Definitions
- the invention relates to a winding arrangement for a 2-strand Drehfeldmaschi- ne and a 2-strand induction machine with such a winding arrangement.
- PM synchronous machines Inverter-fed permanent magnet synchronous machines (PM synchronous machines) are used in a large number of technical applications. For reasons of cost PM synchronous machines are increasingly running with so-called tooth coil windings.
- the tooth-spool technology simplifies the post construction of a PM-synchronous machine and also enables a segmented post structure, so that the post can be manufactured modularly in a kind of modular concept.
- a disadvantage of tooth coil windings is that they form a wide air gap field spectrum, which can be more or less disturbing depending on the engine design.
- z. B. small PM synchronous motors that are field-oriented to the inverter operated and increasingly come in the field of high-speed drives used, basically in dental coil technology.
- a basic idea of the present invention is to provide a tooth coil winding with a specific winding scheme for two strands with preferably two winding layers consisting of coil groups with multiply interleaved coils and preferably continuously changing width, wherein the partial coils of said coil groups from inside to outside (without crossing the conductors of the partial coils) are arranged concentrically enclosing, one or more teeth and have same or different Spulenwindungstrade at a substantially equal occupancy each of the groove with the same effective Automatleiterquerrough per groove cross-section.
- the coil groups are arranged diametrically symmetrical to each other and partially overlap spatially along the circumference in their arrangement in the winding layers.
- a two-phase induction machine with a 2p-pole stator with winding teeth formed with a winding arrangement in dental coil technology, comprising two winding strands W1, W2, wherein the winding arrangement is formed from wound coil groups with multiply interleaved coils (partial coils), wherein the sub-coils of said coil groups are arranged concentrically surrounding from the inside to the outside and two or more winding teeth, wherein the respective coil winding numbers are provided or wound in the grooves between the winding teeth, that in each case a substantially equal occupancy of each groove with the same effective overall cross-section of the coil is given per groove cross-section.
- the coil groups do not overlap in the forehead area, ie are designed without intersecting conductors, intersecting partial coils or coil groups.
- the stated object can thus be achieved by a 2-stranded "multi-tooth coil winding", which also represents a distributed tooth coil winding.
- the basic element and the constant part of such a 2-stranded multi Zahnspu- lenwicklung is a q times the tooth coil 2 * q adjacent grooves of the stator per wells half occupied (in the topsheet or the backsheet).
- the number of conductors of a further outer sub-coil of a coil group is higher or greater than the number of conductors of the inner part of the coil concentrically surrounded by this further outer coil.
- the number of conductors of the partial coils decreases from the outer to the inner partial coil.
- the number of conductors of the sub-coils steadily decreases from the outer to the inner sub-coil, so to speak, from the assumption of the number of conductors from sub-coil to sub-coil decreases in the same steps.
- the value Zo represents a predetermined number of conductors in said sub-coil
- DZ represents the difference in the number of conductors to the respective outer or inner sub-coil.
- Fig. 2 is a strand zone plan of a 2-pole, 2-stranded dental coils
- Fig. 5 shows an alternative embodiment of a zone plan to Fig. 4 with below
- Each winding strand W1, W2 consists, according to FIG. 2, of two multi-tooth coils, which can either be located either in the lower layer US or in the upper layer OS, wherein the winding strand is located in FIG. 2 in the US.
- the two multi-tooth coils of a winding strand are exactly offset by one pole pitch, ie by N / 2p slot pitches (where 2p is the pole number) offset from each other, in the mentioned embodiment by 2q slot pitches, and are thus arranged diametrically symmetrical.
- N / 2p slot pitches where 2p is the pole number
- 2q slot pitches 2q slot pitches
- Winding reduction via the laminated core of the stator Furthermore, a smaller copper volume of the partial coils allows a simplification in the winding process.
- the two winding strands W1, W2 of the 2-pole rotating field winding according to Figure 3, are against each other by N / 4p groove pitches offset, which corresponds to q slot pitches in the embodiment.
- the number of conductors of the partial coils T of a coil group G is then distributed as follows: a. the outermost sub-coil T: Zo conductor + D Z conductor b. the middle part coil T: Zo conductor c. the inner part coil T: Zo conductor - D Z conductor.
- the resulting rotating field winding remains symmetrical, but the stator slots do not have a uniform slot filling.
- the partial coils T of a multi-tooth coil winding with different winding wire diameters can be executed.
- Flier notebook can increase the copper volume and groove filling and make the effective overall conductor cross-section across all grooves still largely uniform.
- the partial coils T of a multi-tooth coil winding can be formed with the same winding wire diameters, but of x coils connected in parallel with x-fold turns, in order to raise and unify the groove fill level.
- FIG. 6 shows two possibilities for a line separation, which lead to an identical slot filling in the case of the complete 2-phase rotating field winding in all stator slots.
- Za denotes the higher number of conductors of the outer partial coils T and Zi the lower number of conductors of the inner partial coils T
- the toothed coils 3-4, 7-8, 11-12 and 15-16 are located in the respective other winding position US or OS.
- This has the advantage that a very compact winding head structure is possible.
- the opposing partial coils T with a smaller number of turns can be designed to be identical to the slot filling with different winding wire diameter or with a larger number of conductors and in parallel connection in parallel.
- the width of the winding tooth Z which is encompassed by the inner partial coils T of the multi-tooth coil winding, can also be reduced in relation to the adjacent wedge teeth.
- the solid vertical double lines in the zone plan are to be understood as wide winding teeth Zb, the dashed ones as winding teeth Zs with reduced width.
- this embodiment eliminates the middle part coil of the multi-tooth coil. The result is an incomplete multi-tooth coil winding.
