For the individual drive of a wheel of a motor vehicle, a planetary transmission can be combined into a single module with a motor. The planetary transmission has a sun wheel which on a motor shaft of the motor, a ring gear and a planet carrier with planet wheels which are rotationally mounted on journals. The planet carrier and the ring gear are non-rotationally connected to a support part which simultaneously forms the transmission housing, or to a driven shaft part which is rotationally mounted on the support part. The planet carrier is designed as a shaped sheet metal and comprises a sheet metal base wall which runs axially perpendicular to the axis of rotation of the planetary transmission, into which sheet metal base wall the journals are shaped in a cup shape. Projecting in the same direction as the journals from the outside circumference of the sheet metal base wall is a circumferential wall in which there is a toothed portion for the non-rotational coupling of the planet carrier with the support part or the driven shaft part. The planet wheels are held by a ring-shaped positioning disc on the shaped sheet metal part. Projecting axially from the outside circumference of the positioning disc are webs which are engaged between neighboring planet wheels, and which are welded to the sheet metal base wall. The planet carrier can be manufactured easily, and the forces which are exerted on it during operation are essentially equalized or compensated.
