摘要： A centrifugal separator for separating oil, the centrifugal separator comprising a centrifuge housing, a drive housing, a separating rotor, a shaft, a first bearing, a second bearing and a drive. A drive chamber is formed in the drive housing and a separating chamber is formed in the centrifuge housing. A partition wall is formed between the drive chamber and the separating chamber, and the partition wall comprises an opening. The shaft extends through the opening of the partition wall into the separating chamber and into the drive chamber, and the separating rotor is connected to the shaft for conjoint rotation and is arranged in the separating chamber. The drive is arranged in the drive chamber and drives the shaft, and the drive is in the form of an electric motor which drives the shaft directly in such a way that the shaft forms a motor shaft of the electric motor.

摘要： The invention relates to an external rotor device with a rotor housing designed to receive at least one rotor and with at least one sensor magnet provided on the rotor housing. The sensor magnet is arranged/can be arranged in sensory correlation with and in a predefinable relative position relative to the rotor. According to the invention, the external rotor device is characterised in that the external rotor device has at least one ring which is integrally formed on the rotor housing, the ring having at least one pocket which is arranged to receive the sensor magnet, the sensor magnet being arranged/arrangeable in the pocket in such a way and the ring being arranged/arrangeable in a predefinable relative position relative to the rotor on/in the rotor housing in such a way that the relative position of the sensor magnet relative to the rotor in at least one spatial direction is predefined by the materially integral formation, in particular at least with regard to the radial direction and also with regard to the circumferential direction and/or the axial direction.

摘要： A printed circuit board module (10) has a printed circuit board (20) with a first side (21), a second side (22) and a contact hole (30). A sleeve-type via (32) is provided in the contact hole 30. An annular ring (35, 36) is associated with the via (32), on at least one side (33, 34). The annular ring (35, 36) is arranged on the first side (21) or on the second side (22) of the printed circuit board (20). The annular ring (35, 36) is electrically connected to the via (32). The annular ring (35, 36) has an annular ring edge (40), at least in sections. The printed circuit board module (10) has a solder resist layer (50). It extends, at least in sections, from outside the annular ring edge (40) over the annular ring edge (40) to an outer region (42) of the annular ring (35, 36). An inner region (44) not covered with the solder resist layer (50), remains on the annular ring (35, 36).

摘要： A stator device with a plurality of windings, on a winding carrier, that electromotive interaction with a rotor. The windings are parallel to one another and to the center axis. The windings can be individually electrically contacted with winding terminals of a winding wire. The windings are assigned to at least two disk-shaped and/or ring-shaped electrically conductive interconnection rings so that they are electrically insulated from one another. The winding terminals are connected using the interconnection ring assigned to this terminal polarity (U; V; W) for external permanent common contact by welding hooks formed on the radial inner side on the interconnection ring. A ring-shaped deflection disk, with deflection pins, is provided in the axial direction on the interconnection end disk.

摘要： An electric motor has a motor casing (2) which has a shaft portion for accommodating a motor shaft (4), and a motor portion for accommodating motor electronics (5) and motor windings (6). The shaft portion and the motor portion are separated from each other in a sealed manner by a can (7) in the motor casing (2). The can (7) has a metal ball bearing housing (8) in which a ball bearing (9) for mounting the motor shaft (4) is fastened, and wherein the ball bearing housing (8), indirectly via the can (7), adjoins, with an intermediate gap, a casing cover (3) that forms part of the motor casing (2). The casing cover (3) acts as a heat sink, and heat generated by the ball bearing (9) during operation is dissipated onto the casing cover and into the outer environment via the ball bearing housing (8) and the can (7).
