Coiling ferrite ring
Ideally, ferrites made of manganese-zinc material are used that are active in the 1…10 MHz
range. Typical diameters are between 25 and 35 mm onto which two to three windings
with all 3 motor phases are wound simultaneously.

1. Fasten motor phase cables, e.g., with cable ties (1), so that the motor side end of the
cable points away from the user and the plug end of the cable points toward the user.
2. Simultaneously guide all three phases through the ferrite ring from below.
3. Guide the wound stranded wires back through the ring clockwise next to the first
stranded wires so that a winding is created.
4. Wrap 2 further windings directly next to the existing windings in the same way.
There are 9 stranded wires in the ferrite ring.
5. Again secure the motor phase cables, e.g., with cable ties (2), on the ferrite ring.
