The part number on that one appears to be D-001-484A, which is slightly different to D-001-688 (683?)V on the photo above. It is not clear if that is a 4-wire.
Other US eBay listings have 3 wire and 5 wire DCM motors, so the number might be important.
It could be useful to find DCM's website/catalogue and see how the part number correlates to the motor characteristics.
