20090200968 | Drive Apparatus and Method for Its Operation - A drive apparatus with at least one synchronous motor, a converter and a mechanical energy buffer able to be fed from an energy supply network, which, for converting mechanical energy into electrical current, includes a first asynchronous machine, and a method of operation for such a drive apparatus are specified, with which or in which the energy buffer, especially its first asynchronous machine is directly electrically connected via a switchover device to the at least one synchronous motor, so that the converter included in the drive apparatus is bypassed for such a switch position of the switchover device and the converter accordingly does not have to be designed for currents which flow in such a switch position of the switchover device. | 08-13-2009 |
20090206684 | MACHINE WITH DIRECT DRIVE - A machine includes a moving part and a direct drive for moving the moving part. The direct drive includes a stator and an armature unit which interacts with the stator. A coupling device couples the armature unit to the moving part to allow a movement of the moving part in relation to the armature unit. The direct drive further includes a spacer device to maintain a distance between an active region of the stator and an active region of the armature unit, thereby defining the air gap between the stator and the armature unit. | 08-20-2009 |
20090284104 | BUILT-IN MOTOR, IN PARTICULAR A BUILT-IN TORQUE MOTOR - The invention relates to a built-in motor ( | 11-19-2009 |
20090284253 | SENSOR DEVICE FOR AN ELECTRIC MACHINE - The aim of the invention is to create an inexpensive sensor system for a movable electric machine in order to determine positions, the sensor signal featuring zero crossings. Said aim is achieved by a sensor device ( | 11-19-2009 |
20100026104 | SHORT STROKE LINEAR MOTOR - The invention relates to a short stroke linear motor. In order to improve the dynamics of such a short stroke linear motor, the primary part ( | 02-04-2010 |
20100040448 | DEVICE CARRIAGE WITH INTEGRATED MOTOR PART - A carriage of an electric machine has a carriage base for accommodating an object to be moved. The carriage base is fastened to a movable primary part of a linear motor. A seat is integrally formed on the carriage base and represents the housing or a housing part fastened in or to the movable primary part. The one-part design of the seat with the carriage base increases the stability of the entire carriage, allowing a reduced wall thicknesses of the carriage and eliminating the need for additional fastening elements securing the seat to the carriage base. The weight of the carriage to also reduced. | 02-18-2010 |
20110221570 | POSITION TRANSMITTER SYSTEM - A measurement system for finding the position of a primary part of a linear motor with respect to a secondary part includes an absolute value measurement system for recording a first reference position of the primary part with respect to the secondary part, and an incremental measurement system for recording a fine position of the secondary part relative to the first reference position recorded by the absolute measurement system. The absolute value measurement system includes at least one RFID reader and at least one first RFID tag which is identifiable by the RFID reader, with the first RFID tag intended to identify the first reference position. | 09-15-2011 |
20120194122 | DRIVE FOR A MACHINE WITH PULSE DECOUPLED WORKING POINT ADJUSTMENT - A drive for providing high dynamics for a machine, such as a production machine, includes a short-stroke motor, and a pulse-decoupling device for decoupling pulses of the short-stroke motor from the machine using closed-loop control. The pulse-decoupling device has at least one component for use as a working-point adjustment device for adjusting a working point of the short-stroke motor. The pulse-decoupling device is thus able to assume the function of pulse decoupling and in addition, at least partially, the function of working point adjustment. | 08-02-2012 |
