Step-by-step instructions for assembling the ring stator.

Basic overall structure of the telemetry system with ring stator
The picture shows the basic overall structure of the telemetry system with ring stator and the individual layers of the secondary winding.
Attach an overlapping black insulating tape to one end of the mu-metal. Pull off the protective foil.
Now apply the second mu-metal layer. The overlap of this mu-metal layer must be offset by at least 90 ° to the overlap of the first mu-metal layer. So, for example, rotate the shaft by at least 90 ° before applying the second mu-metal layer.

Measure and cut the stranded wire (at least AWG 20 or 0.62 mm2) for the inductive power supply, strip the ends and tin them. Solder one stranded wire each with a maximum length of 100 mm onto the copper strip ends. The connecting leads should be soldered as flat as possible to the copper strip. As drawn in Figure 36, the leads must be aligned at right angles to the copper strip.
Now place the copper strip as secondary winding centrally on the polyimide layer. The distance between the copper ends must be approx. 5 mm.
The soldering points with the stranded wire must not touch each other. The strands must be flat and close together. They must not touch the stator when the shaft is rotated.
The sensor leads should not cross with the connecting leads.
For measurements on shafts with high speed or high temperature, imc offers special solutions (half shells, special housings, etc.)
