Brushless dc motor is the core part of many technical products, covering various high-tech fields such as transportation vehicles and industrial equipment. Compared with traditional control methods, FOC has the characteristics of high efficiency, low noise and fast response. Therefore, FOC algorithm has developed rapidly in recent years.This paper mainly proposes an algorithm to control the brushless dc motor. Through the frame design of the brushless dc motor control system, it tries to use STM32 to achieve the FOC drive control panel, and then deduces the main formula of the FOC control algorithm. The brushless dc motor is controlled by FOC algorithm, which not only avoids the shortage of the traditional brushless dc motor control algorithm, but also improves the operation efficiency of the motor system. In addition, FOC combined with sensorless algorithm improves control efficiency, reduces process cost ...
