Hi there! i have been researching for weeks now and i have some problems with respect to BLDC motor control :
The university has provided me with a MOOG BLDC, 330V motor. IC=6A, RMPmax-6000
Now the motor comes inbuild with a resolver, yet i am struggling to find papers or methodology on utalising this analugue data to determine rotor position.
Given that the motor is so old, i dont even know if they would have aligned the resolver, or whethere the BRAND contorol system accounted for this..
Are there any other ways i can control this motor ? with or without the resolver. Also once i mount the apropriate gear on the shaft there will not be rool for me to attatch a position encoder.
the application is to build an electric Kart, capable of reacking 70km, after my touque and acceloration cals i believe this motor can achieve at least 60km , and well it was free so i cant argue lol. Its just the methodology for a) finding and monitoring the rotor position! and b) using this to co-ordinate the correct commutation sequence.
the university has permitted me to buy the an invertor and microcontroller for this, and im not to worried about the PWM or coding, just how to get the positioning. I guess i dont need micron accuracy as in a cnc machine, but getting max torque via aliging the rotor flus and startr current at 90 degs would be desirable...
can anyone help me out her ? or recoment ways i can achieve my goals in this project
cheers!
