In a method for producing a cooling structure over a surface of a housing of a dynamo-electric rotational machine, at least one material is applied in layers by an additive manufacturing method to the surface of the housing, omitting at least one predefined region. As a result of the application of material, at least two elevations are formed, with a cooling channel being formed between the two elevations.

A permanent magnet for connecting with a connection device of an external rotor machine includes a north pole and a south pole as magnetic poles. A magnetic field runs from the south pole to the north pole, with a cross section of the permanent magnet having an envelope with a concave section. The envelope has, in the form of a sickle, the concave section and a convex section. The permanent magnet runs in an arcuate manner along the convex section, and the magnetic poles run in an arcuate manner along the concave section.

A permanent magnet having end surfaces and an envelope curve shaped as a biconvex lens having first and second convex portions, magnetization running in an arcuate manner along the first convex portion between a north pole and a south poles. The permanent magnet runs along the second convex portion in an arcuate manner, and at least one of the magnet's end surfaces within the envelope curve has a connection surface adapted for connecting with a connection device by fusing or by positive engagement. The rotor is preferably pressed onto the shaft of the rotor after the connection device is formed around a connection surface of the permanent magnets by injection molding.

A vacuum cleaner, comprising a housing, in which a dust chamber is embodied for housing a dust separator, which may be sealed by means of a dust chamber lid, mounted on the housing and a housing for accessory pieces which can be closed by the dust chamber lid. According to the invention, the contamination of the accessory pieces by dust from the dust chamber may be prevented, whilst maintaining easy access to the accessory pieces by means of the dust chamber lid, whereby the housing is embodied as an adjoining chamber, directly adjacent to the dust chamber which is separated from the dust chamber in a dust-tight manner by means of a separating wall. The above has the advantage of permitting a user to remove an accessory piece without getting dirty.

The vacuum cleaner also comprises a receiving compartment () for attachments (), which extends below the dust compartment () and/or the fan compartment () and can be accessed by means of an opening () in the housing (). The aim of the invention is to permit users to remove attachments () easily from the receiving compartment () that is located below the dust compartment () and the fan compartment (). To achieve this, the opening(s) () is/are provided in a lateral wall () of the housing (). This permits attachments () to be removed, without bringing the vacuum cleaner out of its normal operating position.

A drive system includes a rotary drive unit for rotating a shaft and a linear drive unit for moving the shaft in a linear direction. To improve efficiency and shelf life, an energy storage is mechanically connected to the shaft for biasing the shaft to seek a linear movement in opposition to the linear direction. The energy storage absorbs the kinetic energy of the shaft and releases it again subsequently.

A vacuum cleaner with a housing and a housing cover with a cable-pull opening in the housing cover. An electric cable has a plug on one end which can be pulled through a cut-out which is larger than the plug. During assembly the plug is pulled through the cut-out and then into a cable run area formed on one side of the cut-out and connected by a slit large enough for the cable but too small to accommodate the plug.
