Description
Technical Field
The invention relates to an insulating profile for electrically insulating at least one winding slot of a magnetically conductive lamination stack of an electric motor, wherein the winding slot is designed to receive, at least in sections, a winding section assigned to a winding of the electric motor. The invention further relates to an electric motor having at least one magnetically conductive lamination stack having at least one winding slot for receiving, at least in sections, a winding section of a winding assigned to the electric motor, and an insulation profile for electrically insulating the at least one winding slot.
Background
Lamination stacks for stators and rotors of electric motors are known from the prior art. Such a lamination stack is produced from a plurality of thin laminations or sintered soft iron and in segmented or non-segmented form and usually has radially inwardly or outwardly directed teeth which are provided with winding segments of a stator winding or a rotor winding. In order to ensure reliable electrical insulation of the lamination stack with respect to the winding segments, it is also known to provide insulation paper between the winding segments and the teeth or to blank the insulation paper into corresponding winding slots formed between adjacent teeth.
Disclosure of Invention
The invention relates to an insulating profile for electrically insulating at least one winding slot of a magnetically conductive lamination stack of an electric motor, wherein the winding slot is designed to receive, at least in sections, a winding section assigned to a winding of the electric motor. The insulating profile is made of an electrically insulating plastic material and has dimensions corresponding to the dimensions of the associated winding slot at least within specified manufacturing tolerances, wherein the insulating profile has a through-going longitudinal opening for receiving the winding section at least in sections, wherein the insulating profile has a length which is greater than the height of the magnetically conductive lamination stack.
The invention thus makes it possible to provide a new slot insulation in the form of an insulation profile while maintaining all the required insulation spacing and air gap and creepage distances. Furthermore, the insulating profile can be produced and assembled inexpensively as a similar component with a comparatively simple geometry. The complex tool for injection molding the lamination stack can be dispensed with without any replacement. The insulating profile can be mass-produced without difficulty by cutting the continuously extruded insulating profile to length for different motor lengths, i.e. in particular for different length dimensions of the lamination stack, wherein other components, such as the base plate and the connecting plate, can be kept unchanged. In addition, a secure position fixing of the insulating profile in the lamination stack can be achieved by means of a latching connection with the teeth of the lamination stack.
The insulating profile preferably has a cross-sectional geometry which is at least approximately omega-shaped.
In this way, a particularly reliable seating of the insulating profile in the winding slot is achieved when the lamination stack is embodied as a stator lamination stack.
Preferably, the insulating profile can be received in the winding slot substantially in a form-locking manner.
Thereby, air-filled voids that may lead to magnetic losses are reduced.
According to one embodiment, the insulating profile has two legs, the ends of which can each be latched to the front edges of the opposing teeth of two adjacent teeth of the magnetically conductive lamination stack in order to be fixed in the circumferential direction.
This results in a secure fastening of the insulating profile in the winding slot.
According to one embodiment, the length of the insulating profile is predefined in such a way that the insulating profile received in the winding slot projects beyond the two axial ends of the lamination stack.
This results in a seamless insulation transition to the base plate and/or the connection plate of the associated electric motor.
Preferably, the insulating profiles projecting beyond the two axial ends of the lamination stack can overlap at least one electrically insulating axial base plate of the magnetically conductive lamination stack.
In this way, a complete electrical insulation of the lamination stack can be achieved.
Preferably, the insulating profiles projecting beyond the two axial ends of the lamination stack can be connected to at least one electrically insulating connecting plate for electrically connecting an associated winding of the electric motor.
In addition to the electrical insulation of the lamination stack, an external electrical connection of the associated winding of the electric motor can thereby be simultaneously achieved.
According to an embodiment, the wall thickness of the insulating profile is at least substantially constant and is in the range of 0.1mm to 0.5 mm.
This results in a minimum magnetic loss and a maximum available installation space for the associated winding of the electric motor having sufficient electrical insulation.
Preferably, the plastic material is polyphenylene sulfide or a liquid crystal polymer.
Thus, according to the so-called "underwriters laboratories" (UL) list, the insulating profiles have a sufficiently difficult or hard flammability and electrical insulation rating in the temperature range required for the electric motor. When the requirements are low, polyamide 6 can be used, for example. However, other materials can alternatively be used which likewise meet the required UL list at the respective requirement or a predetermined wall thickness of the insulating profile.
According to a further development which is advantageous in terms of technology, the lamination stack is constructed in the manner of a stator lamination stack or a rotor lamination stack.
The insulating profile can therefore be used extensively for stator and/or rotor lamination stacks of electric motors and can be used as an inner or outer rotor independently of the motor design.
According to one embodiment, the lamination stack is formed as a laminated lamination stack or as a lamination stack sintered from soft iron.
