The Switching Time Research of BLDCM for Fuel Pump

2018 2nd IEEE Conference on Energy Internet and Energy System Integration (EI2), 2018
The brushless DC motors for Aviation fuel pump use Hall position sensors to get the position of rotor in motors. The rotors' switching time would be advanced or delayed because of the angle error in Hall position sensors. In order to ensure the motor run reliably, the switching time has to be determined accurately.
