KV Series Quad Motor Control

The quadcopter drone (UAV) consists of a flight controller and four electronic speed controllers (ESCs), one for each motor.

The reference design uses a six-step communication process, including closed-loop speed control and dynamic motor current limitation.

The S32K142-MC24 is a reference design board engineered for general-purpose Brushless DC (BLDC)/ Permanent Magnet Synchronous Motor (PMSM).

KEA128-3-Phase Sensorless BLDC

This is an example of a 3-phase sensorless brushless DC (BLDC) motor control solution using a six-step commutation process.
