A rotor device for an electric motor and/or generator with a rotor body and a plurality of magnets, wherein the rotor body comprises a rotor shaft seat and a plurality of magnet receptacles arranged coaxially with the rotor shaft seat. The magnets are rigidly positioned and mounted in the magnet receptacles by means of a plastic molding compound injected into the magnet receptacles, which plastic molding compound forms at least one cover element that covers the openings of the magnet receptacles at least partially. The cover element comprises at least one magnet wheel centering means and/or at least one magnet wheel alignment means. The invention furthermore relates to a rotor and a motor with such a rotor device as well as to a production method.

A drive including a commutator motor having a motor housing, an end shield secured to the housing, feedthroughs defined in the end shield, brushes mounted in the feedthroughs; and at least one stranded conductor forming a direct electrical and mechanical connection between a brush and the terminal contact arranged outside the motor housing.

A magnet assembly in an electric drive having a shaft. The assembly includes a permanent magnet bonded in plastic and having two protrusions. An adapter has two protrusions and two recesses. The end face of the shaft has two cavities, which receive the two adapter protrusions to mount the adapter to the shaft. The two protrusions of the magnet are received in the recesses in the adapter in order to mount the magnet to the adapter. In another embodiment the shaft has an outer circumferential surface. Here, the adapter has a recess of a first shape and a second recess for mounting the adapter onto the outer circumferential surface of the shaft and the permanent magnet has a protrusion shaped to mate with the first shape of the first recess in the adapter, and the first recess is configured to receive the protrusion to mount the magnet to the adapter.

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.

A pump with an integral, electronically commutated, direct-current motor () with permanent magnetic inner rotor disposed in a wet chamber, which forms with a turbine pump wheel () a compact, structural pump-rotor unit (), a claw-pole stator () positioned in a dry chamber (), the claw-pole stator () having four claw-pole plates (') made of a soft magnetic material, a ring-shaped winding () and a claw-pole stator () including a soft magnetic back-iron ring () mounted on the claw-pole plates (&#x2032;) and disposed around the winding () and a separating can (), which separates the dry chamber from the wet chamber (), characterized in that the claw-pole plates (&#x2032;) and additional claw-pole plates (&#x2032;) are stamped and bent together, in which a plate strip for the additional claw-pole plates (&#x2032;) contains a central borehole from a previous work step.

Pump having an integrated electronically commutated direct current motor

An electronically commutated DC motor has a stator wound with a multi-phase stator winding, a permanent magnet rotor mounted rotatably about a motor axis, a circuit board, a guide plate electrically connected to the winding and a housing component. In one implementation, a DC motor can easily be manufactured with the fewest possible process steps, which exhibits a short axial length and a low weight as well as good heat-dissipation properties. It is also an object of the invention to create a DC motor with integrated electronics, whose motor interior can be filled with oil, and which holds the electronics sealed against this oil. For reasons of logistics, an attempt is also made for partial components, such as the electronics, to be designed such that they are capable of complete prior assembly and testing.

Electronically commutated dc motor, in particular for an oil pump

An electrically commutated DC motor () for a liquid pump () with a pump housing () with a suction connector () and a pressure connector () for connection to a hydraulic circuit, an essentially disk-like pump rotor () mounted to rotate in the pump housing, consisting of an impeller () with several pump vanes and a permanent magnet (), a partition () separating a pump space () from a dry space (), the partition being arranged in an axial gap () between the pump rotor () and several axially aligned stator poles (), each provided with an insulation element () and stator windings (). The task of the present invention is to configure a DC motor, so that it can be installed simply and reliably, is designed particularly robust and therefore has very high lifetime.
