At present, the most obvious trend in the field of motor drive and control is to adopt the brushless dc motor (BLDC) motors, but considering the design into a BLDC, motors have to seriously consider the reason for doing this, through integration of upgrade, BLDC motor and drive motors system, can greatly reduce the cost of both sensor and no sensor BLDC motor drive motors, the main consideration is the reliability, audible noise and the overall efficiency,

Server the cooling fan, exhaust fan, no hakaze fan, and other three-phase brushless motor control applications are need to choose a suitable driving chip to control the fan,
Hardware engineer mainly choose what plan now?
