This is a bearing and magnetic rotor hub for the PMSM (model # DC31-00155B) used in a Samsung washing machine. It is normally attached to the washer drum in the washing machine. This 3D print design allows it to be run independently of the washer drum. This particular motor has 18 stator slots and 70 magnetic poles. It is 3 phase. It is rated for 310 VDC and 2.5 amps rms and works best with a PMSM controller. The motor can be purchased on Ebay or Amazon. An example of a good test controller for this type of motor is the STEVAL-IHM023V3
You can use this motor for many DIY projects. It can also be harnessed as a 3-phase HV HF generator. The shaft size for this print is 3/4" The bolts are 1/4" diameter. The length for the bearing rotor bolts should be 3" in length to provide you with enough to mount on a board or piece of metal. The bolts on the magnetic rotor should be 1-1/4" in length. You should drill and tap the magnetic rotor for the 1/4" diameter bolts. The bearings should be 3/4" x 1 5/8" x 7/16" such as these: https://www.vxb.com/R12ZZ-Shielded-Bearing-3-4-x1-5-8-x7-16-inch-p/kit7529.htm
