摘要：the invention relates to a device for gleichlaufverbesserung theumlaufbewegung (2a) of the rotor in a ger\ätegeh\äuse (l) arrangedeinphasen\­synchronmotors (2), in which the mean value of the

dreh\­momentes strong wechselmomente are overlaid and a preferably umlaufende load drives.the total load is a small household appliance, such as azitrus\­presse, a messerschleifer or a trockenrasierapparat with circulatingschneidmessern,.the device is designed so that the rotor (2a), an additional, outside ofasia ausgleichsdrehmoment last\übertragungsweges provided by the

elektromecha\­nischen wechselmomenten of the engine (2) with a preset counter,preferably positive dre hrichtung the rotor (2a), with the positive direction of rotation isthe onein the current on the rotor (2a)) torque zero and afterwards at a small angle tothe stromlosen statorspulen (4d) existing magnetic klebemoment zero and then in thatposition to a stable position of the rotor, while the en tgegengesetzte reversedreh\­richtung is locked.the block with the aid of a slipping locks (41).
