Description
<Desc/Clms Page number 1>
Elektrische Handwerkzeugmaschine mit einem Einphasen-Motor mit Kondensator
EMI1.1
<Desc/Clms Page number 2>
parallel zur. Motorachse bewegt. Die Flachstange 15 ist bei 17 parallel zur Stirnfläche 18 des Lüfters 19 gebogen und mit dem Bremsbelag 20 versehen. Die Zugfeder 21 ist bei 22 und 23 eingehängt und zieht die Flachstange 15 immer in die Bremsstellung. Die Bremslüftung erfolgt durch den Lauf der Leitrolle
13 auf dem Umfang der Hülse 11 bei Betätigung des Drehgriffes 3.
Wie ersichtlich, ist für die Erfindung wesentlich, dass der Drehgriff 3 aine dreifache Funktion besitzt : Er dient zunächst zum Festhalten der Maschine ; ausserdem wird durch seine Betätigung die Ein- und Ausschaltung des Motors bewirkt. Von besonderer Bedeutung ist nun, dass in den Hohlraum des Drehgriffes 3 der zylindrische Kondensator 4 eingebaut ist.
PATENTANSPRÜCHE :
1. Elektrische Handwerkzeugmaschine mit einem Einphasen-Motor mit Kondensator zum Anlauf in beiden Richtungen, dadurch gekennzeichnet, dass der Kondensator, mit dem eigentlichen Maschinengehäuse fest verbunden, in dem hohlen Drehgriff, der gleichzeitig zur Betätigung des Ein-, Aus- und Umschalters dient, so eingebaut ist, dass der Handgriff (Drehgriff) frei drehbar ist und eine auf ihm sitzende Kurvenscheibe (11) vorgesehen ist, die eine Bremsvorrichtung zur sofortigen Stillsetzung des Läufers betätigt, sobald in die andere Bewegungsrichtung umgeschaltet werden soll.

parallel to. Motor axis moves. The flat rod 15 is bent at 17 parallel to the end face 18 of the fan 19 and provided with the brake lining 20. The tension spring 21 is suspended at 22 and 23 and always pulls the flat rod 15 into the braking position. The brake is released by running the guide pulley
13 on the circumference of the sleeve 11 when the rotary handle 3 is actuated.
As can be seen, it is essential for the invention that the rotary handle 3 has a threefold function: it is used first of all to hold the machine in place; in addition, its actuation causes the motor to be switched on and off. It is of particular importance that the cylindrical capacitor 4 is built into the cavity of the rotary handle 3.
PATENT CLAIMS:
1. Electric hand tool with a single-phase motor with capacitor for starting in both directions, characterized in that the capacitor, firmly connected to the actual machine housing, in the hollow rotary handle, which is used at the same time to operate the on, off and changeover switch, is installed in such a way that the handle (twist grip) can be rotated freely and a cam disc (11) is provided on it, which actuates a braking device to stop the rotor immediately as soon as the other direction of movement is to be switched.
