Abstract
Außenläufermotor (
Description
Außenläufermotor mit einem 2- oder mehrfach geteiltem Stator aus unterschiedlichem Material und einer integrierten Elektromagnet-Bremse ohne mechanische Handlüftung.External rotor motor with a 2 or more divided stator of different Material and an integrated solenoid brake without mechanical Manual release.
Außenläufermotoren
sind schon seit Jahrzehnten bekannt und werden häufig als
Fahrantrieb in Rollstühlen und Scootern im REHA-Bereich
und in Batterie betriebenen Fahrzeugen wie Bodenreinigungsmaschinen,
Fahrrädern, Golf-Caddies, Kleintransportern usw. eingesetzt.
Zum Überwinden von Hindernissen wie z. B. einen Bordstein,
fehlt oft die notwendige Spitzenleistung, die nur durch eine größere
Bauweise des Antriebs möglich ist. Dies wiederum führt
zu einem größeren Gewicht, das bei solchen Einsätzen
gering sein sollte und höheren Herstellungskosten. Elektromotoren
mit geteilten Statoren sind aus der
Speziell bei Rollstühlen und Scootern im REHA-Bereich ist die in der Radnabe sitzende Elektromagnet-Bremse oft nur unhandlich und mit Kraftaufwand zu bedienen und ist in der Herstellung durch die spezielle Bedienung sehr aufwendig. Da kein Getriebe zwischen Motor und Rad existiert, benötigt die Bremse ein hohes Bremsmoment und braucht somit einen hohen Haltestrom während der Fahrt um sie offen zu halten. Dies reduziert die Reichweite des Fahrzeugs wesentlich, da der Versorgungsstrom aus der Motorbatterie kommt.specially for wheelchairs and scooters in the REHA area, the in The wheel-mounted solenoid brake often just unwieldy and to use with effort and is in the making by the special operation very expensive. Because no gearbox between engine and Rad exists, the brake needs a high braking torque and thus needs a high holding current while driving to keep her open. This reduces the range of the vehicle essential, because the supply current comes from the engine battery.
Der erfindungsgemäße Außenläufermotor mit den Merkmalen des Anspruchs 1 hat den Vorteil eines 2- oder mehrfach geteilten Stators, wobei dieser aus einem Rückschlussring aus nichtkornorientiertem Elektroblech mit Aussparungen am Außendurchmesser zur Aufnahme der Stege und den einzelnen Stegen aus kornorientiertem Elektroblech besteht. Der Rückschlussring kann auch in mehrere Segmente mit den gleichen Merkmalen aufgeteilt sein. Sternförmig kornorientiertes Elektroblech ist nicht herstellbar, wogegen die Stege zur Leistungssteigerung aus kornorientiertem Elektroblech hergestellt werden können. Die Stege müssen so gestanzt oder gelasert werden, dass die Kornorietierung in Längsrichtung der Stege verläuft. Der Ummagnetisierungsverlust von kornorientiertem Elektroblech beträgt 0,73 W/kg und ist somit deutlich besser als bei nichtkornorientiertem Standart-Elektroblech mit 4,1 W/kg. Dadurch kann der Stegquerschnitt bei gleichem Magnetfluss verringert werden, wodurch mehr Volumen zwischen den Stegen entsteht. Mit einer zu berechnenden Kombination von Stegquerschnittreduzierung und größerem Volumen kann durch Verwendung eines dickeren Wickeldrahtes eine bis zu 54% höhere Antriebsleistung erreicht werden. Die Stege selbst können alternativ nochmals in Steg und Stegkopf geteilt sein, wobei der Stegkopf zur besseren magnetischen Leitung aus Magnetpulver oder einer Magnetpulvermischung bestehen sollte, in der Mitte eine Aussparung zur Aufnahme mit dem Stegpaket hat und für die benötigte Statorlänge hergestellt sein muss. Der Stegkopf wird nach dem Wickeln der Stegpakete mit diesen verklebt.Of the External rotor motor according to the invention The features of claim 1 has the advantage of a 2 or more times divided stator, this one from a return ring made of non-grain-oriented electrical steel with cutouts on the outside diameter for receiving the webs and the individual webs of grain-oriented Electrical sheet