Abstract—This paper presents a new 12-step sensorless drive for
brushless dcmotor based on back-electromotive force (back-EMF)
differences, which are estimated the disturbance observer
(DOB) structure. Availability of rotor position information with
a resolution of 30° and commutation without phase shift are the
advantages of using the back-EMF differences. Unlike the conventional
methods that obtain part of the back-EMF signal the
manipulation of three phase voltages, the proposed DOB structure
can access the entire back-EMF profile. By designing a proper
low-pass filter in the DOB structure, the back-EMF difference can
be well detected with lower sensor noise. Compensation of delay
commutation introduced by the filter is also discussed. Experiment
results showed that the proposed sensorless drive is capable of running
themotor in lower speed, and performs better under different
speed and load torque as compared with the conventional method.-Abstract—This paper presents a new 12-step sensorless drive for
