INTRODUCTION
To most, the European specialised industrial control equipment this motor was extracted from is just junk - but look beyond the carcass of whatever you may be about to throw away and it is often possible to find a little gem inside, this is one of those "gems"
Sustainability is the name of the game! Anything (that has been tested and still functioning properly) should be repurposed creating saving in wasted Ee and reducing the poisoning our environment when items are buried in the earth at the local tip needlessly.
Never heard of Ee? It is a concept that creates a measurement of ALL things (not just electronics) that humans have made and the energy used in obtaining the raw material, processing the materials right through to a finished product and even should include the shipping of the item to the distributors/retailers.

HISTORY OF THIS ITEM:
Another salvaged part from some obsoleted European special purpose industrial equipment. No one is likely to be servicing the original equipment (EPROM failure) but the four factors which took my interest with this motor are: a) low voltage running 12V b) gearhead c) high torque and last but not least, it is from Philips (Belgium made) - I like Philips components.
This motor could well be an ideal candidate for the "experimenter" who can make use of such a motor in their own custom project.
PHILIPS COMPONENTS - DC Motor With Integral Gearhead
Made In Belgium
Part # 9904 120 52605
Completely thermo plastic encased and there appears to be no way of getting inside. The nylon tie is only to hold the flying leads in place and has nothing to do with supporting the body.
Analog motion control i.e this is not a stepper motor - I used similar motors to these way back in the early days of designing some robotic systems, where the precision of using stepper motors was not required. I seem to recall at the time this type of motor (from a quality manufacturer) cost an absolute arm & a leg!
Running voltage 12V DC
37mA running current (measured when powered in either direction)
Slow rotation of the 4mm OD steel shaft, measured at 72rpm
Gearhead is a spur type
Low operational noise, when running it sounds like a cat purring! (even when stressed i.e I try and stop the rotation manually)
Solder terminals with short leads attached
Bi-directional movement i.e reverse the supply polarity and the motor doesn't object at all, White to positive supply and rotation is clockwise, reverse this and of course rotation is counter-clockwise.
High torque - see below in my test section for my comments about this. Philips made a series of these motors (no longer though) and a common characteristic was a torque of 30N/cm
DIMENSIONS:
BODY: 65mm length
GEARHEAD: 24mm length x 37.85mm OD
MOTOR: 35mm length x 33.1mm OD
4x 2.8mm ID flange mounted holes at the front of the motor
Steel shaft is round (no flat spot) 4mm OD x 10mm length
COMPLETE ASSEMBLY WEIGHT: 124g
TESTING:
Test supply was 12.1V DC
Rotational speed was measured at 72rpm
Current drawn under normal operating condition was 37mA
I do not have a torque meter so I just tried to stop the shaft rotation with my fingers - impossible! This little beastie just keeps on rotating no matter what, my fingers couldn't slow it down at all.
This basic information is intended to give an idea of the motor's suitability for your "project"
