BLDC Motor Control Based on Duty Cycle

High Speed brushless DC (BLDC) motors are commonly used in quad-copter rotors, drones and in radio controlled systems. Micro controllers are commonly used to control such BLDC motors. However programming a micro controller requires understanding of an assembly language and the limited memory space available in a micro controller limits its use for various applications. Raspberry PI is a single board computer which operates at 5V. It has very wide applications in the area of robotics and automation. In this work, the control of a BLDC motor using a Raspberry pi system is detailed. Programming is done using Python language. PWM technique is adopted for programming to control the Electronic speed controller which in turn activates BLDC with power from LiPo batteries.
