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. <o:p> </o:p> <o:p>  </o:p> 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. <o:p> </o:p> 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. <o:p> </o:p> Furthermore, a high resolution electro mechanic tachogenerator is used in experimental setup in order to compare the performances with proposed ETg.  <o:p> </o:p> }, number={1}, publisher={ISRES Publishing}
