3 phase bldc motors as a turbine. i am quite confused on how to determine which leads to us or how to configure them.

ive got some electrical backround but dc seems to be where i get lost.  these motors i have were used in some sort of factory.  the motor has three leads and a ground. any help would be greatly appreciated

BLDC motors will probably give a sine wave output across the wire pairs. Try and measure the output with a meter. If there are only 3 wires, you can't go wrong. Is it a ground or a common wire to the other three ?

3-phase used-in-some-sort-of-factory probably isn't DC. Are you sure they're DC or is that how you want them?
