The invention relates to a drive system comprising a control unit (1), which is connected to drive units (3a, 3b, 3c, 3d, 3e, 3f, 3g) via a data bus (2) for the exchange of data. According to the invention, one drive unit (3a, 3b) is connected to the drive motor (7a, 7b) in order to control the latt
The invention relates to a drive system comprising a control unit (1), which is connected to drive units (3a, 3b, 3c, 3d, 3e, 3f, 3g) via a data bus (2) for the exchange of data. According to the invention, one drive unit (3a, 3b) is connected to the drive motor (7a, 7b) in order to control the latter (7a, 7b) and an additional drive unit (3c, 3d, 3e, 3f, 3g) is connected to a magnetic bearing (11c, 11d, 11e, 11f, 11g) of a magnetic spindle bearing arrangement (23) in order to control said bearing (11c, 11d, 11e, 11f, 11g). The invention thus provides a drive system, in which a magnetic spindle bearing arrangement (23) is integrated.

What is claimed is: 1. A drive system comprising: a controller; first and second drive devices connected to grid power supply device and including each a control device and a 3-phase power converter, said first and second drive devices implemented with identical hardware; a data bus, connecting the
What is claimed is: 1. A drive system comprising: a controller; first and second drive devices connected to grid power supply device and including each a control device and a 3-phase power converter, said first and second drive devices implemented with identical hardware; a data bus, connecting the first and second drive devices to the controller, for exchange of data, a drive motor connected to and controlled by the first drive device; and a magnetic spindle bearing arrangement having a magnetic bearing which is connected to and controlled by two current-carrying phases of the 3-phase power converter of the second drive device, wherein the two current-carrying phases supply a current of identical magnitude but opposite polarity. 2. The drive system of claim 1, further comprising a signal converter for converting an analog actual position signal from the magnetic spindle bearing arrangement to an incremental actual position signal. 3. The drive system of claim 1, wherein a commutation angle for controlling the 3-phase power converter of the first drive device is fixed, with the fixed commutation angle being selected such that current only flows through the two current-carrying phases of the power converter of the second drive device, while a third phase of the 3-phase power converter of the second drive device is permanently de-energized. 4. A machine tool, production machine or robot having a drive system, said drive system comprising: first and second drive devices connected to a grid power supply device and including each a control device and a 3-phase power converter, said first and second drive devices implemented with identical hardware; a data bus, connecting the first and second drive devices to the controller, for exchange of data, a drive motor connected to and controlled by the first drive device; and a magnetic spindle bearing arrangement having a magnetic bearing which is connected to and controlled by two current-carrying phases of the 3-phase power converter of the second drive device, wherein the two current-carrying phases supply a current of identical magnitude but opposite polarity. 5. The machine tool, production machine or robot of claim 4, further comprising a signal converter for converting an analog actual position signal from the magnetic spindle bearing arrangement to an incremental actual position signal. 6. The machine tool, production machine or robot of claim 4, wherein a commutation angle for controlling the 3-phase power converter of the first drive device is fixed, with the fixed commutation angle being selected such that current only flows through the two current-carrying phases of the power converter of the second drive device, while a third phase of the 3-phase power converter of the second drive device is permanently de-energized.
