Description
An intervveaving machine and a method for producing a winding for an
electric machine
TECHNICAL FIELD
The present disclosure relates to the area of windings for electric machines. Particularly, the present disclosure relates to an intenNeaving machine arranged to produce a winding for an electric machine and to a method for producing a winding for an electric machine by using
the winding machine.
BACKGROUND
Electrical rotary machines are largely known within the area of technology. Electrical rotary machines comprise a stationary stator and a rotor that is configured to rotate in relation to the stator. Usually, the rotor is designed as an internal rotor arranged inside the stator. The stator comprises conductor coils designed as windings and an energization of the windings generates magnetic fields which, together with the magnets of the rotor, produce attractive and repulsive forces on the rotor for the purpose of achieving a rotational movement of the
rotor.
Windings of electrical rotary machines are often, so-called, wave windings, since the
windings have a wave-like form along the axial length of the rotor.
Producing windings is often time consuming and complicated. Thus, it is desirable to facilitate the processes of producing windings regarding i.a. the time- and energy
consumption.
SUMMARY lt is an object of the present disclosure to overcome, or at least alleviate, at least some of the
above-mentioned drawbacks and problems.
According to a first aspect of the disclosure, the object is achieved by an interweaving machine according to claim 1. Thus, the object is achieved by an intenNeaving machine arranged to intenNeave at least two preformed winding wires adapted for a winding of a stator of an electric machine. Each wire of the at least two winding wires has a curved form with a number of curvatures and has an extension along a main extension direction. The at least two winding wires are intended to be winded by an engagement with each other at the curvatures. Each wire comprises a pair of ends. The intenNeaving machine comprises a first
movement control part comprising:- a first receiving portion arranged to receive a first connector attached to at least one first end of at least one first wire of the at least two wires and
-a second receiving portion arranged to receive a second connector attached to at least one second end of at least one second wire of the at least two wires.
Each of the first receiving portion and the second receiving portion is arranged to move at least in a first direction and in a second direction being opposite to the first direction. The first direction and the second direction are substantially parallel to each other and in planes substantially parallel to a plane of the main extension direction of the wires. The first receiving portion and the second receiving portion are arranged to move a first distance in
the first direction and in the second direction.
The intenNeaving machine further comprises a second movement control part comprising:
- a third receiving portion arranged to receive a third connector attached to at least one third end of the at least one first wire and
- a fourth receiving portion arranged to receive a fourth connector attached to at least one fourth end of the at least one second wire.
Each of the third receiving portion and the fourth receiving portion is arranged to move in the first direction, in the second direction, and in a third direction and in a fourth direction being opposite to the third direction. The third direction and the fourth direction are substantially parallel to each other and substantially perpendicular to the first direction and to the second direction. The third direction and the fourth direction are directions towards a position of the third receiving portion or towards a position of the fourth receiving portion wherein the third receiving portion and the fourth receiving portion are arranged to move a second distance in the first direction and in the second direction, wherein the second distance is greater than the
first distance.
The interweaving machine is arranged to operate according to a predefined sequence of movements of the first-, second-, third- and fourth receiving portions in corresponding first-, second-, third- and fourth directions in order to produce the winding of the at least two
preformed winding wires.
Because the winding can be produced by the machine, the winding can be produced effectively and during a shorter time period comparing to present methods for production windings where it is often done by hand. Further, because the winding can be produced automatically by the machine a human involvement can at least be reduced. Thereby, the
above-mentioned object is achieved.Optionally, each of the first receiving portion and the second receiving portion is arranged to move in the third direction and in the fourth direction. Thereby the winding procedure can be yet facilitated because the winding wires can be angled in relation to each other also at the
first movement control part.
Optionally, the intenNeaving machine comprises a control unit arranged to control the movement of the first-, second-, third- and fourth receiving portions in corresponding first-,
second-, third- and fourth directions.

supporting unit.
Optionally, the supporting unit comprises a substantially horizontal flat disc arranged to
support the at least two winding wires.
Optionally, the intenNeaving machine comprises a number of support members arranged at the supporting unit and arranged to move in relation to the supporting unit in the third direction and in the fourth direction to release the support of the at least t\No winding wires and to achieve a support of the at least two winding wires respectively, wherein the number of the support members corresponds to the number of curvatures for each of the at two winding wires except for the outermost curved portions of each wire. Thus, the interweaving procedure can be facilitated by using the support members supporting the winding wires and releasing the support according to a predefined sequence of movements of the support
members in order to achieve a desired winding.
Optionally, the intenNeaving machine comprises a winding preventing means arranged to prevent winding of the at least two winding wires at at least one of the number of curvatures of the wires during the predefined sequence of the movements, wherein the winding is prevented by separating the wires by an action of the winding preventing means at the at least one of the numbers of the curvatures. Thus, a desire winding can be achieved with desired number of windings between the winding wires. The support members can be used
for preventing winding of the at least two winding wires.
According to a second aspect of the disclosure, the object is achieved by a method for
producing a winding for a stator of an electric machine according to claim 8. Thus, the objectis achieved by a method for producing a winding for a stator of an electric machine by using a winding machine according to any of the embodiments described herein. The winding machine is arranged to interweave at least two preformed winding wires, wherein each wire of the at least two winding wires has a curved form with a number of curvatures and has an extension along a main extension direction. The at least two winding wires are intended to be winded by an engagement with each other at the curvatures wherein each wire comprises a pair of ends.
The method comprises:
-positioning a first connector attached to at least one first end of at least one first wire of the at least two wires in the first receiving portion of the first movement control part of the winding machine,
-positioning a second connector attached to at least one second end of at least one second wire of the at least two wires, in the second receiving portion of the first movement control part of the winding machine,

performing a predefined sequence of movements of the first-, second-, third- and fourth receiving portions in corresponding first-, second-, third- and fourth directions in order to
produce the winding.
Because the winding can be produced by the machine, the winding can be produced effectively and during a shorter time period comparing to present methods for production windings where it is often made by hand. Further, because the winding can be produced automatically, a human involvement can at least be reduced. Thereby, the above-mentioned
object is achieved.
Optionally, the first connector and the third connector are attached to a number of first wires forming a first wire mat and the second connector and the fourth connector are attached to a number of second wires forming a second wire mat, wherein the method comprises winding
the first mat and the second mat.
Optionally, the number of the first wires in the first wire mat is equal the number of the
