Claim 0:
1. A transmission for a vehicle, comprising:
a transmission unit for receiving a transmission command for a vehicle;
a driving unit for generating a driving force for switching a posture of the transmission unit; and
a controller configured to cause the driving unit to switch the posture of the transmission unit based on whether a preset condition is satisfied,
wherein the driving unit comprises:
a first stator for generating magnetic flux;
a first rotor including a first inner permanent magnet and a second inner permanent magnet, wherein the first inner permanent magnet and the second inner permanent magnet are disposed axially with a predetermined axial spacing therebetween along a rotation axis, the first rotor being configured to be rotated by the magnetic flux transferred to the first inner permanent magnet;
an outer permanent magnet provided in a number different from a number of the second inner permanent magnet; and
a second rotor configured to rotate along a magnetic force path between the second inner permanent magnet and the outer permanent magnet at a number of revolutions per unit time that is different from a number of revolutions per unit time of the first rotor.
