Publication number: 20090251013Abstract: The invention relates to a combination drive with a short axial length and a high magnetic capacity. According to the invention, an electric motor comprises a rotational drive device with an outer rotor (AR), and a linear drive device with an outer rotor (AT) or an inner rotor with bearings in the active part. The outer rotor (AR,AT) can be mounted by means of hydrostatic bearings (L1,L2), indirectly by means of a shaft (W), on the stators (SR,ST) of the two drives. Said bearings (L1,L2) are axially arranged inside the outer rotors (AR, AT), presenting a short structural form of the combination drive. Furthermore, the bearings are not located in the magnetic action interstice of the drives, so that they do not influence the capacity of the machine.Type: ApplicationFiled: December 13, 2005Publication date: October 8, 2009Applicant: SIEMENS AKTIENGESELLSCHAFTInventors: Rolf Vollmer, Erich Bott, Matthias Braun, Holger Schunk

Publication number: 20090212644Abstract: 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.Type: ApplicationFiled: April 21, 2006Publication date: August 27, 2009Applicant: Siemens AktiengesellschaftInventors: Erich Bott, Matthias Braun, Detlef Potoradi, Holger Schunk, Rolf Vollmer

Publication number: 20090160283Abstract: The aim of the invention is to provide a linear rotation drive wherein the oscillating torques are reduced to a minimum and whose rotation drive is devoid of axial forces. For this purpose, a magnet of the linear rotation drive is provided with sloped sections or a plurality of magnet sections is configured to give at least two sloped magnet arrangements which are symmetric to a line extending in the circumferential direction of the linear rotation drive. Oscillating torques can also be avoided by distributing the magnets across the circumference of the rotor or stator in an uneven manner. Favorable results can be obtained when the least common multiple of the number of grooves and the number of poles is as high as possible.Type: ApplicationFiled: November 16, 2005Publication date: June 25, 2009Inventors: Erich Bott, Matthias Braun, Holger Schunk, Rolf Vollmer
