A method for forming a dynamoelectric machine including providing a jig, arranging an inner yoke and an outer yoke on the jig, providing concentrically arranged rotor layers between the inner yoke and the outer yoke, filling spaces between adjacent ones of the concentrically arranged rotor layers with a powder which will define stator layers, pressing the powder within the spaces between the adjacent ones of the concentrically arranged rotor layers, and heating, sintering, and/or curing the pressed powder to form the stator layers between the adjacent ones of the concentrically arranged rotor layers.

A method for packaging sheet metal parts made from an electrical steel strip or sheet to form a laminated core is disclosed. In order to achieve advantageous process conditions, it is proposed that when the hot-melt adhesive varnish layers are pressurized in the axial direction of the stacked sheet metal parts, they are pressurized multiple times by means of a pressure pulse in that the pressure pulse is exerted through either an impingement with pulse pressure or a relief of pulse pressure.

A primary adhesive agent is applied to a core laminate in which separation layers are interposed between multiple blocks each consisting of a predetermined number of core constituting plates, the separation layers are removed after the primary adhesive agent is cured, a secondary adhesive agent is applied to lamination surfaces between the blocks, and the secondary adhesive agent is cured.

The invention relates to a process which is intended for producing an arrangement comprising a stator (STT) and a housing (OCS) for a dynamoelectric machine and in which a number of stator laminations (SMS) are put together to form a laminated core (SMP). The production process comprises:arranging the stator laminations (SMS) in a stack along an axial direction to form a laminated core (SMP) and-applying a composite polymer (GPF) to at least the radial outer side of the laminated core (SMP) such that one or more applied layers of the filled composite polymer (GPF) at least partially form(s) the housing (OCS). A composite polymer is a polymer in the form of a matrix in which particles are embedded. In addition, the invention also relates to an arrangement comprising a stator (STT) and a housing (OCS) of a dynamoelectric machine and also the use thereof for a process for producing or processing foodstuffs, pharmaceutical products or cosmetic products.

In an electric motor with a rotor, e.g., a rotatably mounted rotor, the rotor has a rotor shaft which protrudes through a recess of a laminated core, the laminated core has a hollow configuration, the recess of the laminated core has a non-round configuration, and the rotor shaft has a circular cylindrical lateral surface in the region covered by the laminated core in the axial direction. A radially protruding shaft collar is molded onto the rotor shaft, the laminated core is positioned against the shaft collar, an annular cavity is arranged in the shaft collar, e.g., is introduced into the shaft collar, a radial bore which passes through the shaft collar opens into the cavity, and adhesive is arranged between the laminated core and the rotor shaft and the annular cavity is at least partly filled with adhesive.
