Opfindelsen vedrører en synkronmotor med en feltopbygning, en rotor, en magnetiseringsspole og en spolebeskyttelse, som i det væsentlige omslutter spolen til mekanisk og elektrisk beskyttelse af den.The invention relates to a synchronous motor having a field structure, a rotor, a magnet coil and a coil protection which essentially encloses the coil for mechanical and electrical protection thereof.

Der anvendes små permanent-magnetiske synkronmotorer mange steder, f.eks. som tidsstyreenheder i apparater, såsom vaskemaskiner, tørremaskiner, komfurer osv. Motorer af denne art har elektrisk aktiveret trådspoler, som er viklet omkring kerner til tilvejebringelse af det elektromagnetiske felt omkring en permanent-magnetisk rotor.Small permanent magnetic synchronous motors are used in many places, e.g. such as time controllers in appliances such as washing machines, dryers, stoves, etc. Engines of this kind have electrically activated wire coils wound around cores to provide the electromagnetic field around a permanent magnetic rotor.

Spoletråden skal beskyttes mod mekanisk overlast og skal være elektrisk isoleret fra den øvrige del af motoren.The coil wire must be protected against mechanical overload and must be electrically insulated from the rest of the motor.

/ 2 141227/ 2 141227

Der kendes flere spolebeskyttelser af forskellige materialer og forskellige udformninger. De fleste beskyttelser udgøres af bånd, som både er vanskeligt og kostbart at vikle omkring spolerne. Nogle spolebeskyttelser består af et enkelt, cylindrisk kartonrør. Disse har den ulempe, at de kan falde af spolen, medens denne samles, eller kan rystes løse på grund af motorvibrationen.Several coil protectors of different materials and different designs are known. Most protections consist of tapes that are both difficult and expensive to wrap around the coils. Some coil protectors consist of a single, cylindrical cardboard tube. These have the disadvantage that they can fall off the coil while being assembled or can be shaken loose due to the motor vibration.

Formålet med opfindelsen er at angive en spole, som ikke udviser de ovenfor nævnte ulemper.The object of the invention is to provide a coil which does not show the disadvantages mentioned above.

Dette formål opnås ved, at spolebeskyttelsen er tilvejebragt som angivet i kravets kendetegnende del. Når spolebeskytteren presses på plads deformeres den ene endeflange elastisk, hvorefter den antager sin oprindelige form, når den kommer fri af ribbernes nævnte ene endekant, som derefter forhindrer, at spolebeskytteren kan trækkes ud igen.This object is achieved by providing the coil protection as indicated in the characterizing part of the claim. When the bobbin protector is pressed into place, one end flange is elastically deformed and then assumes its original shape when released from said one end edge of the ribs, which then prevents the bobbin protector from being pulled out again.

Opfindelsen vil i det følgende blive nærmere forklaret ved beskrivelsen af en udførelsesform, idet der henvises til tegningen, hvor fig. 1 viser en udførelsesform for motoren ifølge opfindelsen, fig. 2 et snit gennem den i fig. 1 viste motor, fig. 3 i perspektiv spolebeskyttelsen og motorens trådspole i adskilt tilstand, medens fig. 4 viser et tværsnit langs den i fig. 2 viste linie 4-4.The invention will be explained in more detail below in the description of an embodiment, with reference to the drawing, in which fig. 1 shows an embodiment of the motor according to the invention; FIG. 2 is a section through the one of FIG. 1; FIG. 3 is a perspective view of the coil guard and the motor wire coil in separate condition, while FIG. 4 is a cross-sectional view along the line of FIG. 2 is 4-4.
