INSTRUCTIONS
General:
This craft pack contains a range of dierent materials to make the rotor holder. This will ensure various degrees of diculty
during the construction proccess.
1. Making the base and end
1.1 Mark out the plan (diagram 1.1) on the acrylic sheet (1).Use a fretsaw and then le and smooth ( Wet & Dry paper) the
sawn edges.
Diagram 1.1
1.2 Mark out the plan (see page 7) on the base and
end. You can cut outthe plan and selloptape it t
the acrylic. Mark the centre of the holes before
drilling (see diagram 1.2)
Note:
Keep the protection foil in place- do not remove !

1.4 For M3 thread use a 2.5mm dia hole,and a 3.3 mm dia hole for M4
thread. ( Use 3 part tap sytem or special one cut tap ) see photo 1.4
Note:
Hold the tap in a vertical position. Check with a try square or similar tool

Important notes for sawing acrylic sheet with a fretsaw
The saw blade will warm the acrylic as it is sawing and cause the
fretsaw blade to stick.Use a few drops of water on the blade as
you are working in order to keep it cool and running free. Ensure
that you use a medium saw blade( not too ne or coarse )

1.3. Drill the holes ø 2,5, ø3,3 and 4mm dia.
(see pattern and photo 1.3)
Please Note:
Use a drill for plastic or a metalworking
drill!

1.5. Drill the two ø5 mm holes into the rear of the base at laest 4mm deep. (see
photo 1.5)
Please note:
Use a depth gauage!
Alternatively instead of countersinking you can drill a blind hole 10mm dia.
6-8mm deep This has the advantage, that for xing the side part more of the
screw thread can be used.

2. Making the bearing (2 designs)
Variation 1:
2.1 Work the at strip (4) as shown in 2.1
Note:
Use a Fretsaw with a metalworking blade! drill out to 6mm
dia
Enlarge hole with
a saw
Dia. 2.1
Variation 2:
2.2 Meaure 50mm on the aluminium strip (3) .Round the end of the strip with a
le. Use the pattern ( see page 7) to mark out the holes on the aluminium
strip. Drill the holes and bend the metal strip at 90 degrees as shown ( see
photo2.2)
Dia. 2.2
3. Making the drive (Magnet holder)
3.1 Mark out the holes using the pattern (see page 7) on the acrylic sheet (2) Drill
the 4 marked holes with a 15mm dia Forstner drill , 3.5mm deep. (see photo
3.1) Use a depth guage!
Please Note:
Drill carefully so that the acylic sheet is not drilled through. Make sure all the
holes are drilled at the same depth so that it will rotate smoothly!
Photo 3.1
3.2. Drill the central ø 4mm hole all the way through (see photo 3.2)
Photo 3.2
3.3. Glue the 4 magnets in the bilind holes as shown using an all purpose glue (see
photo 3.3)
Note:
use the glue sparingly!

4. Winding the coil
INSTRUCTIONS
4.1.Wrap the machine screw(8) with a layer of sellotape. Starting at the hexangonal
head wrap the sellotape around for a length of 18mm Then add a nut (9) screw-
ing it up to the edge of the sellotage.
Cut a ca.200mm length of copper wire (5) This will be needed at a later stage!
From the rest of the wire remove a length of the insulation (100mm ) from both
ends of the copper wire. Stating at the nut end wind the wire evenly and neatly
around the insulated part of the machine screw .About 5 layers in all ) (see
photo 4.1)
Start point for
winding
4.2. Once all the wire has been wound on the coil twist the ends together to stop it
from undoing Photo 4.2

5. Final assembly
5.1. Screw the end part Photo 5.1 using the contersunk head screws (12) on to the
base from underneath, tighten. Photo 5.1
5.2. Insert the brass tube (15) in the hole in the end (see Photo 5.2)
Photo 5.2
5.3. Insert the cheesehead screw (13) from the front (Magnet side) through the rotor
(see step 4) and x it with a nut (10). (see Photo 5.3) Photo 5.3
4.3. Mount the at strip, aluminium on to the machine screw and tighten wth nut
(9). (Photo 4.3)

5.4. Insert the magnet holder and machine screw through the brass bearing (15) (see
Photo 5.4)
Note:
Add a drop of oil to the bearing!
5.5. Fix the machine screw with 2 nuts (10) contra tighten the nuts so that the rotor
can spin.
Note: Check that the rotor turns easiy
Hinweis:
Muttern so kontern, dass der Magnethalter leicht und spielfrei drehen kann.
INSTRUCTIONS
5.6. Fix the coil holder Photo 5.6 with a machine screw (14) and washer (16) on the
base( see Photo 5.6)
Distance ca. 2-3mm from the magnets
Note:
The slot in the stand allows the coil to be adjusted to the magnet rotor

5.7. Take one end of the wire from the coil to a connector block (11) at tighten in
place. (see Photo5.7)
5.8. Carefully bend the ends of the reed contact with a
pair of pliers. Note the position of the contacts.
Insert one end of the reed contact (6) in the other
end of the connector block (11) and tighten. (see
Photo 5.8)

5.10. Cut a ca. 20-30 mm long piece from the remainder of the copper wire, remove the insu-
lation from the ends and bend it at 90 degrees in the middle. Fix it in the connector block
(s.step 5.9) Photo 5.10
5.11. Take a ca. 60mm long length and remove the insulation
from both ends and x it to the connector block (11) Arrange
the reed contact (6) so that it exactly alongside the middle
of the coil and exactly in the middle of a magnet (7) te exact
positon can be adjusted with the connector block
( see Page 5.12)
5.11. Fix the last connector block on the base with a mchine
screw ( 14). (see Photo 5.11)
Finally connect the two connector blocks with the wire . (see
Photo 5.11 right)
Bild 5.12
6. Testing the function
6.1 Connect a 4,5 V Flat shaped battery to the wire ends ( Insulation remo-
ved ) and then spin the rotor
Should the motor not start up,adjust the position of the reed contact
and check all the connections
