Definitions
- the invention relates to a method for producing an assembly of an electrical machine and assembly that can be produced by this method, and to an electric motor with such an assembly.
- the assembly of an electrical machine is understood to mean both a stator of an electrical machine and, under certain conditions - described below - a rotor.
- An electrical machine is both an electrical motor and an electrical generator, regardless of whether the electrical machine is designed as a rotating machine or, for example, as a linear motor.
- stator or rotor windings are either prefabricated and insulated form coils that are inserted into the open slots. When the slots are closed, the winding wires must be threaded from the face of the laminated core so that a corresponding coil is created.
- a development coming from a completely different area is to provide finely pulverized soft iron particles with a thermoplastic coating.
- An iron powder is suitable for this, in which iron particles with a diameter of approximately 20-150 ⁇ m have a coating of polyethylene of approximately 2-10 ⁇ m.
- Such powder is described, for example, in SAE Technical Paper Series, "P / M Cores for Pulsed DC Ignition Systems", David E. Gay, International Congress & Exposition, Detroit, MI, February 24-27, 1997.
- the materials described therein are suitable for carrying out the invention. However, it is also possible to use corresponding material from other manufacturers with similar properties for the process according to the invention.
- the invention is based on the problem of fundamentally simplifying this process so that it becomes significantly less expensive.
- the solution to this problem according to the invention consists in a method for producing an assembly of an electrical machine with the following steps: - Manufacturing at least part of a winding of a rotor or stator of an electrical machine; - Positioning the at least part of the winding in a mold, the cavity shape of which reproduces at least part of the assembly;
- the elaborate assembly step to insert the winding into the grooves of the sheet metal parts is evidently not necessary here.
- the assembly and alignment of the bleaching parts to one another is no longer necessary.
- the winding can be virtually completely surrounded by the soft iron particles, so that no winding heads are created.
- the wires of the winding are not received in preformed slots. Rather, the soft iron particles adhere directly to the wires of the winding, so that there is practically no air gap between the wires of the winding and the molded body made of soft iron particles (apart from the material thickness of the plastic coating of the soft iron particles).
- the soft iron particles introduced into the casting mold are mechanically compressed to such an extent before the heat treatment that none There are more air pockets in the powder made of soft iron particles or at interfaces between the powder and the coil (s). This can be done by shaking, vibrating the mold, compressing by means of a stamp, or the like. , or can also be achieved by combinations of the individual aforementioned methods.
- a recess is formed in the soft iron particles introduced into the casting mold before or during the heat treatment, in which an electronic circuit (for example a control circuit or a sensor assembly) for the electrical machine is introduced.
- an electronic circuit for example a control circuit or a sensor assembly
- the ends of the coil (s) can end in this recess, so that the electronic circuit can be connected directly to it.
- the heat treatment step is carried out in such a way that the insulation of the winding wire (made of lacquer, plastic, enamel or ceramic) is not damaged.
- the heat treatment is preferably carried out at about 250 ° to 350 ° Celsius until the soft iron particles are surrounded by a uniform, molten plastic coating, without the iron particles coming to any appreciable extent into a magnetically (or electrically) conductive connection.
- the coil forming the short-circuit rotor is produced by casting.
- the coil can be made by punching out recesses from a circular cylindrical tube made of aluminum or copper. be put. In both cases, the coil produced in this way is then surrounded with the soft iron particles and heat-treated.
- the invention also relates to an assembly for an electrical machine, in which a coil is at least partially surrounded by iron, the iron being formed by interconnected soft iron particles with a thermoplastic plastic coating.
- the invention also relates to an electrical machine with a stator and / or a rotor, which is formed by such an assembly.
- a shaft is introduced into the powder in the rotor before the compression and the heat treatment, the shaft having an outer polygon or projections, so that the shaft rotates after the compression and the heat treatment (and cooling) and is captively accommodated in the rotor assembly.