The insulating profile can thus be used for a wide range of different types of construction of the motor lamination stack.
The invention further relates to an electric motor having at least one magnetically conductive lamination stack having at least one winding slot for receiving, at least in sections, a winding section of a winding assigned to the electric motor, and an insulation profile for electrically insulating the at least one winding slot. The insulating profile is made of an electrically insulating plastic material and has dimensions corresponding to the dimensions of the associated winding slot at least within specified manufacturing tolerances, wherein the insulating profile has a through-going longitudinal opening for receiving the winding section at least in sections, wherein the insulating profile has a length which is greater than the height of the magnetically conductive lamination stack.
The invention thus enables a significant improvement in the manufacturing process of the motor while maintaining all required insulation spacing and air gap and creepage distances at the same time.

Detailed Description
Fig. 1 shows an electric motor 100, which is embodied as an internal rotor motor, having a substantially cylindrical rotor core 150 and a rotor shaft 152. The rotor core 150 is coaxially positioned in the approximately hollow cylindrical stator core 200. The rotor shaft 152 is mounted with the rotor core 150, which is arranged on it in a rotationally fixed manner, on both sides of the rotor core 150 about the longitudinal center axis 124 on rolling bearings 110, 112, which are received in the motor housing 102, for example. The stator core 200 is preferably constructed in the form of a magnetically conductive, laminated or sintered stack of laminations 202 that functionally form a stator stack of laminations 204. Rotor core 150 is illustratively constructed in the manner of permanent magnet assemblies 156. Alternatively, however, it is also possible for rotor core 150 to be designed as a lamination stack and stator core 200 to be designed as a permanent magnet assembly.
It is noted that the motor 100 of fig. 1 is only schematically illustrated, since the construction and function of suitable motors are sufficiently well known from the prior art, so that a detailed description of the motor 100 is dispensed with here for the sake of brevity and brevity of description. Furthermore, it is to be noted that the electric motor 100 is shown as an inner rotor motor only schematically and without limiting the invention, since the invention can also be applied when using an outer rotor motor.
Fig. 2 shows the stator core 200 of fig. 1 with a lamination stack 202 forming a stator lamination stack 204, which lamination stack 202 has, for example, only six winding slots 210 of the same type, which extend axially and are of a through-configuration and in each of which an insulating profile 220 is received in a substantially form-fitting manner. The six insulating profiles 220 preferably each have a longitudinal opening 222 running through them in the axial direction.
The geometric dimensions, in particular the circumferential profile, of the insulating profiles 220 are each determined in such a way that they correspond, at least within specified manufacturing tolerances, to the associated dimensions of the stator lamination stack 204, in particular the circumferential geometry or the cross-sectional geometry of the winding slots 210. The formation of an air-filled hollow space, which leads to a weakening of the magnetic flux, between the insulation profile 220 and the winding slot 210 is thereby largely prevented. The magnetically conductive stator lamination stack 204 has a height 214 or axial structural length such that the insulating profiles 220 inserted into the winding slots 210 protrude at least slightly beyond the stator lamination stack 204 at least on one side and preferably on both sides.
The insulating profile 220 is preferably made of an electrically insulating and mechanically loadable plastic material, such as polyphenylene sulfide, or of a liquid crystal polymer, and can be produced in a simple manner in terms of production technology by continuous extrusion of the plastic material and cutting to length of correspondingly long sections. Alternatively, the insulating profile 220 can also be produced as a shape-dependent injection-molded part. It is noted, however, that other possible manufacturing methods for manufacturing the insulating profile 220 can also be used. Furthermore, insulating profile 220 can be matched in a simple manner by appropriate cutting to stator lamination packs having different heights or axial lengths, which are required for the realization of motors having different output capacities. Accordingly, insulating profile 220 can be used widely for different motor types and power classes.
Fig. 3 shows the stator core 200 of fig. 2 with a lamination stack 202 with six winding slots 201 forming a stator lamination stack 204 and with insulating profiles 220 arranged therein, which preferably each have a substantially omega-shaped cross-sectional geometry. Furthermore, stator core 200 has six teeth 230 which point radially inward and are spaced uniformly apart from one another in the circumferential direction and on which two tooth leading edges 232, 234 which point away from one another and which each have an approximately ring segment-shaped cross-sectional geometry are formed in an integrated manner, which tooth leading edges are not provided with reference numerals in their entirety for reasons of better graphical overview. The winding slots 210 are each arranged centrally between two adjacent teeth 230 and each extend perpendicularly to the plane of the drawing.
