80 x Nidec disc drive spindle motor 2021-46FY-10 / MOT00269

box of 80  x Nidec spindle motor 2021-46FY-10 /  MOT00269

this motor has a M6 thread on the stationary center part with the wires and an M3 hole on the other side. The outside turning part has 3 M2.5 holes. It has 4 wires black is common and each of the other wires measures about 2 ohms to the black.

To make them turn you need to switch power from coil to coil.  I could not find any data but would guess the coils are rated at 5 volts when pulsed.

the widest part of the motor is about 31mm diameter the rest is 25mm diameter it is about 26mm tall excluding the M6 threaded part
