Definitions

  • the invention relates to a three-phase motor having a rotor and a stator, each having one or more parallel-connected coils strands of the stator, wherein the coils of different strands are arranged alternately to each other.
  • Such three-phase motors are often produced in large series and are known in practice.
  • the stators of the three-phase motors known from practice are produced as so-called distributed winding or as single-tooth coils.
  • the wiring of the coils is usually done by hand or by Einziehtechnik.
  • Einziehtechnik This leads, in particular in large series, to a great production outlay.
  • To simplify the interconnection ring segments or contact bridges are therefore known. Nevertheless, the production of the known three-phase motors requires a great deal of effort.
  • the invention is based on the problem to design a three-phase motor of the type mentioned so that it is particularly easy to manufacture in particular in a large series.
  • the coils each have a plurality of contact holders, that in the contact holders in each case a contact rail is arranged and that the contact rails have means for contacting with terminals of the coils.
  • the coils are each assigned contact holders with contact rails. This can be the
  • the coils and the contact holders can be as pre-assemble easy-to-manufacture common parts and assemble them to the stator.
  • the production of the three-phase motor according to the invention is particularly simple, especially in mass production.
  • the coils are so-called single-tooth coils with their own coil cores.
  • the interconnection of the coils is particularly simple when a total of four contact bars are provided in the star connection of the strands, each of the strands having a single contact rail, if the contact bars connected to the strands have first terminals of the coils are connected and when one of the contact rails connects all the second terminals of the coil.
  • the terminals of the coils and the contact rails are preferably welded.
  • Coils molded plastic is designed as a contact holder.
  • the reliable alignment of the contact rails on the coils also has the advantage that the contact rails can be arranged particularly close to each other and thus the three-phase motor according to the invention is constructed particularly compact. An automated interconnection of the coils is thus process reliable.
  • the terminals of the coils are also fixed in the plastic.
  • the contact rails can be particularly easy to assemble according to another advantageous embodiment of the invention, when the contact holder groove-shaped and the contact rails are designed annular. Another advantage of this design is that the contact rails are reliably mechanically fixed to each of the coils.
  • the production of the contact rails as a closed ring also has the advantage of high mechanical stability of the contact rail on. However, an open ring can be produced particularly easily in the stamping process.
  • the contacting of the individual coils of the three-phase motor according to the invention is particularly simple if the terminals of the coils are arranged parallel to the axis of the rotor and the groove-shaped contact holder are designed to be open in the axial direction of the rotor. This also leads to further reduction of the dimensions of the inventive three-phase motor.
  • the three-phase motor according to the invention is structurally particularly simple if the ring-shaped contact rails surround each other concentrically.
  • the proposed interconnection of the coils is particularly simple according to an advantageous embodiment of the invention, when the means for contacting the contact rails with the terminals of the coils have contact tongues.
  • the contact tongues of the individual contact rails thereby advantageously overlap the contact rails.
  • the contact tongues of adjacent contact rails are offset from each other, since only every third of the coils must be connected to the same strand.
  • the contact tongues are preferably punched in one piece with the contact rails made of copper and then bent into the intended shape.
  • the stator is composed of a large number of equal parts when the coils are each constructed the same and form a structural unit with the contact holders.

  • Fig. Ia schematically shows the three-phase motor in one
  • FIG 4 shows the stator of the three-phase motor according to the invention during assembly.
  • Figure 1 shows a circuit diagram with coils 1 - 24 of a stator 25 of a three-phase motor schematically shown in Figure Ia.
  • the three-phase motor has three strings U, V, W in a star connection, with eight coils 1 - 24 connected in parallel being provided per string U, V, W in this exemplary embodiment.
  • the stator 25 thus has 24 coils.
  • the stator 25 is shown cut in Figure Ia and encloses a rotatably mounted rotor 26th
  • Figure 2 shows the interconnection of the coils 1 - 24 by means of contact rails 27 - 30 and the interconnection of the coils 1 - 24 with each other.
  • the order of the coils 1 - 24 in Figure 2 corresponds to their actual arrangement in the stator 25. Since only two parallel-connected coils 1 - 24 are used according to the illustrated embodiment of the three-phase motor, the stator 25 has a total of four contact rails 27 - 30, which via Contact tongues 31 with terminals 32, 33 of the coils 1 - 24 are connected.
  • the strands U, V, W each have a contact rail 27-29, which are connected to provided first terminals 32 of the coils 1-24.
  • the fourth contact rail 30 is with all second terminals 33 of the coils 1 - 24 connected and forms the neutral point.
  • Figure 3 shows one of the coils 1 - 24 with the terminals 32, 33 and with contact holders 34 - 37 for the contact rails 27 - 30 of Figure 2.
  • the contact holder 34 - 37 are designed groove-shaped. Thus, the contact rails 27 - 30 can be easily inserted into the contact holder 34 - 37 and connect the contact tongues 38 with the terminals 32, 33.

Abstract

Un moteur à courant triphasé à phases (U, V, W) d'un stator (25) comprenant une pluralité de bobines (1 - 24) montées en parallèle, présente des rails de contact (27 - 30) de forme annulaire, destinées à assurer le contact des bobines (1 - 24). Les bobines (1 - 24) sont réalisées chacune en tant qu'unité structurelle et présentent des supports de contact (34 - 37) en forme de rainure. Les supports de contact (34 - 37) sont fabriqués en matière plastique et moulés par injection sur les bobines (1 - 24). L'invention permet ainsi de réaliser de manière particulièrement simple le contact des bobines (1 - 24) et le montage du moteur à courant triphasé.
