country.All the key technology needs to be
solved.Motor and its
control teelmology is
one
ofthe most important teeimologies that must be solved firstly. Firstly,this paper inla'odueed the status ofEV investigation and
development.Comr舳xt
with several types ofmotors which used for EV
BLDC in-wheel motor is
one
it啪be found that the permanent magnetic
of the best drive molots for EV'and this motor has good
foreground.In the second chsptcr the theory and math model of BLDCM is introducdl.and the key problems of drive and control of proposed.
.
BLDCM is expatiated,and
rational
project is
7,Secondly,this paper introduced the hardware and software ofthe lIloto/"control system.
Bring out the

the speed of the

.Thirdly,the paper presents research work strategy,which involves
on
BLDC in-wheel motor叩leed control
PWM modulation
and close-loop印lecd contr01.The dual pDl盯
driving method for BLDC in-wheel motor is emphasized.This the maneuverability and response ofmotor better, Lastly,On.the basis of the foregoing
