Description

Izum se odnosi na postupak za proizvodnju namotaja i prigušnice protiv smetnji za elektromotor, pri čemu se najprije uređajem za namotavanje namota namotaj, takvi postupci su od velikog značenja zbog vrlo rasprostranjenog korištenja elektromotora. Proizvodnja namotaja i prigušnice protiv smetnji kod poznatih postupaka vrši se do sada razdvojenim radnim operacijama. Poslije njihove izrade je prigušnica protiv smetnji smještena u za to predviđenom ležištu. Po potrebi se ona ponovno izvadi i stavlja u odgovarajuće putanje za izradu. Poslije toga slijedi ugradnja u elektromotor i sklopno spajanje s namotajem. Takvi poznati postupci su prema tome veoma skupi i osim toga iznose znatni dio proizvodnih troškova elektromotora. Zadatak predmetnog izuma je da se stvori jeftiniji i jednostavniji postupak. The invention relates to a process for the production of coils and anti-interference chokes for an electric motor, whereby the coil is first wound with a winding device, such procedures are of great importance due to the widespread use of electric motors. The production of coils and anti-interference chokes in known processes has been carried out in separate work operations until now. After they are made, the anti-interference choke is placed in the slot provided for it. If necessary, it is taken out again and placed in the appropriate paths for production. This is followed by the installation in the electric motor and the circuit connection with the coil. Such known procedures are therefore very expensive and, in addition, represent a significant part of the production costs of the electric motor. The task of the present invention is to create a cheaper and simpler procedure.

Ovo se prema izumu postiže na taj način, što se u nastavku namotaj sa žicom ili sa drugom žicom spojenom sa njim, predaje dodatnom uređaju za namotavanje i poslije toga namota prigušnica protiv smetnji. Pri tome se može dodatni uređaj za namotavanje ugraditi u pravi uređaj za namotavanje ili ga neposredno spojiti s ovim. Razumije se da je također moguće da se namotaj zajedno sa žicom za prigušnicu protiv smetnji preda uređaju za namotavanje koji se nalazi na drugom mjestu, pri čemu je u svakom slučaju osigurano da namotaj i prigušnica protiv smetnji formiraju praktično jednu jedinicu. Time otpadaju razne radne operacije , a postupak prema izumu je jednostavniji, čime se smanjuju proizvodni troškovi. Osim toga se namotaj i prigušnica protiv smetnji mogu brže izraditi nego kod do sada poznatih postupaka, čime se povećava broj proizvedenih elektromotora u istom vremenskom intervalu u odnosu na raniji broj. According to the invention, this is achieved in such a way that the winding with the wire or with another wire connected to it is then handed over to an additional winding device and after that the anti-interference choke is wound. In this case, the additional winding device can be installed in the actual winding device or directly connected to it. It will be understood that it is also possible for the coil to be fed together with the anti-interference choke wire to a winding device located elsewhere, in each case ensuring that the coil and the anti-interference choke form virtually one unit. This eliminates various work operations, and the procedure according to the invention is simpler, which reduces production costs. In addition, the coil and anti-interference choke can be manufactured more quickly than with previously known processes, thus increasing the number of produced electric motors in the same time interval compared to the previous number.

Daljnje oblikovanje izuma sastoji se u tome, što se za prigušnicu protiv smetnji i za namotaj koristi ista žica bez prekida. Namotaj i prigušnica protiv smetnji mogu se na taj način namotati u jednoj radnoj operaciji i ne zahtijevaju dodatno sklopno spajanje. Jedna varijanta izuma predviđa da se prije namotavanja prigušnice protiv smetnji, međusobno pritegnu, zaleme ili sl., jedan žičani kraj namotaja i jedan žičani kraj prigušnice protiv smetnji Prema tome mogu se koristiti i različite žice za namotaj i za prigušnicu protiv smetnji. Daljnji razvoj izuma sastoji se u tome, što se žica za prigušnicu protiv smetnji prije namotavanja uvodi u pričvršćenje. Pričvršćenje je pogodno da žica ne isklizne kod namotavanja. Korisno se žica za prigušnicu protiv smetnji namota oko jezgre uležištenog na elektromotoru, naročito oko feritnog jezgra. Prigušnica protiv smetnji je dakle već smještena na elektromotoru poslije njezine izrade i nema potrebe za dodatno smještanje. A further development of the invention consists in the fact that the same wire is used for the choke against interference and for the winding without interruption. The winding and the anti-interference choke can thus be wound in one operation and do not require additional circuit connection. One variant of the invention envisages that before winding the anti-interference choke, one wire end of the coil and one wire end of the anti-interference choke are tightened, soldered, etc. Therefore, different wires can be used for the winding and for the anti-interference choke. A further development of the invention consists in the fact that the anti-interference choke wire is introduced into the attachment before winding. The attachment is suitable so that the wire does not slip out when winding. Usefully, the anti-interference choke wire is wound around the core mounted on the electric motor, especially around the ferrite core. The silencer against interference is therefore already placed on the electric motor after its manufacture and there is no need for additional placement.

Izum se osim toga odnosi na elektromotor s jednim namotajem i s najmanje jednom prigušnicom protiv smetnji koja je spojena sa njim, proizvedenim postupkom prema izumu, pri čemu se namotaj i prigušnica protiv smetnji sastoje od iste neprekidne žice. Takvi su elektromotori svojom proizvodnjom jeftiniji od do sada poznatih. The invention further relates to an electric motor with a single winding and at least one anti-interference choke connected thereto, produced by the method of the invention, wherein the winding and the anti-interference choke consist of the same continuous wire. The production of such electric motors is cheaper than the ones known so far.

Korisno se dionica žice između namotaja i prigušnice protiv smetnji, blokira u pričvršćenju smještenom na elektromotoru. Pričvršćenje je izvedeno u vidu ureza, pri čemu urez na svom otvorenom kraju ima ljevkasto proširenje. Na taj način se žica od uređaja za namotavanje može na jednostavan način da uvede u pričvršćenje. Usefully, the wire section between the coil and the anti-interference choke is blocked in the attachment located on the electric motor. The attachment is made in the form of a notch, where the notch has a funnel-shaped extension at its open end. In this way, the wire from the winding device can be introduced into the attachment in a simple way.

Izum se dalje detaljnije objašnjava na bazi nacrta. The invention is further explained in more detail on the basis of drawings.
