Abstract (en)
1. A drum-type counter mechanism, consisting of number drums (23, 24) which are supported to rotate an an axis (22) in a counterframe and having switching pinions (26, 27), which are associated with these number drums and which are supported to rotate on another axis (25), for indexing adjacent number drums (23, 24) to the next position, and having an electric stepping motor which drives the first one (23) of the number drums and which is provided with a stator (11-15), a stator coil (16, 17) and a rotor (20) which is supported to rotate between the poleshoes (11a, 14a) of the stator (11-15) and is arranged coaxially with or parallel to the number drum axis (22) and axially offset with respect to the number drums (23, 24), characterized in that the stator has two shanks (12, 15) which are arranged in parallel with the number drum axis (22) and essentially extend over the whole length of the number drum axis and which, at one end, are joined to each other via a yoke plate (13) and which, on the other end, have pole plates (11, 14) which are in each case arranged at right angles to the shanks and which are provided with the pole shoes (11a, 14a), and that the stator coil (16) is wound onto one or both shanks (12, 15) to be distributed over the whole shank length.
Abstract (de)
Rollenzählwerk, dessen Zahlenrollen (23, 24) über Schalttriebe (26, 27) von einem impulsgespeisten Schrittschaltmotor angetrieben werden. Zur Erzielung eines geringen Platzbedarfes und Herabsetzung des Leistungsbedarfs ist der Schrittschaltmutor in das Rollenzählwerk integriert. Der Stator weist zwei parallel zur Zahlenrollenachse (22) angeordnete Schenke (15) auf, welche an einem Ende über ein Jochblech (13) miteinander verbunden sind. Am anderen Ende weisen diese Schenkel (15) jeweils Polbleche mrt Polschuhen auf, zwischen welchen der Rotor drehbar gelagert ist. Die Statorspule (16) ist wenigstens auf einem der beiden Schenkel (15) über die gesamte Schenkellänge verteilt gewickelt.
