Hi,

Just trying to understand the closed loop torque mode implementation of the controller. I've read that when using Torque mode with a sensored BLDC motor it actually uses FOC control, is it so?

Can this be explained please? I'm using FBL2360. In torque mode the manual shows a simple torque configuration i.e. Torque Command>>PID>>PWM>>Motor and then current feedback like this .

But in FOC section you have given the following detailed block diagram.


So which implementation is it? If it's the simple one then can a detailed block diagram be shared with Torque input ref to the controller and the feedback. Will appreciate any support on this.

Just to add, the the motor has hall effect sensors connected to FBL2360, the controller is set in Trapezoidal mode. So if anyone can help explain the torque mode implementation with these settings it'll be much appreciated.
