- FIG shown Another embodiment of a twisting spindle is shown in FIG shown, which is different from the embodiment only differs according to Figure 1 in that here is working with a free thread balloon and thus the balloon limiter connected to the spindle rotor disc eliminated.
- Figure 2 are those of the embodiment Figure 1 corresponding components with the same reference numerals referred to, each with an apostrophe are provided.
- Regarding the construction of the spindle refer to the description of Figure 1.
- FIG 3 is easy compared to Figures 1 and 2 enlarged the arrangement of the transformer 6 the twisting spindle, which is only indicated by dashed lines here, shown.
- the primary part of the transformer 6 is in the wall 3.2 of the stationary outer housing, while the secondary part 6.2 in the also stationary Wall 8.3 of the chamber 8 is arranged. Between these an air gap 9, whose Width is such that the thread balloon and the Embodiment according to Figure 1, the balloon limiter through can be moved through it.

- this control unit 10 here generated carrier signal that has a frequency between Can have 10 and 30 kHz and that for energy transmission serves, assigned to the control signals a control signal specific Frequency modulation imprinted.
- the resulting frequency-modulated signal is from the primary part 6.1 of the transformer 6 transferred to the secondary part 6.2. So there is both energy transfer, as well as data transmission over the same winding of the primary part and the secondary part.
- the secondary part 6.2 is via a rectifier bridge 11 and optionally a voltage stabilization 12 to the Energy inputs of components connected in figure 4 referred to as "functional element 1" and “functional element N" are, and in the present example by the two Electric motors 4 and 5 are represented.

- FIG. 5A shows a possible voltage curve over time of the frequency-modulated primary voltage / secondary voltage generated by the control unit 10.
- these signals are designed as square-wave signals. However, it can be both sinusoidal and rectangular.
- the amplifier 13 which is connected as a voltage comparator, a square-wave voltage is present at the input of the evaluation electronics 7, regardless of the rectangular or sine shape of the voltage fed in.
- the supply voltage of frequency f B base frequency
- the frequency of the supply voltage changes according to the bit pattern to be transmitted between the base frequency f B and a second frequency f O (offset frequency).
- the frequency changes such as level changes in asynchronous transmission methods are evaluated in the electronic unit 7.
- the interpretation of the signals in the evaluation electronics is shown in FIG. 5C.
- the frequency f O can optionally be greater or smaller than the base frequency f B , the frequency / level assignment of course having to be interpreted or evaluated in the same way in the control unit 10 and evaluation unit 7.
- a high-low edge change is interpreted as a start bit.
- FIGS. 5A to 5C A method is illustrated in FIGS. 5A to 5C, in which the frequency change within a period the supplied AC voltage is evaluated.
- N integer period numbers
- the interference immunity of the process e.g. by averaging to increase.
- too a different integer number of consecutive Pulses of the same frequency agreed or defined be the number N and M for the two frequencies can be chosen so differently that approximately same times for the transmission of low and high levels result (this is the usual asynchronous transmission method the next). Because of the inevitable interference signals such a transmission path is sensible in all of the aforementioned variants, thanks to the evaluation electronics Edge changes only in such Evaluate time windows that correspond to the agreed period of base and offset frequencies.
- a 10-bit frame (a start bit, 8 data bits and a Stop bit) is used.
- the bits transmitted are through the evaluation electronics combined into a data word (byte).
- the bits can also be used for data structures consisting of any number of data bytes combined become.
- a transferred Data block can be created in a known manner by checksuming (e.g. CRC check) are saved so that transmission errors recognized and taken into account by the evaluation electronics can. Transmission errors lead to a standstill of the controlled motors. This can be done by simple sensors outside the rotating device unit can be detected.
- the evaluation electronics can modulate the Cause current consumption caused by current sensors in the converter of the primary energy supply evaluated becomes.
- the error-free data transmission can thus be acknowledged become.
