevent the cover portion from rotating circumferentially relative to the disc portion. The planet carrier assembly according to the present application has the advantages such as low cost, high strength, and simple assembly.
