In FIG. 2, TeQ 1 is the printed circuit board carrying the electrical components. This is above pillar 2 with a first work plate 3 made of plastic connected. This in turn is connected to a pillar 2 second Wejrfcplatte4.

The work plate 3 carries the two stator plates 5 and 6. For this purpose, there are several on the work plate 3 Projections 7 molded into corresponding holes

IO in turn meshes with an intermediate wheel 22. The intermediate wheel 22 meshes with its pinion with the wheel 23, the pinion of which in turn meshes with a further intermediate wheel 24. The pinion of the Zwiscnenrades 24 is in engagement with the wheel 25. The wheels 19, 22 and 24 are arranged coaxially to one another and are supported by a common shaft 26 between the work plates 3 and 4 The wheels 21, 23 and 25 are arranged coaxially and supported between the work plates 3 and 4

The printed circuit board 1 carrying the electronic components is provided with two pins 26 protruding from it provided in the area of the two coil ends

Molded projections 7, the corresponding

engage in 8 of the stator laminations 5,6. As a result, one of the motor coils 9 protrudes. They are used to connect the

exact spatial position of these stator laminations to each other _Is ends of the motor coil 9. Optionally, the two

ihtllt Di both gate plates are flat pins being firmly attached to the bobbin being they

ensured The two stator laminations are flat and lie in the same plane, so that they no turns, as is usual, that too would lead to an unnecessary increase in tolerance.

The legs of the two stator laminations 5, 6 on the coil side abut each other and are held by one inside the coil 9 arranged core 10 overlapped. The arrangement is preferably made so that at least one of the legs of the stator laminations 5, 6 together with the core 10 in the interior of the coil 9 is arranged at the point where the core 10 is the leg of a stator lamination 5 or 6 outside the Fastening means 11, for example in the form of a tubular rivet, are provided which extend over the coil Stator plate 5 or 6 and the core 10 connects to the work plate 3

The work plate 3 also has a cup-shaped recess 12 which is provided with a bearing 13 for the rotor 14. The other rotor bearing 15 is located on a bridge 16 which is connected to the work plate 3 _J5

Inside the cup-shaped depression 12 6 an auxiliary yoke is spaced from the stator laminations 5, located 17 This auxiliary yoke 17 has a slightly different pole position to be given as the stator laminations 5, 6, whereby the ^ ₀ the rotor 14 during operation of a preferential direction of rotation. The motor is designed as a stepping motor

The cup-shaped recess is on the side with a

Pins firmly attached to the bobbin, taking them protrude into holes in the circuit board and are conductively connected to it.

In the embodiment of Figure 3, the quartz-controlled unit is flanged to a time-proportional running recorder shown In this exemplary embodiment, the working plate 3 integrally to it a clamp 27, to which a bearing for the rotor 14, 20 is arranged, as the section AA

■ according to FIG. 4 shows, the other rotor bearing is provided on the other work plate 4.

The permanent magnetic part 14 of the rotor penetrates the plane of the work plate 3. At the Stator laminations 5, 6 opposite side of the

, Work plate 3, the auxiliary yoke 17 is provided. This auxiliary yoke 17 is provided with holes in which

^ / or projections of the work plate 3 engage. By Heating the ends of these projections can be achieved that the auxiliary yoke 17 in a simple manner is being held.

The pinion 20 of the rotor engages in an intermediate gear, which in turn is a further intermediate gear 28 able to drive. This intermediate wheel 28 is in engagement with its pinion with the first wheel 30 of the Registration device 29. To ensure a perfect alignment between the pinion of the wheel 28 and the wheel 30 received, a pin 31 is provided on the outside of the work plate 4 which is coaxial with or at least in the vicinity the axis of the wheel 28 runs This pin 31 engages in

Incision 18 provided through which the wheel 19 with ₄₅ a hole in a work plate of the recording device 29 ld R 14 i Eiriff ht D Rd 19 i Di it i F i 5 it

the pinion 20 of the rotor 14 is in engagement. The wheel 19 meshes with its pinion in the wheel 20, the pinion a. This is in FIG. 5 shown