Fig. 4 shows the insulating profile 220 of fig. 3, wherein the geometric dimensions of the insulating profile 220, in particular the cross-sectional geometry or the circumferential profile of the Ω shape, are further characterized by a maximum width 250 and a maximum height 252 with a length 254 or a maximum axial structural length. The length 254 is selected here such that the insulating profile 220 received in the associated winding slot projects slightly beyond the winding slot, preferably on both sides. The wall thickness 256 of the insulation profile 220 is approximately constant and in the range of 0.1mm to 0.5mm, including the interval boundaries.
Fig. 5 shows the insulating profile 220 of fig. 4, wherein the approximately Ω -shaped cross-sectional geometry or circumferential profile of the insulating profile 220 has a head section 260 and a base section 262 with a longitudinal opening 222. The head segment 260 preferably includes a horizontally extending base segment 264 to which oppositely inclined base walls 266, 268 are respectively connected on both sides at an angle α. Preferably, two oppositely inclined side walls 270, 272 are connected to the two base walls 266, 268, respectively, at an angle β (here, for example, about 90 °). Preferably, two at least sectionally horizontally extending legs 274, 276 of the base section 262 are connected to the two side walls 270, 272, the hook-shaped curved leg ends 278, 280 of the legs facing one another without the longitudinal opening 222. The base walls 266, 268, the side walls 270, 274 and the legs 274, 276 with their hook-shaped configured leg ends 278, 280, respectively, are preferably configured as mirror images of each other. The omega-shaped cross-sectional geometry or circumferential profile of the insulating profile 220 is preferably designed such that it can be received in a substantially form-fitting manner in the winding slots of the stator lamination stack 204 from fig. 2.
Fig. 6 shows the winding slots 210 of the stator lamination stack 204 from fig. 2, into which the insulating profiles 220 from fig. 2 are inserted with their longitudinal openings 222 opening radially inward. In order to ensure a secure position fixing of the insulating profile 220 in the winding slot 210, the hook-shaped leg ends 278, 280 can be latched to the tooth front edges 232, 234 of two adjacent teeth 230 facing each other. For this purpose, the tooth front edges 232, 234 preferably have small undercuts 240, 242, respectively, against which the hook-shaped leg ends 278, 280 of the insulating profile 220 snap-lock. The two undercuts 240, 242 are preferably each realized by a small radially outwardly directed thickening.
In order to achieve a very flush termination of the insulating profile 220 with the cylindrical opening 206 for the rotating rotor core 154 of fig. 1 in the stator lamination stack 204, in the region of the tooth leading edges 232, 234, in each case one groove- like recess 244, 246 is preferably provided, which is directed radially inward and is slightly inclined on one side and in which the chamfered longitudinal edges 282, 284 of the leg ends 278, 280 are preferably likewise fixable by means of a small undercut detent, so that a flush termination of the leg ends 278, 280 of the insulating profile 220 with the opening 206 is ensured and, in cooperation with the undercuts 240, 242, a particularly secure seating of the insulating profile 220 in the winding slots 210 of the stator lamination stack 204 results.
Fig. 7 shows the winding slots 210 of fig. 6 of the stator lamination stack 204 of the stator core 200, in which the insulation profiles 220 are received, into which the two winding segments 300, 302 are inserted as part of the windings 350 of the stator core 200. On both sides of the longitudinal opening 222 of the insulating profile 220, a particularly long insulation distance 400, 402 is preferably present between the stator lamination stack 204 and the two winding sections 300, 302 of the winding 350, which insulation distance allows a long-lasting, reliable operation of the electric motor, in particular a flashover-free and flashover-free operation, even at high operating temperatures and/or rotational speeds.
Fig. 8 shows a stator core 202 of stator core 200 of fig. 2 with a winding section 300 having a height 214 or axial structural length which is preferably slightly smaller than length 254 of insulation profile 220 of fig. 2. The axial orientation of the insulation profile 220 with respect to the winding slots 210 of the stator stack 204 is preferably determined such that the first and second axial ends 286, 288 of the insulation profile 220 project beyond the first and second axial ends 216, 218 of the stator stack 204 by approximately the same projection 290, 292, respectively.
Furthermore, an electrically insulating base plate 130 is preferably provided, which can overlap or can be axially plugged onto the first axial end 286 of the insulating profile 220. Accordingly, the preferably electrically insulating webs 140 can overlap the second axial end 288 of the insulating profile 220.
Furthermore, the base plate 130 preferably also serves for the end-side closing of the stator core 200, while the rear-side connecting plate 140 preferably simultaneously provides an electrical contact or connection to a current source outside the stator core, in addition to the closing of the stator core 200 on the rear side. Furthermore, the base plate 130 and the connecting plate 140 serve for fixing the position of the free axial ends 286, 288 of the insulating profile 220 and for guiding the winding section 300.
