Simpler off-the-shelf brushless DC (BLDC) motor electronic speed controllers (ESC) for UAVs employ simple back EMF techniques to control the multi-phase motor. Kinetis V Series, because of its precise timers and ADCs, are able to cost-effectively provide Field Oriented Control (FOC) where each of the motor phases are monitored closely to provide more precise and efficient operation.
The addition of a CAN-bus to an ESC enables proper closed loop feedback, and can be used with protocols like UAVCAN to give advance warning of any motor degradation, overheating or damage back to the main flight controller.
Encoder inputs are supported in Kinetis V, and while not typically associated with high speed UAV BLDC motors, they can enable many other robotic, automation or actuator motors.
