Definitions
- the invention relates to a stator for an electric drive unit according to claim 1 and a method for producing a stator for an electric drive unit according to claim 10.
- Electric motors find numerous applications in the automotive sector, such as driving fluid pumps.
- brushless electric motors include a stator with wound stator poles that form the coils and realize contacting of a winding wire or several winding wires by means of insulation displacement contacts.
- the wire When inserting the winding wire into the receiving pockets for insulation displacement contacts, the wire is subject to tensile stress.
- the tensile stress on the winding wire is increased, with the result that the winding wire can be damaged, which in turn has negative effects on the contacting.
- the winding wire may be off-center in the receiving pocket and not correctly connected to the insulation displacement contact. Clamp contact is contacted.
- a further danger is that the winding wire, which is contacted by means of the insulation displacement contact, can slip out of the insulation displacement contact under the influence of temperature changes.
- the object of the invention is to specify a stator for an electric drive unit and a method for producing a stator for an electric drive unit, in which reliable contacting of the continuous winding wire is ensured, and relative movements between the continuous winding wire and the insulation displacement contacts are reduced as well as in the method for producing a stator to produce a wire, in order to thereby reduce the wire tension at the contact point of the winding wire and the insulation displacement contact under the influence of temperature changes.
- a stator for an electric drive unit comprising a stator core with at least one stator pole; a stator winding which forms all the coils from a continuous winding wire; at least one insulating cap on which a plurality of contact-receiving pockets is arranged for receiving the winding wire; a number of deflection domes, which are arranged distributed over the circumference of the insulating cap and wire guide contours on the outer peripheral surface of the insulating cap for spacing the winding wire, the plurality of contact receiving pockets having a receiving area for the winding wire which is designed differently and the plurality of contact receiving pockets having at least include a deflection balcony (pocket elevation).
- the electric drive according to the invention is designed in particular as a three-phase brushless electric motor with 9 stator poles.
- the stator core with at least one stator pole is formed from a stamped laminated core.
- the at least one Insulating cap is applied or mounted on the stator core as an injection molded part.
- a plurality of contact receiving pockets and a number of deflection domes are arranged in the axial direction on the at least one insulating cap.
- wire guide contours for spacing the winding wire run on the outer peripheral surface of the at least one insulating cap. The wire guide contours prevent the phase wires from touching and thus avoiding a short circuit.
- the plurality of contact receiving pockets has a receiving area for the winding wire, which is designed differently.
- the individual contact pockets are designed differently.
- the individual contact-receiving pockets include at least one deflection balcony, which is formed on a radial inner surface and/or outer surface of the contact-receiving pockets.
- the receiving area of the contact-receiving pockets comprises an upper and a lower elastic partial area.
- elastic can mean that the partial areas consist of an elastic material, for example, or are designed to be elastically flexible.
- the entire contact-receiving pocket can also be designed to be elastically yielding.
- the receiving area can also advantageously have a support area for the winding wire between the upper and the lower partial area.
- the support area is designed, for example, in the form of a sloping contour between the upper and the lower partial area, so that the winding wire can rest on it when it is being wound through.
- the support area increases the support height of the winding wire, so that the winding wire does not migrate in the y-direction (axial direction).
- the lower partial area is narrower than the upper partial area. This means that the legs in the lower part of a have a smaller distance from each other than in the upper part.
- a support area for the winding wire can advantageously be formed at the upper end (viewed in the y-direction or axial direction).
- the lower partial area preferably has a groove base.
- the lower partial area is preferably adapted to a diameter of a winding wire, preferably that the width of the lower partial area corresponds to the diameter of the winding wire.
- the upper and lower sections have opposite legs, with the winding wire being fixed by the legs in the lower section.
- the legs in the lower part are elastic.
- the limbs of both sections or the limbs of only one side of the lower and/or the upper section to be elastic.
- the lower partial area has webs on the opposite legs, which extend to the bottom of the groove. This can only be provided for one, two or any number of contact receiving pocket(s).
- the upper area of the webs enables an even winding wire support without tensile stress. A central positioning of the winding wire is advantageously ensured.
- the wire guide contours are partially formed circumferentially on the outer surface of the at least one insulating cap.
- the wire guide contours do not run radially around the entire insulating cap, but are primarily provided in the area of the contact receiving pockets, the deflection domes and partially on the insulating cap.
- a guide for the winding wire when winding of the stator and spacing of the individual phase wires is hereby guaranteed.
- the wire guide contours are preferably provided in the form of grooves on the outer surface of the contact receiving pockets, the deflection dome and partially on the insulating cap.
- a stator of an electric drive unit having a stator core with at least one stator pole, at least one insulating cap on which a plurality of
- Contact receiving pockets is arranged for receiving the winding wire, a number of Umlenkdomen, which are arranged distributed over the circumference of the insulating cap and includes wire guide contours on the outer peripheral surface of the insulating cap for spacing the winding wire.
