Part Number: TMS320F280049C-Q1

hi,

I am implementing FOC algorithm for sensored BLDC Motor.   I am not using Speed Loop.  i am using CT for sensing of output current . I am doing CLARK and PArk transformation. Dq is feedback to Torque PI loop. Throttle will give torque command to the FOC and refernce for Torque PI  Loop.

Am I doing right or wrong ?

At no load on Motor  For min. throttle value speed is get increasing .

what should be current Iq graph?

How to implement torque mode w.r.t. throttle Input ?

Also want document to understand trajectory functions.

Regards,

    It's right that's the generic FOC technolgy.

    That's normal if the motor is running without load. The Iq value is related to the motor and the load.

    As above, that depends on the system related to the motor and the adding load.

    It's similar as a ramp control. You might find its source code in the motorControlSDK that could be easy to understand.

    You may take a look at some of motor drive textbooks if possible that could have more details about these you want.
