    Four-quadrant operation and inversion may need only one motor. To run the machine as a motor in the direction with positive speed and torque in quadrant 1, to run the machine as a motor in the opposite direction with negative speed and torque in quadrant 3, and operating the machine as a generator, so that power is returned to the power supply, the converter then ‘inverting’ power rather than rectifying, and the system operating in quadrant 2 or quadrant 4.

    As you referenced forum, every motor is connected to a LAUNCHXL-F28027F + BOOSTXL-DRV8301, and the shafts of these two motor were connected by a coupling. It just used one motor to pull another one to the opposite direction to demo four-quadrant operation.
