Definitions
- the invention relates to a direct drive for large drives with a stator constructed from segments and a rotor constructed from segments.
- Direct drives are coupled directly, ie without the interposition of a gearbox, with working machines.
- motors are used as ring motors, eg in mills.
- Such ring motors are known from US 1 224 933 and US 3 272 444.
- Ring motors are high-pole synchronous-pole motors used for low-speed tube mills.
- the mill body serves the rotor as a hub, the motor is thus arranged annularly around the mill body.
- the axial length of the lamination stack of the stator of the ring motor is obtained, for example, at pre-specified ⁇ utilization from the required torque for the mill.
- stator In diameter at very large ring motors, the stator, viewed in the circumferential direction, is divided into several segments by ⁇ , to be able to accomplish the transport to the plant.
- a ge ⁇ know number of drum coils extends over the respective joints of the abutting segments and thus can be inserted only after assembly on the system ⁇ who.
- hinged coils have been provided so far, which have subsequently been inserted on the system in the grooves of the stator.
- this represents a considerable amount of work and these lobes form through the subsequently made and necessary insulation in the winding head area the weakest link of the winding of the stator.
- the invention has for its object to provide egg nen direct drive for large drives, which can be constructed in simp ⁇ cher manner on the plant without having to make insulation for the winding.
- the object is achieved by a direct drive with a stator constructed from several segments viewed in the circumferential direction, each having a closed winding system, and a rotor constructed from segments whose segments are located on co-rotating working means, and there with the winding system of FIG Stators interact electromagnetically.
- the coil width of the windings of the stator is a slot pitch.
- the winding system of the stator is thus constructed of tooth coils.
- the parting line between each two segments of the direct drive runs exactly in ei ⁇ nem tooth, so that no coils must be separated.
- this is an unwound tooth, so that no coils must be mounted on the system at the destination of the direct drive. This means that the individual segments in the factory can be completely finished and tested. This results in an improved insulation and there ⁇ with increased reliability of these direct drives.
- FIG. 2 shows in principle a ring motor
- FIG. 3 in principle, a winding system according to the invention.
- FIG. 1 shows a conventional winding system of a stator 1 of a ring motor 9, not shown, which for transport reasons has a built-up of segments 3, 4, 5, 6 stator 1.
- the windings marked with * are not inserted in their grooves 7 during transport as they extend over the joints. They are therefore used only at the destination in their respective grooves 7, iso ⁇ liert and optionally checked.
- the ring motor 9 shows a view of a ring motor 9, which is supported on Funda ⁇ elements 13.
- the ring motor 9 has a stator 1, which is shielded by suitable covers from environmental influences, such as dirt, etc., and at the same time serves for air cooling and air guidance of the air flow generated by the individual fans 20, 30, 31.
- the stator 1 is beispielswei ⁇ se divided into four segments 3, 4, 5 and 6 in the circumferential direction.
- a tooth 14 of the laminated core 12 of the stator 1 is divided centrally. Not shown to scale grooves 7 of a segment 3, 4, 5, 6 of the stator 1 are about every second tooth coils, advantageously tooth coils 8, so that there are viewed in the circumferential direction, a sequence of wound teeth 10 and unwound teeth 11 , The centrally divided tooth 14 is unwound.
- the wound teeth 10 are advantageously wider than the unwound teeth 11 and have substantially parallel flanked Nu ⁇ tencolour, so that a mounting of the tooth coils 8 can be made easily from the rotor side.
- the tooth coils 8 are applied to bobbin carriers, which have means to provide a fixation on the tooth 10. Furthermore, means are provided which enable contacting with other toothed coils 8 of the same segment, in particular in the factory or tooth coils 8 of other segments at their destination. Examples of these are especially trained for this circuit ends of Zahnspu ⁇ len 8th
- the fixation on the tooth 10 is done for example by a locking of the bobbin on the tooth 10.
- a fixation of the tooth coils 8 can also be achieved by opposite the toothed tooth widened tooth heads.
- a positive connection which also serves to fix the tooth coil 8.
- each segment 3, 4, 5, 6 has a to ⁇ closed coil assembly and no coils on the system on the joints to are embarrassed.
- Each groove 7 of a segment 3, 4, 5, 6 is thus occupied by at least one coil side of a tooth coil 8.
- the completed winding arrangement can have one or more parts of a phase. That is, the respective tooth coils 8 of a segment 3, 4, 5, 6 are already factory wired so that advantageously only a Kon ⁇ takttechnik between the individual segments 3, 4, 5, 6 and done with one or more inverters at the final site got to. Subsequent isolations of the coils on the system are eliminated, thus significantly reducing the probability of winding failures of the direct drive.
- the number of holes q is about one.
- the number of holes q is, as known per se as the number of slots per pole and phase defi ⁇ ned.
- Tooth coils 8 or coil groups of a segment 3, 4, 5, 6 are either already in the factory or, if it concerns coils or coil groups of different segments on the system.
- the interconnection is carried out either directly on the direct drive or on at least one direct drive ⁇ assigned inverter.
- the known connection types are used for such direct drives.
- a rotor 35 which is also constructed of segments, not shown, with the segment of the rotor usually has four poles on ⁇ . These segments are fastened, for example by means of flanges at one Ar ⁇ beitsstoff example of a mill drum. By elekt ⁇ romagnetician interaction between the stator 1 and rotor 35 is now this working fluid in operation in rotato ⁇ cal movement.
- the outer plate diameter of these currently used in practice stators 1 such ore mills are nine to about eighteen meters.
- the powers delivered are at speeds between 15 min "1 and 9 min " 1 between 10 MW and 30 MW.
- Larger diameters with correspondingly height ⁇ ren services are in the future without further realizable cash. Fewer technical restrictions, but rather the known means of transport and the existing transport routes set limits. Therefore, in larger Radioantrie ⁇ ben the number of segments in the future increase, so the problem that at the joints of the segments 3, 4, 5, 6 will exacerbate without the inventive construction.
- stators 1 of very large direct drives are in this case made up of individual teeth, each with associated toothed coils 8, which mechanically assemble at their destination and whose toothed coils 8 are only to be electrically interconnected.
