I cannot remember and unfortunately did not record the equipment this motor was removed from!
I 'suspect' it may have been PIONEER equipment as the PXM numbering system was used by them extensively for their various motors but the original manufacturer was HOSIDEN - a general electronic component supply company based in Japan, formed in 1950.
Great little motor (or generator) for low voltage use
HOSIDEN - DC Motor
Model: HMR-32 (PXM-148 A 5120T)
DC direct shaft rotation, NO gearhead
DIMENSIONS:
Body - 32mm diameter x 20.5mm height
Central shaft - 2mm diameter shaft, length 12.5mm
Top of the shaft has a brass pulley fitted
Brass Pulley - 5mm height x 7mm diameter (appears to be press fit as I can see no screws or other means of securing the pulley to the shaft)
Motor top body has 2x top mounting threaded bolts (supplied) with the holes spaced 21mm apart
403mm flying power lead (2 wire) terminated with a sub-miniature molex style female plug
Bi-directional rotation.
COSMETIC CONDITION:
Clean and undamaged in any way
TESTING:
Cold DC windings resistance: 33 Ohm
Powered up with a 12V DC power source (guess-timated voltage), rapidly spins up and runs quietly, in either rotational direction
I cannot measure the rpm but it spins fine and quite fast, something like you would expect from a cassette deck main drive motor.
Torque has not been measured but there is plenty of it!
But what there's more!
Like most DC motors, you can use this in reverse so that it acts as a small generator. Link to the shaft some rotational motion and the motor becomes a generator, with the output voltage at the connection pins. Simple rapid spinning of the shaft and I was easily able to achieve more than 3V output at the output.
Stored and supplied in sealed plastic
