Abstract

The aim of the invention is to create a combined linear-rotary drive that has a compact, simple, and inexpensive design. Said aim is achieved by a combined drive comprising a linear driving device (3) and a rotary driving device (11), at least one of the two driving devices being provided with a hybrid reluctance motor. It is particularly advantageous to embody both driving devices as hybrid reluctance motors such that the rotor (4) can be produced at a low cost without permanent magnets in addition to ensuring that the drive has a very compact design.
