The torque generated by a PMSM by, is the (positive) magnitude of . If we control the angle  such that  , hence ,  then the PMSM becomes a Field Oriented Control BLDC motor generating the torque as .   On the other hand, the torque generated by a separately excited dc motor can be expressed by  (refer to lecture notes).   For permanent magnet DC motor, .
