Induction motors are perfect for applications powered from an AC fixed frequency network (400 Hz). They are controlled from a simple contactor and no electrical drive is needed. This makes them very reliable compared to a DC brushless motor and its associated drive.
A separate drive may be used for variable frequency networks when load characteristics and system needs require some speed variation during use.
No wear (except bearings). Reduced number of components because there is no ON/OFF switching
Design works well when the torque is a monotonously growing function of speed
