Cost Efficiency Study Comparation of PMSM and BLDC Motor

[sambbal]

I want to do a study comparation of PMSM and BLDC Motor. I want to analyze the cost efficiency if BLDC were subtitute to PMSM. Where should i start? what kind of data that i need?

This sounds kind of meaningless without a careful definition of the application. Each of these motors is the best choice for something, yet they are not the same. I doubt you'll get much guidance here without a more detailed description of the constraints in your analysis.

So, the first step is to ask a good question, not of us, but for yourself. What do you need the motor to do? Why? What would a PMSM solution be? What would a BLDC solution look like? How do they compare?
