Definitions

  • the invention is based on a rotor for an electric motor or on a method for producing the rotor according to the preamble of claim 1 and claim 6.
  • the individual, insulated winding wires of the rotor or armature winding are inserted m on the circumference of the axial grooves, which are offset in the form of a laminated laminated core, with the end faces of the individual ones
  • Coil winding wires protrude as so-called winding heads on the two end faces of the rotor body.
  • the individual connecting wires to the winding coils differ from the connecting lugs m formed on the individual commutator bars
  • the rotor according to the invention or the method according to the invention for producing the rotor with the characterizing features of claim 1 or claim 6 has the advantage that standard methods already used for rotor winding can be used without requiring special adaptations or additional parts to increase the stability of the jumper wires, so that no more vibrational breaks can occur during operation, particularly during shaking tests. It is particularly advantageous that the rotor according to the invention is suitable for high speeds. Advantageous further developments and improvements of the rotor specified in claim 1 or the method specified in claim 6 are possible through the measures listed in the subclaims.
  • the armature or rotor 1 for an electric motor shown in perspective in the drawing has a rotor body 4 designed as a laminated laminated core and a collector or commutator 7.
  • the rotor body 4 and the commutator 7 are both housed in a rotationally fixed manner on a common rotor shaft 9.
  • the rotor body 4 has axial grooves 11 distributed over the circumference, in which an armature or rotor winding 13 is wrapped.
  • the individual insulated rotor winding wires 14 of the rotor winding 13 are inserted in several positions in the axial slots 11 and form individual winding coils which are connected in an electrically conductive manner to the individual commutator segments 16 of the commutator 7 via connecting lugs 18.
  • the commutator lamellae 16 are arranged next to one another in the usual manner on the circumference of an insulating material body with a non-rotating seat on the rotor shaft 9 and not shown in the drawing, and extend over the entire axial length of the insulating material body.
  • the individual commutator lamellae 16 are provided with the connecting lugs 18, which are preferably formed in one piece, also called commutator hooks.
  • the connecting lugs 18 are angled on the end face of the commutator bars 16 facing the rotor body 4 and bent in the direction of the commutator bars 16 so that the individual connecting lugs 18 enclose a small acute angle with their commutator bars 16.
  • Connecting wires of the rotor winding 13, so-called switching conductors 20, which lead from the individual winding coils of the rotor winding 13 to the connecting lugs 18, are guided to the connecting lugs 18 using different hooking techniques.
  • the winding coils with so-called winding heads 17, which are configured as coil packs, protrude somewhat beyond an end face 15 of the rotor body 4 facing the commutator 7.
  • the hooking technique for example, is to be mentioned as the hooking technique, in which each jumper wire 20, starting from the axial groove 11 of the rotor body 4, does not lie opposite that of a winding coil center of the respective winding coil
  • Terminal lug 18 is guided, but to a circumferential direction by a certain angular distance, which is less than 360 degrees, offset terminal lug 18. But it is also possible to use the side hook winding technology (direct connection), in which a jumper wire 20 starting from the axial groove 11 of the Rotor body 4 is always guided to the terminal lug 18 opposite the center of the winding coil, without there being an angular distance in the circumferential direction. For contacting and fastening the jumper wires 20 to the

  • the rotor winding 13 with the Rotor winding wires 14 can be made by winding the rotor body 4 using a single wire. But it is also possible to manufacture the rotor winding 13 by winding two wires together as a so-called H winding, so that, for. B. two jumper wire ends 20 to the remaining remaining lugs 18 and firmly connected.
  • the jumper wires 20 running in the area between the rotor body 4 with its winding heads 17 and the connecting lugs 18 must be fixed in their position so that no winding breaks occur in the rotor winding 13 during operation and in particular during the demanding, shaking test for electric motors used in vehicle construction. Furthermore, this fixation is intended to counteract the centrifugal forces at higher speeds of the rotor 1.
  • the jumper wire 20 for this terminal lug 18 in the region between the winding head 17 projecting somewhat above the rotor body 4 and the commutator 7 is at least once around the connecting lugs 18 are guided around the jumper wires 20, after which only the terminal lug 18 which is ultimately remaining is then hooked on.
  • This additional winding 22 of the jumper wires 20 is provided at least once around the rotor shaft 9, so that this additional wire loop runs around the jumper wires 20 with at least 360 degrees in the circumferential direction around the rotor shaft 9.
  • This additional winding 22 of the jumper wires 20 can preferably be carried out several times around the rotor shaft 9, for.
  • the additional winding around the jumper wires 20 can be used for both single and double winding.
  • the rotor winding wires 14 have an insulating layer in a known manner.
  • this insulating layer can also be covered by a so-called baked enamel, which causes the individual wires 14, 20, 22 to bake together when the current flows in the wires 14, 20, 22.
  • the power supply to the wires 14, 20, 22 is provided after the additional winding 22 of the jumper wires 20, so that the jumper wires 20 are further stiffened by the baking by means of the baking varnish.
  • the baking is an irreversible hardening process of the baked enamel, which leads to a firm connection of the wires 14, 20, 22, which remains stable even when heated later.
  • the additional winding of the jumper wires 20 according to the invention is preferably used in commutators 7 with the winding of the terminal lugs 18.
  • a combination of the additional winding of the jumper wires 20 according to the invention with so-called side hook winding technology is also conceivable

Abstract

Avec les rotors connus pour moteurs électriques, il existe un risque de rupture des fils d'enroulement rotorique, en raison du tremblement. Le rotor (1) pour moteur électrique, mis au point selon l'invention, comporte un commutateur (7), un arbre rotorique (9) avec un enroulement rotorique (13), logé dans un corps rotorique monté bloqué en rotation sur l'arbre rotorique (9). Le commutateur (7) comporte dans le sens périphérique, des lamelles (16) s'étendant les unes à côté des autres avec une fente d'isolation. Ces lamelles comportent des barrettes (18) pour raccorder des fils de connexion (20) de l'enroulement rotorique (13). Dans la zone située entre le commutateur (7) et le corps rotorique (4), il est prévu un enroulement supplémentaire (22) autour duquel sont passés les fils de connexion (20) en vue de leur fixation et de leur stabilisation. Ce rotor est prévu pour des moteurs électriques utilisés dans le domaine de la construction automobile.
