Autor vynálezu FUTÓ JOZEF ing., KOSICE (54) Rotorový tlmič krokového motoraThe inventor of FUTO JOZEF ing., KOSICE (54) Rotor damper of stepper motor

Vynález sa týká rotorového tlmiča kroko-vého motora, pozostávajúceho z magnetic-kých obvodov, zo zvázkov pleohov s dráž-kami na vonkajšom obvode a z permanent-ných magnetov.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotor damper of a stepper motor, consisting of magnetic circuits, bales with grooves on the outer circumference and permanent magnets.

Takýto rotor sa najčastejšie budí perma-nentným magnetom umiestneným na rotore,jedná sa v podstatě o synchrónny stroj, ktorýpri každej zmene elektromechanických veli-čin, pósobením synchronizačného momentuprechádza do nového rovnovážného stavu itl-meným kmitavým procesom.Such a rotor is most often driven by a permeable magnet disposed on the rotor, it is essentially a synchronous machine, which in each change of the electromechanical variables, by the action of the synchronization moment, moves to a new equilibrium state by a different oscillation process.

Krokovací proces u takéhoto motora móžeprebiehať vo velmi širokom rozsahu, napří-klad od jedného do 40 tisíc krokev za se-kundu, takže pri dvesto krokoch za Otáčkusú otáčky 0,005 až 200 za sekundu, teda 0,3až 12 000 otáčok za minutu. Jedná sa o mimo- riaflne širafrý otáčKový rozsah» Kde v oblastinízkej krokovacej frekvencie prebieha kro-kovací proces formou skoku z jednej polohy do druhej a je doprevádzaný tlmeným ký-váním. V oblasti vyššej krokovacej frekven-cie sa krokovací režim prejavuje kmitánímaž kolísáním momentu. Až v oblasti vysokýchotáčok nastáva ukfudnený chod motora s ne-měnitelnou změnou otáčok v závislosti nabonštantnej frekvencii pulzného napájania.The stepping process of such an engine can run over a very wide range, for example, from one to 40,000 rafters per second, so that at two hundred steps per rotational speed 0.005 to 200 per second, i.e. 0.3 to 12,000 rpm. This is an extraordinarily wide-ranging rotation range. In the low stepping frequency, the stepping process takes place in the form of a jump from one position to another and is accompanied by subdued hitting. In the area of higher stepping frequency, the jogging mode exhibits oscillation with torque variation. Only in the area of high-speed motors is there a stiff running of the engine with a non-variable change of speed depending on the constant frequency of the pulsed power supply.

Pri zvyšovaní a znižovaní otáčok navázujúuvedené javy navzájem a prechádzajú z jed-nej svojej charakteristickej formy do druhej.Tieto uvedené javy sa v súhrne prejavujú ta-kým spósobom, že niektoré typové· velkostikrokových motorov sú v určitých oblastiachnapájacej frekvencie neschopné prevádzky apopřípadě je aj ich točivý moment výraznéstlačený. V tomto případe sa jedná o nepravidelnýa nesprávný chod motora, ktorý sa prejavujehlukom, chvěním, torzným kmitáním a mo-mentovými sedlami. Tieto nepriaznivé vlast-nosti prejavujúce sa pri chodě krokového 216290In increasing and decreasing the revolutions, the phenomena are mutually connected and pass from one of their characteristic forms to the other. These phenomena are summarized in such a way that some type of large-scale motors are inoperative in certain areas of the supply frequency and, if necessary, rotate. moment marked. In this case, this is an irregular and erroneous operation of the engine, which is manifested by noise, vibration, torsional oscillation and torque seats. These unfavorable properties occur during the stepping of stepper 216290
