For those who missed the original post....



Hello fellow netters! I was at a local surplus store and found a box full of
drive assemblies for micro recorders.

These assemblies contain two interesting motors:

One is the main drive it is 8mm thick 3cm in diam and has a shaft that is
7mm long that is connected to a pully and speed sensor. This motor has a small
rubber drive belt that goes around a large (3cm) brass wheel that drives the
capstan.

The other motor is used to load and unload the head. At first I thought this
was a small solinoid but then I noticed it had a small worm drive on the end.
It is about 1cm in diam and 8mm long it has a shaft of unknown length with a
worm gear on it. There are other misc gears and switches on the thing.
They appear to be brand new.  Each is in a small zip lock bag. I also have 
the complete specs for these things!

Motor specs:
	Capstan drive motor:
		Type:				Flat coreless motor
		Rated voltage:			1.5V
		Rated Load:			2g/cm
		Rated load revs:		2400rpm
		Rated load current:		105ma
		Starting torque:		over 8g/cm
		Starting current:		under 300ma
		FG output current:		600mV P-P 2400rpm
		FG frequency:			400Hz/2400rpm
		Insulating resistance:		over 1M 250V dc

	Mechanism Drive motor
		Type:				Cylindrical cored motor
		Rated voltage:			1.5V
		Rated Load:			1.5g/cm
		Rated load revs:		5000rpm

Here is the deal:
