20160141940 | TRANSDUCER DEVICE WITH FORM-FITTING CONNECTION - A transducer device for attachment to one end of a shaft of an electric drive, the shaft having a shaft axis. The transducer device includes at least one recess in the shaft end. Means are provided for engaging the transducer device with the at least one recess to create a form fitting connection acting in the direction of the shaft axis. Finally, a securing means is provided for preventing detachment of the form-fitting connection. | 05-19-2016 |
20150357872 | PERMANENT MAGNET ROTOR FOR AN ELECTRINICALLY COMMUTATED DC MOTOR - In a DC motor, a permanent magnet rotor comprising a shaft, a rotor sheet packet supported by the shaft, which rotor sheet packet comprises close to the periphery thereof completely closed and tangentially extending rectangular recesses for receiving planar permanent magnet plates. At least one permanent magnet plate is accommodated in each recess, the permanent magnet plates are held by spring elements free of play by force locking, the recesses have free spaces connected to the permanent magnet plates in the tangential direction, which free spaces extend across the major part of the side surfaces of the permanent magnet plates and the rotor sheet packet consists essentially of a radial outer annular region and a radial inner core region, wherein the annular region in a large part is delimited by the recesses and the free spaces and is integral with the core region via thin radial webs. | 12-10-2015 |
20150226270 | ELECTROMOTIVE DRIVE - Electromotive drive used with an electric motor having a rotor with a motor shaft in first and second bearings and a working shaft in third and fourth bearings. The drive includes a shaft coupling for joining the motor and working shafts to ensure transmission of torque and radial force from the motor shaft to the working shaft, centering the motor and working shafts, not transmitting any axial force and compensating for any misalignment of the motor and working shafts; a coupling-contiguous end shield; and a coupling-contiguous ball bearing having an outer ring, wherein the motor shaft is mounted axially by means of the ball bearing, and the outer ring of the ball bearing is not fixed radially to the end shield, so that there is no redundancy despite double mounting of the motor shaft to the first and second bearings and the working shaft to the third and fourth bearings. | 08-13-2015 |
20150211523 | CENTRIFUGAL PUMP IMPELLER - A centrifugal pump impeller in an electromotive centrifugal pump, the impeller including a base body having a bearing to which is attached, on a first end, a permanent-magnetic rotor and, on a second end, a cover disk that is mounted on the base body; and a plurality of pump blades made of first and second parts, the first part being a base blade segment attached to the base body thus forming a first unitary piece and a cover disk blade segment attached to the cover disk thus forming a second unitary piece. | 07-30-2015 |
20140172242 | VEHICLE SEAT DRIVE SYSTEM WITH NETWORK CONNECTIVITY - A vehicle seat drive system, in particular an airplane passenger seat drive system, not requiring special software. The systems will be adaptable to new conditions over the course of the life of the installation thereof. The systems is monitorable at any time, and is capable of automatically reporting the occurrence of system faults. To accomplish this a direct link to a network that can be connected to the internet is provided. | 06-19-2014 |
20140152132 | ACTUATOR UNIT WITH CONDUCTOR STAMPING - An actuating drive having a housing which comprises receptacles for a step-down gear mechanism and for a very small electric motor, wherein the motor receptacle is connected to a terminal cover. The very small electric motor is held securely without play. The terminal cover comprises a conductor stamping which is encapsulated with plastic material and has motor contact areas which interengage with connection lugs of the very small electric motor, and in that the baffle plate has retaining regions which interengage with housing elements on the housing. | 06-05-2014 |
20130320802 | Stator of a Claw-Pole Motor - A claw-pole motor for driving a centrifugal pump; consisting of stator laminations in the form of annular discs with claw poles adjoining said stator laminations, which claw poles are arranged opposite permanent-magnet poles of a rotor, a ring-shaped winding and an insulating body, which is arranged between the stator laminations and the winding, and a magnetic return path ring, which is arranged radially around the winding and the stator laminations and bears fixedly against the stator laminations. The claw pole is achieved by the magnetic return path ring comprising at least two lamination rings, which are nested coaxially one inside the other and each have at least one cutout, and being the cutouts are offset with respect to one another through an angle such that said cutouts do not overlap one another, wherein the two cutouts define two angular ranges α1, α2, the lamination rings are connected fixedly to one another at a first connection point, which is removed from the cutouts, in the angular range α1 and likewise at another second connection point, which is removed from the cutouts, in the angular range α2. | 12-05-2013 |
