Definitions
- the invention relates to a winding arrangement for a 3-strand rotating field machine, which is designed as a distributed single-layer tooth coil winding.
- Converter-fed permanent magnet synchronous machines are used in a variety of technical applications.
- PM synchronous machines are increasingly being equipped with so-called toothed coil windings.
- the tooth coil technology simplifies the stator structure of a PM synchronous machine and also enables a segmented stator structure, so that the stator can be manufactured in modules in a kind of modular concept.
- the disadvantage of toothed coil windings is that they form a wide air gap field spectrum which, depending on the motor design, can be more or less disruptive and are more likely to be used with higher numbers of poles.
- US 20120001512 A1 proposes a stator with a double number of slots compared to the prior art.
- the coils each enclose two teeth.
- the coils are characterized by different numbers of turns with the same coil width.
- the two disclosures DE 20 2017 107387 U1 and DE 20 2017 107388 U1 describe so-called multi-toothed coil windings of the number of strands 2 and 3 consisting of several concentrically interleaved toothed coils, which, however, have a relatively small winding factor and two separate winding layers, namely a lower layer and an upper layer are marked.
- the double or multi-tooth coil windings known from the prior art are therefore always multi-layer windings with at least one lower and one upper layer. This results in significant disadvantages, in particular in the case of motors of small size, which consist in the fact that, on the one hand, the introduction of the winding layers is complex and, furthermore, these windings are to be insulated from one another by additional measures. This has a negative impact on the degree of groove filling, which in turn has a negative impact on costs.
- toothed coil winding with low number of poles. Since toothed coil windings tend to have a higher number of pole pairs, PM synchronous motors with a low number of poles (eg 2-pole or 4-pole) for high-speed drives with the known toothed coil windings can only be realized to a very limited extent.
- a basic idea of the present invention is to develop a toothed coil winding with a specific winding scheme for three winding strands W1, W2,
- the technical problem described above can therefore be solved by a distributed single-layer tooth coil winding which has a 3-zone winding structure.
- the proposed rotating field winding consists of repeating winding units, each comprising two pole pitches with respect to the number of basic pole pairs p.
- the winding arrangement ensures that the air gap field spectrum at the rotating field pole pair number
- a field harmonic with v / p F 1 is accordingly used for torque generation and for driving the rotor, unlike in the prior art via the field fundamental wave.
- the distributed single-layer toothed coil winding according to the invention accordingly has the following advantages over the prior art: a) simpler winding structure
- the upper example there are 12 slots, in the middle example 18 slots and in the lower example 24 slots, which are wound with a winding arrangement using distributed single-layer spool technology, comprising three winding strands W1, W2,