exists. The return ring can also be in several segments with the same characteristics be divided. star shape grain-oriented electrical sheet is not produced, whereas the Webs to increase performance from grain-oriented electrical steel can be produced. The bridges must be like that be punched or lasered, that Kornorietierung in the longitudinal direction the walkways runs. The re-magnetization loss of grain-oriented Electrical sheet is 0.73 W / kg and is thus much better as with non-grain oriented standard electric sheet with 4.1 W / kg. As a result, the web cross-section can be reduced with the same magnetic flux which creates more volume between the webs. With a to calculate combination of web cross section reduction and larger Volume can be increased by using a thicker winding wire Up to 54% higher drive power can be achieved. The bridges You can alternatively use the bridge and bridge head again be shared, with the bridge head for better magnetic conduction should consist of magnetic powder or a magnetic powder mixture, in the middle has a recess for receiving the web package and manufactured for the required stator length have to be. The web head is after winding the web packages with glued to this.
Der erfindungsgemäße Außenläufermotor nach Anspruch 1 mit einer Elektromagnet-Bremse und ohne mechanische Handlüftung hat den Vorteil, dass die Bedienung der Bremse vom Bedienpult aus einfach und leicht zugänglich erfolgen kann. Die Stromversorgung findet durch einen von der Motorbatterie getrennten Stromkreis mit eigener Batterie statt, wobei die Elektronik die Ansteuerung der Stromabsenkung ausführt. Hierdurch entfällt der aufwendige mechanische Aufbau der Handlüftung und es ergibt sich eine zusätzliche Gewichtsersparnis sowie eine wesentlich größere Reichweite des Fahrzeugs. Durch die elektronisch gesteuerte Stromabsenkung nach dem hohen Stromstoß zum Lüften der Bremse, lässt sich der Haltestrom während des Fahrbetriebs um ein Vielfaches absenken, z. B. bei einer Bremse mit 5 Nm Bremsmoment von 16 A auf 0,8 A. Mit minimalen Anpassungsänderungen können handelsübliche Elektro-Magnetbremsen eingesetzt werden.Of the External rotor motor according to the invention Claim 1 with an electromagnetic brake and without mechanical manual release has the advantage that the operation of the brake from the control panel easy and easily accessible. The power supply takes place through a circuit separate from the engine battery own battery instead, the electronics controlling the current reduction performs. This eliminates the complex mechanical Construction of the manual release and there is an additional Weight savings and a much larger Range of the vehicle. Due to the electronically controlled current reduction after the high current surge to release the brake, can the holding current while driving lower by a multiple, z. B. in a brake with 5 Nm braking torque from 16 A to 0.8 A. With minimal adjustment changes Commercially available electric magnetic brakes can be used become.
Zu den unter 2. aufgeführten Einsatzbereichen für Niedervolt gibt es im industriellen Bereich mit Netzspannung fast unendlich viele Einsatzmöglichkeiten und zwar als Innenläufer wie auch als Außenläufer: Windgeneratoren, Druckmaschinen, Fördertechnik, Zerspanungsmaschinen, Verpackungsmaschinen, Pumpenantriebe, Rührwerke, Wickelantriebe, Textilmaschinen, pharmazeutische und medizinische elektrisch betriebene Geräte, Torantriebe usw..To the applications listed under 2. for Low voltage is available in the industrial sector with mains voltage almost infinitely many uses as an inner rotor as well as external rotor: wind generators, printing machines, Conveyor technology, cutting machines, packaging machines, Pump drives, agitators, winding drives, textile machines, pharmaceutical and medical electrically powered devices, Door drives etc ..
