Description
Elektromagnetische Geschwindigkeitsdämpfung für Hub- oder Drehmagnete Hub- und Drehmagnete weisen ein für viele Anwendungszwecke recht ungünstiges Geschwindigkeits-Weg-Verhalten auf. Da die Beschleunigungen ungefähr konstant sind, treten am Ende der Hub- oder Drehbewegung relativ hohe Geschwindigkeiten auf. Es ist zwar möglich, diese Geschwindigkeiten durch geeignete Formgebung des Magnetsystems zu verringern, jedoch muß dabei auch eine Kraftverringerung in Kauf genommen werden, die wiederum unverändert ist.Electromagnetic speed damping for lifting or rotary magnets Lifting and rotary magnets have a very unfavorable speed-path behavior for many applications on. Since the accelerations are roughly constant, at the end of the stroke or Rotational movement at relatively high speeds. While it is possible these speeds to reduce by appropriate shaping of the magnet system, but must also a reduction in force must be accepted, which in turn is unchanged.
Es sind auch schon Dämpfungseinrichtungen für Meßgeräte bekannt (DP 892 388), bei denen die Dämpfung durch einen mit dem zu dämpfenden Geräteglied gekuppelten elektrischen oder elektromagnetischen Krafterzeuger in Abhängigkeit von der zeitlichen Änderung der den Meßwert darstellenden elektrischen Größe bewirkt wird.Damping devices for measuring devices are also known (DP 892 388), in which the damping is coupled to the device element to be damped electrical or electromagnetic power generator depending on the time Change in the electrical quantity representing the measured value is effected.
Auch ist eine elektromagnetische Induktionsdämpfung für Drehmagnet-Meßgeräte bekanntgeworden (deutsche Patentanmeldung B 22 989), bei der der Drehmagnet "innerhalb einer geschlossenen Spule schwingt.There is also electromagnetic induction damping for rotary magnet measuring devices became known (German patent application B 22 989), in which the rotary magnet "within one closed Coil swings.
Auch diese bekannten Anordnungen beeinflussen jedoch die Anzugskraft bzw. das Drehmoment nachteilig.However, these known arrangements also influence the tightening force or the torque disadvantageous.
Hinzu kommt, daß es mitunter erwünscht ist, den Dämpfungsgrad zu verändern und damit die Geschwindigkeit der Ankerbewegung zu beeinflussen.In addition, it is sometimes desirable to change the degree of damping and thus to influence the speed of the armature movement.
Diesen Vorteil bietet bei gleichzeitiger Vermeidung der den bekannten Anordnungen anhaftenden Nachteile die erfindungsgemäße Dämpfung, die dadurch gekennzeichnet ist, daß der Magnet außer einer ersten Arbeitswicklung eine zweite Wicklung aufweist und der Antr mit einem Dauermagneten mechanisch verbunden ist, in dessen Wirkungsbereich eine Spule angeordnet ist, deren der Magnetbewegungs-Geschwindigkeit proportionale Spannung nach Verstärkung der genannten zweiten Wicklung des Magneten dämpfend zugeführt ist.This advantage offers while avoiding the known Arrangements inherent disadvantages the damping according to the invention, which is characterized is that the magnet has a second winding in addition to a first working winding and the drive is mechanically connected to a permanent magnet in its area of action a coil is arranged, the speed of which is proportional to the magnet movement Voltage after amplification of said second winding of the magnet is supplied in a damping manner is.
An Hand der Zeichnung wird die Erfindung näher beschrieben. Darin zeigen: Fig. l den prinzipiellen Aufbau der erfindungsgemäßen Dämpfung, Fig. 2 das Drehwinkel-Zeit-Verhalten eines ungedämpften (a) und eines gedämpften (b) Drehmagneten, Fig. 3 das Drehwinkel-Drehgeschwindigkeits-Verhalten eines ungedämpften (a) und eines gedämpften (b) Drehmagneten. Auf der Achse 1 eines doppeltwirkenden Hubmagneten 2 ist ein Dauermagnet 3 befestigt. Wird der Schalter 4 geschlossen, so bringt die Wicklung 2a des Magneten 2 den Anker und damit den Dauermagneten 3 in Bewegung. In der diesem Dauermagneten 3 zugeordneten Spule 5 wird dabei eine der Geschwindigkeit des Dauermagneten 3 proportionale Spannung induziert.The invention is described in more detail with reference to the drawing. In which: Figure l shows the basic structure of the damping according to the invention, Figure 2 shows the rotation angle-time behavior of an undamped (a) and a cushioned (b) the rotary magnet, Figure 3 shows the rotation angle rotation speed behavior of an undamped (a), and... a damped (b) rotary magnet. A permanent magnet 3 is attached to the axis 1 of a double-acting lifting magnet 2. If the switch 4 is closed, the winding 2a of the magnet 2 brings the armature and thus the permanent magnet 3 in motion. In the coil 5 assigned to this permanent magnet 3, a voltage proportional to the speed of the permanent magnet 3 is induced.
Diese Spannung wird in dem Verstärker 6 verstärkt und sodann der zweiten Wicklung 2b des Magneten 2 zugeführt.This voltage is amplified in the amplifier 6 and then the second Winding 2b of the magnet 2 is supplied.
Eine Veränderung der Ankergeschwindigkeit läßt sich leicht und in bekannter Weise durch eine Verstärkungsänderung erzielen.A change of the anchor speed can be easily and in known way to achieve by a gain change.
