This experimental study presents a precise speed
control scheme for Brushless Direct Current (BLDC) Motor which is fed
three-phase inverter implemented 150-degree commutation mode.  In 150-degree commutation mode, four rotor
position signals are required. From these four position signals can be attained
pure analogue rotor speed information. Because there are four position signals,
it can be easily obtained analogue rotor speed signal by implementing frequency
to voltage converter. So, low cost and further precise electronic
tachogenerator (ETg) can be put into practice in order to perform closed-loop
precision speed control for BLDC motors.

 

In this study, 150-degree commutation technique has
been applied a BLDC motor and four rotor position signals have combined
properly to attain higher frequency than one position sensor’s frequency to
acquire pure analogue rotor speed information. After converting four positions
signals to pure analogue rotor speed information signal by frequency to voltage
converter circuitry for manufactured this study, it has been applied to a PI
speed regulator in order to obtain constant rotor speed versus changing load.

BLDC motor driven 150-degree commutation has been run
under various loads and speeds and performance of the BLDC motor and ETg have
been examined.

Furthermore, a high resolution electro mechanic
tachogenerator is used in experimental setup in order to compare the
performances with proposed ETg.
