hi i have two different systems (i have tried to upload them but they both exceed the size of the upload limit). One is a dc motor block diagram (it has a PID at its controller) the other is a bldc motor model with a PID controller input. The block diagram of the DC motor consists of an armature block a load block this is where the angular velocity is produced at the output of the load block and if the angular velocity is integrated it provides me with the angular position, there is also a back emf from the velocity. The BLDC model has a contolle then has the BLDC T.F. this is where the angular velocity is produced and therefore when integrated gives the angular position. My question is how comes for the BLDC system why does it no need a load block which provides the inertia, which then generates the velocity by divding the torque generated from the motor?
