Patent number: 9160206Abstract: The aim of the invention is to provide an electric motor which has a high torque at low rotation speeds and a high power at high rotation speeds. The invention therefore proposes an electric motor with permanent-magnet excitation having a first active part (10), which is fitted with permanent magnets (11), and a second active part (10), which can be moved in relation to the first active part (10) by magnetic force of the permanent magnets (11). The electric motor also has a heating device (12) with which the magnetic field of at least one of the permanent magnets (11) can be weakened by heating the permanent magnets as a function of a speed of the first active part (10) in relation to the second active part (8).Type: GrantFiled: November 28, 2011Date of Patent: October 13, 2015Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Detlef Potoradi, Rolf Vollmer, Dirk Van Riesen

Patent number: 8063517Abstract: 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: GrantFiled: April 21, 2006Date of Patent: November 22, 2011Assignee: Siemens AktiengesellschaftInventors: Erich Bott, Matthias Braun, Detlef Potoradi, Holger Schunk, Rolf Vollmer
