Which motor run in both direction?

Trick question: all motors do if you invert the polarity of input.

Not a trick question! In the case of d.c. motors, for example, you have to reverse the polarity to either the field or the armature -not to both. If you reverse it to both, it makes no difference to the direction of rotation! For a three-phase induction motor, you must interchange any two line conductors.
