KV Series Quad Motor Control

KINETIS-DRONE-REFERENCE-DESIGN

Roll over image to zoom in

The quadcopter drone consists of a flight controller and four electronic speed controllers (ESCs), one for each motor. The flight controller is equipped with a radio to receive flight commands from the pilot and the inertial measurement unit (IMU). This reference design combines four separate ESC boards into one controlled by a single KV4x or KV5x MCU, and is capable of driving four BLDC motors.

Features

  • MCU
    • One KV4x or KV5x MCU capable of driving four motors for electronic speed controller.
  • Drivers
    • Each inverter is enhanced with an GD3000 pre-driver that drives only N-channel MOSFETs for better efficiency.
  • Sensors
    • The IMU uses the internal accelerometer, gyroscope, magnetometer and GPS receiver to provide information necessary for autonomous vehicle stabilization.
  • Monitoring
    • Easier debugging and real-time control with FreeMASTER run-time debugging tool
    • Software features such as diagnostics, logging and estimation of the remaining flight time based on current consumption
