| 20090039713 | Rotary Linear Drive Having A Transmitter Device - The aim of the invention is to provide a linear/rotation drive with an improved transmitter device for detecting the linear and rotational movements. For this purpose, the transmitter device ( | 02-12-2009 |
| 20090152976 | DYNAMO-ELECTRICAL MACHINE WITH TOOTH-WOUND COILS - A dynamo-electrical machine includes a stator with teeth which are aligned with respect to a rotor, wherein at least a predeterminable number of teeth are surrounded by a winding system which is arranged in slots. The slots which are formed by the teeth and designed to be open, are each closed by a slot sealing element which has an electrically non-conductive and magnetically non-permeable material in which a tooth head widening element is provided in the area of those tooth sections of the tooth heads which face the air gap. | 06-18-2009 |
| 20090160283 | Rotary/linear Drive with a Rotary Drive which is Free of Axial Forces - 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. | 06-25-2009 |
| 20090212644 | COMBINATION DRIVE WITH A HYBRID RELUCTANCE MOTOR - 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 ( | 08-27-2009 |
| 20090251013 | Electric Motor for Rotation and Axial Movement - 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 (L | 10-08-2009 |
| 20090295236 | Electric Machine Having A Rotary And A Linear Actuator - The invention relates to an electric machine which comprises a first machine part ( | 12-03-2009 |
| 20090295251 | Multipole Permanent-Magnet Synchronous Machine Having Tooth-Wound Coils - The permanently excited synchronous machine ( | 12-03-2009 |
| 20100319442 | METHOD FOR TESTING A DRIVE ARRANGEMENT AND ACCORDINGLY EQUIPPED CONVERTER - In a method according to the invention for testing a drive arrangement and an accordingly equipped converter, an actual torsional backlash of an engine brake, which is preferably configured as a spring-operated brake, is determined and compared to a permitted torsional backlash. To this end, a test torque, which is smaller than a holding torque of the brake, is moved counter to the closed brake up to a stop, preferably in both directions of rotation. The testing method can be implemented as a routine check in a converter of the drive arrangement. | 12-23-2010 |
| 20110030165 | Vacuum Cleaner - A vacuum cleaner including a housing with a dust container therein and a suction opening with a detachable connection of a suction hose to the opening. The housing having an outer wall aligned with the suction opening and the suction opening in an inner wall. The connector body of the suction hose having tubular end piece with a connecting cone insertable into the suction opening through both walls of the housing and into the dust container. | 02-10-2011 |
