Dc machimes are designed like that angle betwean the stator flux and rotor flux is 90 degree to produce unidirectional torque

Answer / umesh

The torque formula for dc motor is T=k(current * flux)
The commutator with brush converts the dc into ac which produces alternating flux.It means both armature current and flux are positive or negative at the same time.
