Abstract

The synchronous motor is of the relatively slow speed type, with a large number of poles, employed in the direct drive of timing devices, counters, and recording apparatus. The elimination of ferromagnetic coupling between stator and rotor reduces noise and vibration. A meander type winding on a printed circuit strip is used. On a strip of insulating material (4) the windings (3, 3a) are printed, typically one or each side, with the required number of poles. The disc rotor (1) has a corresponding number of permanent magnet poles on its periphery (2). The stator windings are typically 90 deg. apart electrically to give facilities for reversal and predetermined direction of rotation.

Description

Synchronmotor Die Erfindung betrifft einen Synchronmotor mit möglichst hoher Polzahl.Synchronous motor The invention relates to a synchronous motor with as possible high number of poles.

Derartige Motoren werden u. a. fUr Zeltmeßgeräte, Schaltuhren und Betriebsstundenzähler, aber auch für den Antrleb von Plattensptelern und Magnetbandgeräten benötigt.Such motors are inter alia. For tent measuring devices, time switches and Operating hours counter, but also for driving disk recorders and magnetic tape recorders needed.

Bel den bekannten Synchronmotoren besteht die Statorwicklung aus einer Rlngspule, die von zwei weichmagnetischen Blechschalen umgeben ist. Aus beiden Schalen sind Streifen ausgestanzt und nach innen gebogen.Sie bilden am Innendurchmesser der Rtngspule ein ferrnmagnetisches Pol system. Der Rotor besteht aus einem permanentmagnetischen Polsystem. Das Drehfeld wird entweder nach dem Spaltpolprinzip erzeugt, oder mittels eines weiteren Motorsystems, das s starr mit dem ersten verbunden ist, aber dessen Magnetpole in ihrer Phasen lage gegenüber dem ersten Motor um 90 versetzt angeordnet sind. Die Drehfelderzeugung mit einem zweiten Motorsystem verbessert den Wirkungsgrad und ermöglicht eine elektrische gesteuerte Drehrichtungsumkehr.Bel the known synchronous motors, the stator winding consists of one Round coil, which is surrounded by two soft magnetic sheet metal shells. From both bowls Stripes are punched out and bent inwards, forming on the inside diameter The ring coil has a ferromagnetic pole system. The rotor consists of a permanent magnet Pole system. The rotating field is generated either according to the shaded pole principle or by means of of another engine system that is rigidly connected to the first, but its Magnetic poles in their phase position with respect to the first motor arranged offset by 90 are. The generation of the rotating field with a second motor system improves the efficiency and enables an electrically controlled reversal of the direction of rotation.

Bei diesen bekannten Ausführungen Ist es nachteilig, daß zwischen dem permanentmagnetischen Rotor und dem ferromagnetischen Polsystem des Stators eine magnetische Fesselung besteht, die den Wirkungsgrad verschlechtert und zu ungleichförmigen Lauf, Geräuschen und Vibrationen führt.In these known designs, it is disadvantageous that between the permanent magnet rotor and the ferromagnetic pole system of the stator a magnetic bond exists, which worsens the efficiency and becomes uneven Running, noise and vibrations.

Außerdem ist es nachteilig, daß aus mechanischen Gründen die Polzahl relativ niedrig ist, und Insbesondere bei der Ausführung mit zwei Motoren der Aufwand erheblich ist, Es ist deshalb Aufgabe der Erfindung einen Synchronmotor zu schaffen, der mit einfachen und wirtschaftlichen Mitteln eine hohe Polzahl ermöglicht und keine magnetische Fesselung aufwelst.It is also disadvantageous that, for mechanical reasons, the number of poles is relatively low, and especially when using two motors the effort It is therefore an object of the invention to create a synchronous motor, which enables a high number of poles with simple and economical means and no magnetic bondage.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß tanr Antrleb Rotors eine Spule mit mäanderförmiger 'Wicklung verwendet wird.This object is achieved according to the invention in that tanr drives Rotor a coil with a meandering 'winding is used.

Zur Drehfelderzeugung und Drehrichtungssteuerung wird erfindungsgemäß vorgeschlagen eine zweite Spule mit mäanderförmiger Wicklung vorzusehen, die gegenüber der ersten Spule in ihrer Phasenlage, z. B. um 90 verschoben ist.According to the invention, the generation of the rotating field and the control of the direction of rotation proposed a second coil with a meander winding to provide the opposite the first coil in its phase position, e.g. B. is shifted by 90.

Erfindungsgemäß ist es besonders vorteilhaft beide Spulen auf einem zweiseitig mit leitender Folie kaschiertem Trägermaterial in gedruckter Technik herzustellen.According to the invention, it is particularly advantageous to have both coils on one Carrier material laminated on both sides with conductive foil in printed technology to manufacture.

Da das Trägermaterial für die gedruckten Spulen dünn ist, z. B, O,lmn, können auch mehrere Spulen verwendet werden dte in Serie oder parallel geschaltet werden, oder in verschiedener Phasenlage, z. B. 120 , angeordnet sein können.Since the substrate for the printed coils is thin, e.g. B, O, lmn, Several coils can also be used in series or in parallel be, or in different phases, z. B. 120, can be arranged.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß mittels der mäanderförmiger Wicklung eine selbstantrelbende Spule geschaffen tst, die eine hohe Polzahl ermöglicht und keine magnetische Fesselung aufweist. Sie kann mittels der gedruckten Technik in besonders einfacher und wirtschaftlicher Weise hergestellt werden, wobei praktisch ohne Mehraufwand auf dem gleichen Tragermaterial eine zweite Spule erstellt werden kann, mit deren Hilfe ein in der Drehrichtungumsteuerbares Drehfeld erzeugt werden kann.The advantages achieved with the invention are in particular: that by means of the meander-shaped winding a self-winding coil is created tst, which enables a high number of poles and has no magnetic restraint. It can be done in a particularly simple and economical way by means of the printed technology Way to be produced, with practically no additional effort on the same carrier material a second coil can be created, with the help of which one can be reversed in the direction of rotation Rotating field can be generated.
