Question about Modeling of RC BLDC Motor..
« on: May 13, 2019, 11:53:30 am »
Hello, EEVBlog Users !

Always Thanks you for your time and convenience.

I am looking for information to modeling transfer function of RC BLDC motor.

Actually, I found one paper in IEEE Xplore. but, transfer function and procedure was too simple.
and I couldn't find more detail paper.

If you don't mind, could you recommend to me good book or detail paper to modeling transfer function of RC type BLDC motor ?

Please, let me know !

Why do you think the model is too simple? DC and BLDC motors do not have a complex electrical model. The complexity lies in the drive system and your drive strategy.

You say "RC" BLDC motors, so I suspect you are looking for sensorless drive. This needs a special controller with startup functionality, and you will only be able to start the motor with limited mechanical load (eg, a propeller).

Hello, Mr. Benta !

Thanks you for your time !

I think, I thought more than necessary about BLDC. I mean, I guess My brain has filter that make simple things to difficult always. because, I already know structure of sensorless BLDC motor.

Thanks you for your help Again, Mr. Benta. I appreciate it.
