Motor control library provides implmenetation of various algorithms to support below features :
- Advanced Features
- Supporting Rotor Field Oriented (RFO) control
- Supporting Stator Field Oriented (SFO) control
- Supporting Trapezoidal or Block Commutation (TBC) control
- Floating Point Base
- GUI Integration : Easy monitoring and configuration of the various motor control parameters can be done via GUI
- Configurator view
- Test Bench view
- Tools such as Oscilloscope, Motor Profiler, etc.
There are three major control types that are supported, namely
- Rotor Field Oriented (RFO) control
- Stator Field Oriented (SFO) control
- Trapezoidal or Block Commutation (TBC) control
These control types are selectable as build configurations (via Make variables CTRL_METHOD_RFO, CTRL_METHOD_SFO & CTRL_METHOD_TBC ).

- Motor control library supports 25 different permutations of control type, control entity, feedback type, and statup method as shown in the table above.
- In addition, both three-shunt and single-shunt configurations are supported, which result in more flexibility in supporting various applications.
- It should be noted that the user will have flexibility to include or bypass the current loop when using TBC in BC mode.
- Bypassing the current loop can address low-cost BLDC applications with no shunts or ADCs.
Detailed information on supported toolchains (make variable 'TOOLCHAIN'), kits (make variable 'TARGET'), Hardware setup , Software setup, creating project in ModusToolbox with all the other assets for a particular kit and code example etc. are available in the README file of MOTOR_DEMO Code Example.
