1. Handler for electronic components, comprising: a plurality of circulating carriages that can move along a circulation path, each carriage having at least one holding device for holding a component,a drive device structured to move the circulating carriages, anda stationary, annular guidance device structured to guide the circulating carriages along the circulation path, said guidance device comprising at least one guide rail formed as a continuous loop,wherein the drive device has a plurality of drive motors for moving the circulating carriages with each circulating carriage being operatively connected to its own associated drive motor. 2. Handler according to claim 1, wherein the circulating carriages can be moved independently of each other along the circulation path such that the mutual separation of the circulating carriages is variable. 3. Handler according to claim 1, wherein the guidance device comprises two annular guide rails, which are spaced laterally apart in two mutually parallel vertical planes. 4. Handler according to claim 3, wherein the circulating carriages are mounted on the two annular guide rails in the edge areas of their opposite sides. 5. Handler according to claim 4, wherein the two annular guide rails are composed of guide ridges arranged in a circular ring, and the circulating carriages have guide jaws that engage over the guide ridges. 6. Handler according to claim 3, wherein the two annular guide rails are composed of guide ridges arranged in a circular ring, and the circulating carriages have guide jaws that engage over the guide ridges. 7. Handler according to claim 1, wherein the handler has two to six circulating carriages. 8. Handler according to claim 1, wherein each circulating carriage is operatively connected to an associated assigned drive motor by means of a separate drive shaft and a drive arm that extends from the drive shaft out to the assigned circulating carriage. 9. Handler according to claim 8, wherein the drive shafts of the individual circulating carriages are arranged inside each other and are able to rotate about a common center axis. 10. Handler according to claim 9, wherein at least one of the drive shafts acts as a bearing mount for at least one other drive shaft. 11. Handler according to claim 9, wherein an electrical power transmission device is provided for transmitting electrical power between a fixed power generating source and the circulating carriages, where the power transmission device comprises slip rings, which are arranged in a fixed manner side by side along the centre axis, and brushes, which interact with the slip rings and are fixed to the drive arms. 12. Handler according to claim 11, wherein a plurality of brushes are spaced around the circumference of the slip rings. 13. Handler according to claim 9, wherein a data transmission device is provided for transmitting data between a stationary data processing installation and the circulating carriages, where the data transmission device comprises a plurality of slip-ring groups composed of slip rings, which are arranged in a fixed manner side by side along the centre axis, and collector contacts, which interact with the slip rings and are fixed to the drive arms. 14. Handler according to claim 13, wherein the slip rings of the electrical power transmission device and of the data transmission device are arranged in close proximity to each other. 15. Handler according to claim 8, wherein one of the drive shafts is connected to a vacuum/fluid transmission device aligned with it, which can be used to transmit the vacuum and/or fluid from a stationary vacuum/fluid supply source to the circulating carriages. 16. Handler according to claim 15, wherein the vacuum/fluid transmission device has a housing connected to the drive shaft so that they co-rotate, and a central piece arranged inside the housing, which can be fixed so that it is stationary in the handler, and which, via axial holes and radial holes assigned to these axial holes, creates a vacuum/fluid connection to radial through-channels of the housing, which is able to rotate with the drive shaft. 17. Handler according to claim 1, wherein the circulating carriages can be moved by linear motors, which are operatively connected to the annular guidance device. 18. Handler for electronic components, comprising: a plurality of circulating carriages that can move along a circulation path, each carriage having at least one holding device for holding a component,a drive device structured to move the circulating carriages, anda stationary, annular guidance device structured to guide the circulating carriages along the circulation path, said guidance device comprising at least one guide rail formed as a continuous loop,wherein the circulating carriages each have a base plate, and the at least one holding device comprises a plunger that can move perpendicular to the base plate of an assigned circulating carriage, and at whose front end at least one component is held by a vacuum. 19. Handler for electronic components, comprising: a plurality of circulating carriages that can move along a circulation path, each carriage having at least one holding device for holding a component,guidance means for guiding the circulating carriages along the circulation path, a drive device for moving the circulating carriages,wherein the circulating carriages are guided along their circulation path by means of a stationary, annular guidance device, which comprises at least one guide rail formed as a continuous loop,wherein the drive device has a plurality of drive motors for moving the circulating carriages with each circulating carriage being operatively connected to its own associated drive motor.
