I ask because I happen to be designing a BLDC motor controller, I am aware of using the back EMF to measure the motor phase, but never considered it as a force slowing the motor down. As a software engineer by trade I was hoping I could perhaps dynamically switch between the two control techniques to get low-end torque and high-end speed? I was also hoping to setup the controller to optimize the various parameters for the specific motor it is controlling by measuring the back EMF.
Any help is greatly appreciated :)
