Definitions

  • the invention relates to a rotating field motor, in particular for use in motor vehicles, according to the preamble of claim 1.
  • a rotor is rotatably mounted in a stator.
  • the rotor has a number of poles.
  • the stator has a stator lamination stack with a number of slots and webs, a loop winding with a plurality of winding strands being arranged in the slots.
  • an electric motor If an electric motor is to be operated with a low voltage, which, for example, is generally less than 12 volts when used in a motor vehicle, the electric motor must be able to cope with high currents. This requires a very small motor resistance, i. that is, the windings must be designed with low resistance. Therefore either very thick wires or a lot of wires connected in parallel must be used. The manufacture of such a winding is therefore very difficult and expensive.
  • the invention has for its object to provide a rotary field motor, the winding of which is easier and cheaper to manufacture.
  • the relationship between construction volume and performance should be improved.
  • the rotating field motor characterized in claim 1.
  • the ratio of the number of slots and lands of the stator to the number of poles of the rotor is set at 3: 2.
  • Each winding strand of the loop winding is arranged in several turns around a web of the stator core in two adjacent slots.
  • the winding strands are made of flat wire.
  • Flat wire can be used.
  • the use of flat wire was not possible with conventional loop windings because the large number of crossovers, on the one hand, could not be achieved economically due to the large number of complicated bending processes and, on the other hand, could not be accommodated in an acceptable installation space.
  • each winding strand consists of two parts which are arranged radially one above the other around the web. If parts of the winding strands lying radially one above the other are then wound in opposite directions, the respective inner winding ends can be connected to one another in a simple manner with the same electrical current flow, or the two parts of the winding strands can be produced from a continuous flat wire. The flat wire is folded twice to connect the inner winding ends.
  • the webs are designed such that they have a rectangular cross section, as seen perpendicular to the axis of the stator, then grooves with a trapezoidal cross section are formed between the webs. If these grooves are filled in such a way that the winding strand around a web consists of two parts with the same dimensions in the tangential direction of the stator laminated core and the winding strand of the adjacent web consists of two parts, of which the radially outer one has a larger dimension in the tangential direction of the stator laminated core has as the radially inner part, a particularly good degree of filling is achieved in that two adjacent winding strands almost completely fill the free cross section of the jointly filled groove.
  • each winding strand is composed of two parts gives the additional advantageous possibility of leading out the two connection ends of a winding strand on one side of the stator lamination stack. As a result, both ends of a winding strand are accessible from the outside.

  • the stator 1 also includes a loop winding with a plurality of winding strands 7 and 8.
  • the winding strands 7 and 8 consist of flat wire. Each winding strand 7 or 8 is wound around a web 5, so that its turns are each in a groove 6, which is adjacent to the web 5.

  • winding strand 7 and 8 consists of several parts which are arranged radially one above the other. From the further description it is clear that it is advantageous if a winding strand 7 or 8 consists of an even number of parts.

  • the winding strand 7 consists of two parts 10 with the same dimensions, in particular in the tangential direction of the stator core 4.

  • the dimensions of the two identical parts 10 of the winding strand 7 are expediently equal in their dimensions to the radially inner part 11 of the winding strand 8. If a winding strand 7 with identical parts 10 and a winding strand 8 with dissimilar parts 11 and 12 are alternately arranged side by side, the grooves 6 are almost completely filled.
  • the different dimensions of the two parts 11 and 12 are achieved in that, with the same wire cross section for both parts, the radially outer part is produced with a correspondingly larger number of turns.

Le stator (1) comprend un empilage de tôles (4) de stator ayant une pluralité de rainures (6) et de protubérances (5). Le rapport entre les rainures (6) et les protubérances (5) du stator (1) d'une part et le nombre de pôles (3) du rotor (2) d'autre part est égal à 3:2. Chaque section d'enroulement (7, 8) d'un enroulement imbriqué est enroulée plusieurs fois autour d'une protubérance (5), étant agencée dans deux rainures (6) adjacentes à la protubérance de l'empilage des tôles (4), et comprend deux parties (10, 11, 12) radialement superposées sur la protubérance (5).
