Abstract
A stator of a rotary electrical machine includes a laminated core having grooves, windings inserted into the grooves for forming a multi-phase winding system, and an insulating layer made of plastic and sprayed between partial winding overhangs of the windings of phases inserted immediately one after the other. The insulating layer is formed as a mesh-like structure having junctions and brace-like connections running between the junctions.
Claims25
A method for producing a stator of a rotary electrical machine, said method comprising:
- inserting windings of individual phases sequentially into grooves of a laminated core to form a multi-phase windings system;
- and
- spraying between insertion of a one of the windings of one of the phases and insertion of a one of the windings of a next one of the phases an insulating layer of plastic at least onto a partial winding overhang of the windings, such that the insulating layer forms a mesh-like structure having junctions and brace-like connections running between the junctions.
A stator of a rotary electrical machine, said stator comprising:
- a laminated core having grooves;
- windings inserted into the grooves for forming a multi-phase winding system;
- and
- an insulating layer made of plastic and sprayed between partial winding overhangs of the windings of phases inserted immediately one after the other, said insulating layer formed as a mesh-like structure having junctions and brace-like connections running between the junctions.
A rotary electrical machine, comprising:
- a rotor;
- and
- a stator interacting with the rotor and comprising a laminated core having grooves, windings inserted into the grooves for forming a multi-phase winding system, and an insulating layer made of plastic and sprayed between partial winding overhangs of the windings of phases inserted immediately one after the other, said insulating layer formed as a mesh-like structure having junctions and brace-like connections running between the junctions.
