I hypothesize that by detaching the field coil and using the signal to trigger a transistor, it should be possible to trip a larger motor over one pol...
having come across instructables on equatorial mounts I wondered why no one used a quartz movement as the power source I quickly realised it is because they produce very low torque. I wondered if there was anything thing that you could do to improve it so as a starting point I took one apart to see.
thankfully the designer decided a couple of moulded in clips would save messing around with glue, so it's a simple case of popping them undone and gently easing the case appart. I used a small screwdriver but I could probably of managed just with finger nails.
Step 2: I didn't want to do that
I missed a clip in the battery compartment and used a little too much force. Not to worry I've repaired mechanical alarm clocks before this shouldn't be a problem to resemble.
Step 3: The power source
the reason a quartz movement doesn't produce much torque is that basically what you have is a small 2 pole brushless motor kicked around one pole at a time by a pulse to the windings from an encapsulated chip and a quartz crystal.
Step 4: Lets put it back together
unlike a traditional mechanical clock where the gear train is mounted between 2 plates. The gear train for this quartz clock are mounted either side of a central plate sandwiched between the two halves of the case. The first thing to reinstall is the minute hand drive. This is driven by a small gear that passes through the mounting plate.
Step 5: The hour hand drive
the hour hand is driven by an intermediate reduction gear and has a hollow shaft that runs on the outside of the minute hand shaft.
Step 6: Refitting the Central plate
first the electronics need to be reinstalled in the case. The board and field coil locate on 4 pins 2 of the pins also help locate the central plate. Once the central plate is in place the front section of the case has to be supported on a hollow support.
Step 7: Refit the armature
the armature mounts on a shaft between the two poles of the field coil.
