SIXTEEN leads? Are you sure it is even a motor? Could it be a
motor with encoder? That might begin to make more sense. I can
imagine a differential encoder with index having 8 leads. Make it
11 if it also has commutation channels for a brushless drive.
3 more for a 3-phase brushless motor, any you only have 2 left
to worry about. Possibly a frame ground, or a tachometer.
You could hook a scope up and turn the motor. if you get slow sine
waves out of it, those would be the motor windings.
