Description

1. Allgemeines1. General

Elektrofahrzeuge aller Art werden mit einem Gleichstrommotor betrieben. Dies ist verständlich und naheliegend, weil aus den Batterien nur Gleichstrom zu entnehmen ist.Electric vehicles of all types are powered by a DC motor operated. This is understandable and obvious, because from the Batteries can only be taken from direct current.

2. Stand der Technik2. State of the art

Früher wurde die Drehzahl des Motors und somit die Geschwindigkeit der Fahrzeuge über Widerstände geregelt. Bei Höchstdrehzahl des Motors floß der Strom direkt in den Motor. Beim Anfahren wurde der Strom über Widerstände geleitet, wodurch dieser teilweise vernichtet wurde. Der Reststrom trieb den Motor an.In the past, the engine speed and thus the speed of the vehicles regulated via resistors. At maximum speed the current of the motor flowed directly into the motor. When starting the current was passed through resistors, which partially was destroyed. The residual current drove the motor.

Heutzutage wird der Strom über Transistoren und Thyristoren geleitet und in Stromimpulse zerlegt. Dabei wird dem Motor entsprechend der gewünschten Fahrgeschwindigkeit mehr oder weniger lange Impulsströme zugeleitet. Auf diese Weise wird kein Strom mehr vernichtet.Nowadays the current is through transistors and thyristors conducted and broken down into current pulses. This will match the engine the desired driving speed more or less long pulse currents supplied. This way there is no electricity destroyed more.

3. Aufgabe und Zielsetzung3. Task and objective

Der allgemein verwendete Gleichstrommotor bringt große Nachteile in bezug auf Wartung und Lebensdauer mit sich. Dem stromführenden Anker muß über sogenannte Kohlebürsten Strom zugeführt werden. Wenn diese verschleißen, liegen die Kohlebürsten nicht mehr gut an und es besteht dann die Gefahr, daß der Kollektor verschmort und der Elektromotor unbrauchbar wird.The common DC motor has major disadvantages in terms of maintenance and durability. The live one Anchor must be supplied with electricity via so-called carbon brushes will. If these wear out, the carbon brushes do not lie more well and there is then a risk that the collector scorched and the electric motor becomes unusable.

Beim Elektrofahrzeug wird heutzutage die sogenannte Nutzbremsung angewandt, d. h., daß beim Schiebebetrieb des Fahrzeuges der Motor als Generator umgepolt wird und somit die Batterien auflädt. Bei dieser Umpolung "feuern" die Kohlebürsten sehr stark, wodurch der Kollektor und die Kohlebürsten noch mehr beansprucht werden und somit die Wartung dieses Elektromotors öfter durchgeführt werden muß.Nowadays, so-called regenerative braking is used in electric vehicles applied, d. that is, when the vehicle is in overrun the motor is reversed as a generator and thus the batteries charges. With this polarity reversal, the carbon brushes "fire" very much strong, which makes the collector and carbon brushes even more are claimed and thus the maintenance of this electric motor must be carried out more often.

Deshalb bin ich auf den Gedanken gekommen, einen Motor ohne Kohlebürsten zu verwenden. Dafür kam nur ein Motor infrage, der keinen stromführenden Anker aufweist. Zunächst sollte ein Gleichstrommotor mit Permanentmagnetanker im Elektrofahrzeug eingesetzt werden; dieser Motor ist aber noch nicht serienreif. Deshalb mußte auf einen Drehstrommotor zurückgegriffen werden, wobei aber der Gleichstrom, welcher aus den Batterien gezapft wird, in Drehstrom umgeformt werden muß.That's why I came up with the idea of an engine without To use carbon brushes. Only one engine came into consideration that has no live armature. First of all, one should DC motor with permanent magnet armature in the electric vehicle be used; this engine is not yet ready for series production. Therefore, a three-phase motor had to be used but with the direct current drawn from the batteries is converted into three-phase current.

Mit dieser Anordnung soll das Elektrofahrzeug wartungsfrei gemacht werden und eine lange Lebensdauer haben.With this arrangement, the electric vehicle is to be maintenance-free made and have a long lifespan.

4. Aufbau meiner Drehstromanlage für Elektrofahrzeuge4. Setup of my three-phase system for electric vehicles

Von dem Batteriepaket (1) - siehe Zeichnung - wird der Strom in den Umrichter (2) geleitet. Dieser formt auf elektronischem Wege den Gleichstrom der Batterien in Drehstrom um. Mit dem Fahrregler (3), den der Fahrer über das sogenannte Gaspedal betätigt, wird die Änderung der Frequenz gesteuert, welche die Drehzahl des Drehstrom-Motors (4) regelt.
Das Ladegerät (5) dient zum Wiederaufladen der leergefahrenen Batterien im Batteriepaket (1).The current is conducted from the battery pack ( 1 ) - see drawing - into the converter ( 2 ). This electronically converts the direct current of the batteries into three-phase current. The change in frequency, which regulates the speed of the three-phase motor ( 4 ), is controlled with the drive controller ( 3 ), which the driver actuates via the so-called accelerator pedal.
The charger ( 5 ) is used to recharge the empty batteries in the battery pack ( 1 ).
