    Is there a connection from one side to other?

 Hard to say.
 Any other markings?
 Makers name/data plate?
 AC motor or DC?
 Is it known it ran off AC?
  (Sometimes power rectifier is buried inside instrument).
 Any idea of RPM (centrifuges can be FAST.

 There ARE, tho hard to find, industry standards (recommendations)
 for wiring colors.

 At a GUESS its a series (universal) motor, IF so:
   Yellow to line
   (other) Yellow to Red
   White to neutral.

 Use care, if trying.  Wait for more advice.