- the plurality of contact receiving pockets has a receiving area for the winding wire, which is designed differently. Furthermore, the majority of
- the method is characterized by the following method steps: a) fixing the beginning of a winding wire on an auxiliary contact carrier; b) Fline introduction of the winding wire in the x-direction into a first
- the winding wire Before the stator core is wound, the winding wire is fixed with a winding wire start on an auxiliary contact carrier. Fixation in this context can mean holding or temporarily clamping the winding wire on both sides or on one side.
- the winding wire When the winding wire is guided in the x-direction (radial direction) into the first contact receiving pocket, it is guided straight in without forming or bending a wire loop such that the wire is positioned at a distance from the bottom of the slot. The winding wire is therefore not in contact with the bottom of the slot and is positioned on the contact area in the first contact-receiving pocket.
- Straight guidance of the winding wire is to be understood, in particular, as guiding the winding wire parallel to the legs in the contact-receiving pocket, as a result of which an oblique or eccentric positioning of the winding wire is avoided.
- the winding wire is then led out of the first contact-receiving pocket towards the first stator pole.
- the entry and exit of the winding wire takes place on the entry and exit side of the contact pocket without tensile stress and does not run askew in the contact pocket in the y-direction (axial direction).
- a wire loop is formed at the wire exit of the contact pocket and led to the first stator pole.
- the continuous winding wire is guided to a second contact receiving pocket via wire guide contours on the at least one insulating cap.
- the wire guide contours run parallel to one another, so that there is no contact between the winding wires and a short circuit is advantageously prevented.
- the entire stator core is wound through to form the coils and one end of the winding wire is fixed on the auxiliary contact carrier.
- a tool is preferably moved down in the axial direction to the at least one deflection balcony at a certain distance from the contact pockets that accommodate the start and end of the winding wire, and the start and end of the winding wire are severed in front of the contact pockets.
- the tool can be designed, for example, as a cutting stamp or a sword, but also as a cutting tool that is conventionally known to the person skilled in the art.
- the beginning and end of the winding wire are severed in front of the contact pockets and not in the contact pocket itself. According to the present invention, the start of the winding wire and the end of the winding wire are not arranged in a common contact-receiving pocket.
- the tool After cutting through the beginning and end of the winding wire, the tool is lifted in the axial direction. The tool is then moved in the radial direction up to a stop point for the tool. The movement of the tool simultaneously moves the severed winding wire start and the winding wire end in the direction of the coil through the tool up to the stop point of the tool.
- the movement of the tool in the axial direction and radial direction and the stop point for the tool are defined and specified as parameters in the tool.
- the winding wire is contacted in the contact receiving pockets by means of insulation displacement contact, with the receiving area being elastically flexible.
- a suitable insulation displacement contact is inserted into the contact receiving pocket(s) for electrical contacting of the winding wire.
- the receiving area of the at least one contact-receiving pocket has a support area that is elevated in the y direction (axial direction), which prevents the winding wire from migrating in the axial direction.
- the receiving area of the contact receiving pockets is designed to be elastically yielding, so that the winding wire takes place without damage or a change in cross section or position of the winding wire when contact is made by means of insulation displacement contact.
- the winding wire is fed into and/or out of a contact-receiving pocket with a small, preferably acute, bending radius in order to form a corresponding wire loop (or wire loop or wireless) with a narrow, preferably acute bending radius at the entry and exit of the at least one to form a contact pocket.
- the winding wire is applied closely to the contact-receiving pocket, ie at a small distance from the contact-receiving pocket, while maintaining the necessary wire tension. Due to the close contact of the winding wire, the winding wire is laid with a tight bending radius.
- the winding wire after being led out of the contact-receiving pocket, is routed via at least one deflection dome and/or at least one deflection balcony to a further contact-receiving pocket or, alternatively, to a further coil. This ensures optimal guidance of the winding wire when winding.
- the start of the winding wire and the end of the winding wire are fixed in front of the contact-receiving pockets by the webs on the opposite legs in the lower partial area when the tool cuts them through.
- front of the contact-receiving pockets means the radial outside of the contact-receiving pockets while maintaining a certain distance from the contact-receiving pocket.
- the winding wire is pressed onto the bottom of the slot and fixed in at least one contact-receiving pocket within the lower partial area when making contact by means of insulation displacement contact. This prevents the winding wire from slipping or slipping out of the corresponding contact-receiving pocket.
- the invention also relates to a pump with a previously disclosed stator of an electric drive unit, in particular an electric motor.
- Devices of this type can be used in particular in oil pumps, oil mist separators or in other types of liquid pumps, for example in the automotive sector or in the household appliance sector.
