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

Umwickeln der Welle mit Gewebeband. Die isolierte Fläche muss auf beiden Seiten breiter als das anschließend aufzubringende Mu-Metall sein, um einen Kurzschluss des Mu-Metalls mit der Welle zu verhindern.

The individual components of the mounting set.

Calculate the length of the mu-metal with the formula π * diameter + 10 mm. For the diameter, include the previously applied insulating layer.

Cut the first layer of mu-metal with protective film to the required length.

Apply an overlapping black insulating tape to one end of the Mu metal.

Pull off the protective foil and stick the mu metal onto the shaft. The ends must not touch, there must be no short-circuit winding with the mu metal.

Now insulate the Mu metal as described under 1.

Now calculate the length of the second mu-metal layer using the formula π * diameter + 10 mm.

Cut the second Mu metal layer to this length.

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.

Apply the first layer of heat-resistant Kapton tape (polyimide tape) in the center.

Calculate the length of the copper tape for the secondary winding using the formula π * diameter - 5 mm.

Cut the copper tape to size.

Tin both ends of the copper strip.

Now attach the Dx-SCT transmitter unit in a suitable manner.

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.)

Solder the wire ends to the IP1 and IP2 terminals of the Dx-SCT transmitter unit.

To secure against centrifugal forces and for protection, the transformer winding must be wrapped with the supplied fabric tape.

Calculate the length of the copper ring: (40 mm + diameter) * π + 2 * L

Shape the copper wire: Bend the ends and form a bow.

Press the copper tube together at both ends.

Drill a 5 mm diameter hole in each end of the copper tube.

Important: Sand the contact surfaces of the copper tube to reduce resistance.

Screw the primary winding to the ring stator.

Important: Set the output power regulator to the minimum position by turning it counterclockwise to avoid overvoltage.  

Connect the supply cable to the ring stator.

Connect the supply cable to the ring stator.
