This paper introduces a design of brushless motor control system in portable ventilators, which is based on ML4425 and C8051F330 microcontroller. For the simplify-cation in circuit design and programming, this is very suitable for portable ventilators. In the design, the ML4425 motor controller provides all of the functions necessary for starting and controlling the speed of delta or triangle wound brushless DC (BLDC) motors without sensors. And the microcontroller is responsible for much less tasks to improve real-time performance. With the detailed explanation of step-by-step implementation, the design is able to provide significant efficiency improvements, lower acoustic noise and better reliability.
