for sucking purpose you need much more apart from motor
more info is required like weight of ball, distance from which to suck ....... etc

sucking requires large amount of power , more the distance the power required goes up exponential. Also you might need to look into BLDC motors with very high RPM.

Anyhow give more details ? distance , size weight etc if building for a competition give link . I think there must be a better way.
