You can control speed. Torque depends on the load. Of course, for a given motor there is a maximum torque, which is related to the flux and the armature current.

i am using the motors for automotive application. Then i also have to control torque for maximum efficiency and better acceleration. How can this be doneAre you sure? This action cannot be undone. -

Subject to the maximum torque possible for the particular motor control the armature current.Are you sure? This action cannot be undone. -

thats what some controllers do.They either control speed by controlling voltage or control torque by controlling armature current. But how can i control both at the same time so that power can be maximizedAre you sure? This action cannot be undone. -

Are we not missing something here? Each motor has a maximum power output that cannot be exceeded.Are you sure? This action cannot be undone. -

yeah but what if its operating at a lower power for a given speedAre you sure? This action cannot be undone. -

If the speed is maintained, the current will match the torque produced.Are you sure? This action cannot be undone.
