Hi,
depends what kind of motors you are using and what kind of control technique is used. There will be no issue to drive e.g. 1phase DC motors with available set of FlexPWM and eTimer modules. Driving 3phase motors require more resources.
MPC5744P has 2 FlexPWM modules with 4 x (2+1) channels and 3 eTimer modules with 6 channels
