【Abstract】Traditional brushless DC motor control methods usualy require the use of sensors to measure the rotor positionand speedof the motor.However，theuseofthesensors increases thecomplexityandcostof thesystem.Based onthis，this paper proposes athrotle control method basedon transducerbrushless DC motoris proposed，sothat the motorcan achieve accurate throtle control without thesensor.This method is basedon thein-Fand current information of themotortoitsderipositionand modeling.First，themotoriscalculatedusingthecurent information.Then，therotor positionofthemotor isestimatedbythewaveformcharacteristicsand thecurrentinformation.Finally，therotorspeedof themotorisobtainedbydistinguishingtheestimatedvalueoftherotorposition.Basedontheobtainedrotorpositionand speed information，the throttling control of the motor can be achieved.
