Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Reduzierung eines Abschaltimpulses eines in Stufen ansteuerbaren Elektromotors nach der Gattung des unabhängigen Anspruchs.The The invention relates to a device for reducing a turn-off pulse a step-controllable electric motor according to the preamble of the independent claim.
Die
in Kraftfahrzeugen eingesetzten Elektromotoren verursachen oftmals
Störungen,
die insbesondere den Radioempfang beeinträchtigen oder andere elektronische
Fahrzeugkomponenten beeinflussen können. Um diese Störungen zu
vermeiden, werden so genannten Entstörfilter eingesetzt, die zumindest über einen
Kondensator verfügen.
Aus der
Vorteile der ErfindungAdvantages of invention
Gegenüber dem Stand der Technik weist die erfindungsgemäße Vorrichtung zur Reduzierung eines Abschaltimpulses eines in Stufen ansteuerbaren Elektromotors, insbesondere eines elektrischen Scheibenwischermotors eines Kraftfahrzeugs, mit einem ersten gemeinsamen Anschluss sowie mit zumindest einem weiteren getrennten Anschluss für jede der Stufen des Elektromotors, wobei zwischen dem ersten gemeinsamen Anschluss und den weiteren getrennten Anschlüssen jeweils zumindest ein Kondensator liegt, den Vorteil auf, dass den Kondensatoren zwischen dem ersten gemeinsamen Anschluss und den weiteren getrennten Anschlüssen jeweils eine Halbleiterdiode oder eine Zenerdiode derart parallel geschaltet ist, dass ihre Anode an dem ersten Anschluss und ihre Kathode an dem weiteren Anschluss liegt, wobei die Kondensatoren und die dazu parallel geschalteten Halbleiter- oder Zenerdioden in einem gemeinsamen Kombielement zum Anschluss an den Elektromotor integriert sind. Auf diese Weise ist gewährleistet, dass mit dem Elektromotor in elektrischer Verbindung stehende Komponenten vor einer durch das Ab- oder Umschalten des Elektromotors hervorgerufenen Überspannung geschützt sind. Weiterhin führt die Integration der Kondensatoren und der Halbleiter- bzw. Zenerdioden in ein Kombielement zu einer deutlichen Kostenersparnis gegenüber proprietären Vorrichtungen.Compared to the Prior art has the inventive device for reduction a switch-off pulse of a step-controllable electric motor, in particular an electric windscreen wiper motor of a motor vehicle, with a first common port and with at least one another separate connection for each the stages of the electric motor, being between the first common Connection and the other separate terminals in each case at least one capacitor There is the advantage that the capacitors between the first common connection and the other separate connections respectively a semiconductor diode or a Zener diode connected in parallel is that its anode on the first terminal and its cathode on the further connection is, with the capacitors and the parallel-connected semiconductor or zener diodes in a common Combination element for connection to the electric motor are integrated. This ensures that that with the electric motor in electrical connection components in front of a caused by the switching off or switching of the electric motor overvoltage protected are. Continue leads the integration of the capacitors and the semiconductor or zener diodes in a combination element to a significant cost savings compared to proprietary devices.
Um eine einfache und schnelle Kontaktierung des Kombielements mit dem Elektromotor zu gewährleisten, stehen die Anschlüsse des Kombielements in einer vorteilhaften Ausgestaltung unabhängig von der Anzahl der Entstörbauelemente in einem festen räumlichen Verhältnis zueinander.Around a simple and quick contact of the combination element with the To ensure electric motor stand the connections the combination element in an advantageous embodiment regardless of the number of suppression components in a fixed spatial relationship to each other.
Weiterhin ist vorgesehen, dass der erste Anschluss mit einem ersten Kontakt des Elektromotors sowie mit einer elektrischen Masse und die weiteren Anschlüsse mit weiteren Kontakten für die jeweiligen Stufen des Elektromotors sowie mit einem Versorgungspotential verbindbar sind. Eine vorteilhafte Ausgestaltung der Erfindung ergibt sich schließlich durch die Integration einer Verpolschutzdiode in das Kombielement derart, dass ihre Anode mit dem ersten Anschluss des Kombielements bzw. dem ersten Kontakt des Elektromotors verbunden ist und ihre Kathode über einen Masseanschluss mit der elektrischen Masse verbindbar ist.Farther is provided that the first connection with a first contact of the electric motor and with an electrical ground and the other connections with further contacts for the respective stages of the electric motor and with a supply potential are connectable. An advantageous embodiment of the invention results finally through the integration of a polarity reversal protection diode in the combination element such, that their anode with the first terminal of the combination element or the first contact of the electric motor is connected and its cathode via a Ground terminal is connectable to the electrical ground.
Weitere Vorteile der Erfindung ergeben sich durch die in den abhängigen Ansprüchen angegebenen Merkmale sowie aus der Zeichnung und der nachfolgenden Beschreibung.Further Advantages of the invention will become apparent from those specified in the dependent claims Features as well as from the drawing and the description below.
