5. Insulate the second mu-metal layer completely (see step 1).
6. Apply a first layer of heat resistant tape.
7. Apply the secondary copper winding centrally to the insulated mu-metal (see figure 40).
Please note:
Leave a gap of approx. 1mm between both ends of the copper band. If the
ends of the secondary coil (copper band) contact, the device will not be supplied with
energy.

8. Solder one strand to each of the copper band extremities (the strand
s’ surface should be
as large as possible: 0.62 mm
2
or AWG 20) and a maximum length of 100 mm. These
solder joints must not contact other as well. Make sure the strands lie flat and close to
each other to avoid collision with the stator when rotating. Soldering is easier when the
insulating coat on top of the copper bands is carefully removed and then covered with
soldering tin (see figure 41).

Strands must not contact (min.
distance 2mm).
The ends of the copper strip
must not touch.
The distance should be at least
1 mm.
