KLASSE 21: Elektrische Apparate,CLASS 21: Electrical apparatus,
Der neue Commutator besteht aus einer flachen Scheibe aus nichtleitendem Material, die auf ihrer Vorderfläche mit Kupferstreifen versehen ist. Diese sind so angeordnet, dafs der Durchmesser, auf welchem die Bürsten sich reiben, η. α Streifen schneidet, wenn η die volle Zahl der Streifen ist und α die Zahl derjenigen Streifen, welche aus dem Stromkreis ausgeschlossen sind und mit den Rollen correspondiren, welche durch die neutrale Region des magnetischen Feldes gehen.The new commutator consists of a flat disk made of non-conductive material, which is provided with copper strips on its front surface. These are arranged so that the diameter on which the brushes rub is η. α stripes intersect if η is the full number of stripes and α is the number of those stripes which are excluded from the circuit and correspond to the rollers which go through the neutral region of the magnetic field.
Die Streifen sind von epicycloidaler Gestalt. Fig. ι und 2 zeigen die Details eines solchen Commutators, der hier doppelte Flächen hat. α sind die epicycloidalen Kupferstreifen, welche durch ein Isolirmaterial oder durch eine Luftschicht von einander getrennt sind und von welchen jeder Streifen mit einer oder mehreren Rollen des Armaturringes verbunden ist. Diese Streifen sitzen auf der Isolirscheibe b. Die Metallbürsten c (in Fig. 1 durch punktirte Linien dargestellt) streifen mit ihren Enden auf demselben Durchmesser der so construirten Scheiben auf entgegengesetzten Seiten der Achse, eine oben und eine unten, und sind durch elastische Leitungen/ mit Klemmschrauben verbunden.The stripes are epicycloidal in shape. Fig. Ι and 2 show the details of such a commutator, which here has double surfaces. α are the epicycloidal copper strips which are separated from one another by an insulating material or by a layer of air and of which each strip is connected to one or more rollers of the fitting ring. These strips sit on the insulating disk b. The metal brushes c (shown in Fig. 1 by dotted lines) brush with their ends on the same diameter of the discs thus constructed on opposite sides of the axis, one above and one below, and are connected by elastic lines / with clamping screws.
Die Bürsten c sind durch Schrauben d in Halter eingeklemmt, welche zusammengekuppelt sind und sich längs einer ringförmigen, concentrischen Führung e bewegen lassen. Die Schrauben d sind durch die biegsamen Bänder f mit den Klemmschrauben der Maschine verbunden und von der Führung e isolirt.The brushes c are clamped by screws d in holders which are coupled together and can be moved along an annular, concentric guide e . The screws d are connected to the clamping screws of the machine by the flexible straps f and isolated from the guide e.
