Over 1 HP they pretty much always three wire.
1HP and below, could be either two or three wire. You really need to know motor info to match the controller to the motor if it needs a controller.
You could verify continuity between all three leads if uncertain. Two wire motor should have a conductor that is open though it may have kohm or mohm reading to the EGC if the free end is not sealed and submerged below water level.
