Design of BLDC Sensorless Control System for Vehicle Fuel Pump

摘要：

This paper designs a kind of BLDC sensorless controll system for vehicle fuel pump. The control system uses 78F9222 of NEC as the core control unit, and uses Back EMF detection method to achieve the sensorless control for BLDC. The system can implement overcurrent protection, overvoltage protection and overtemperature protection. Loading test shows that the control system has high performance to meet the actual needs.
