Definitions
- the invention relates to an electric motor with at least one motor part, which has at least one cooling coil for dissipating waste heat.
- a cooling coil is usually mounted on the side of the body facing away from the coils, through which a cooling medium such as water is passed.
- a tube made of a good heat-conducting material such as copper, aluminum or the like is bent in a zigzag or meandering shape into a flat structure and fastened on the corresponding surface of the carrier body.
- the bending of the material is technically complex, since it can easily cause compression on the inside of the bend and / or cracks on the outside of the bend. Furthermore, it must be taken into account that for different types of linear motors, which differ in terms of their dimensions, different cooling coils have to be kept available, which increases the effort for production and storage.
- the object of the invention is to provide a motor part for an electric motor with a cooling coil, in which the cooling coil can be produced in a simple manner and can be adapted to different dimensions of the motor.
- the cooling coil is made up of straight cooling tubes made of a material which is a good conductor of heat and deflections, the deflections being made of plastic.
- the invention is based on the knowledge that, in the case of meandering cooling coils, the bends or deflections are normally arranged in edge regions of the body, from which little or no heat can be removed. Accordingly, deflections made of plastic material do not or only insignificantly impair the cooling capacity of the cooling coil, since in the critical areas in which a lot of heat has to be dissipated, cooling pipes made of a material with good thermal conductivity are arranged.
- Cooling coils with the desired dimensions can be produced in a modular manner, for example, by cooling pipes with a standard length being cut to length and arranged in a suitable number according to a desired dimension via the deflections.
- the deflections could consist of flexible hoses that are simply slipped over the ends of the cooling tubes or glued to them. Leakage and stability problems could, however, arise in the long term, so that this variant only appears to be suitable for engine parts in which the cooling coil is later cast with potting compound.
- the deflections are therefore preferably produced as plastic molded parts, for example from thermosets or thermoplastics by means of injection molding or the like.
- These deflections preferably have a receiving section for one end of a cooling tube or an insertion section for insertion into an end of a cooling tube on.
- the receiving section or the insertion section can be provided with sealing elements such as O-rings or the like.
- connection ends for the cooling tubes have a fixed distance.
- the deflections can also be composed of two separate knees which are connected to one another via a coupling section, the coupling section being able to be formed on one of the knees or being provided as a separate part, in particular as a tube can.
- Fig. 1 shows schematically the structure of a cooling coil from cooling tubes and deflections and
- Fig. 2 shows schematically the structure of an engine part with a cooling coil.
- the body 1 of a motor part of a linear motor is shown in broken lines in FIG. 2 in plan view.
- this is the primary part, which has 1 teeth and coils on one side of the body, in which heat is developed.
- this can also be the support plate of a secondary part that carries permanent magnets (synchronous motor) or the secondary part of an asynchronous motor in which eddy currents are generated.
- a cooling coil K made of tubular material is attached, which is constructed from straight sections 10 and deflections 12, 13 as a flat, meandering element. Coolant, which is supplied via an inlet Z, passes through the cooling coil K, absorbs waste heat from the body 1 and leaves the cooling coil at an outlet A. In contrast to FIG. 2, is shown As a rule, outlet A is routed through a pipe to the area of inlet Z.
- the cooling coil is constructed according to the invention from a plurality of straight tube sections 10 which are connected to one another via deflections, three different types of deflections 12, 13, 18 being shown in this figure.
- the deflection 12 consists of a first 90 ° knee with a first receiving section 25, an adjoining straight partial section and a second 90 ° knee with a second receiving section 26.
- annular grooves 23 for receiving O-rings 24 are formed in the receiving sections ,
- cooling tubes 10 are cut to corresponding lengths to form cooling tubes 10, the ends 11 of which are introduced into the receiving sections 25, 26 and are thus connected to one another. Accordingly, the inner diameter of the deflection 12 is selected to match the outer diameter of the cooling tube 10.
- two insertion sections 27, 28 are provided, each of which is provided with annular grooves 22 and which have an outer diameter corresponding to the inner diameter of the cooling tube 10.
- O-rings 21 are also introduced, which ensure a tight seal when plugged together.
- the diversion designated 18 in FIG. 2 is formed from a first knee 15 with two receiving sections and a second knee 19.
- the second knee 19 has a receiving section and a coupling section 17 in the form of a tube piece which engages in a receiving section of the knee 15.
- deflections shown in FIG. 2 are not complete.
- diversions are conceivable which on the one hand have an insertion section and on the other hand have a receiving section.
- a deflection with one or two insertion sections at the ends can also be formed in accordance with the deflection 18.
- the coupling section 17 it is not necessary for the coupling section 17 to be connected in one piece to an element 19. It is also conceivable to design two knees 15 with a separate tube element for a deflection corresponding to the deflection 18.
- cooling tubes for example in such a way that the end 14 for receiving an insertion section is widened in the manner of a sleeve or the end 1 1 is narrowed accordingly for insertion into a receiving section.
- the deflections are preferably molded plastic parts, the connection of which to metal parts presents no difficulties. In contrast to the connection of the same or different metals using welding, soldering, etc., there are no oxidation problems.
- the deflections can be glued to the cooling tubes; if necessary, O-rings for sealing can be dispensed with.
- the carrier body is cast with the cooling coil K in a manner known per se by means of a casting compound.
- the cooling coil K is finally fixed on the body 1, the deflections by the Potting compound can be protected against external damage and the tightness of the cooling coil can be guaranteed permanently.
