Cost Efficiency Study Comparation of PMSM and BLDC Motor

AI Thread Summary
To conduct a cost efficiency study comparing PMSM and BLDC motors, it's essential to first define the specific application and requirements for the motors. Understanding the operational needs will help clarify the differences between PMSM and BLDC solutions. Utilizing simulation software can facilitate the comparison of output parameters and material usage, making it accessible even for beginners. Resources such as textbooks and instructional videos can provide foundational knowledge on PMSM machines. A well-defined question and thorough analysis will lead to more meaningful insights in the study.

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?

Due to the application, you can use different excitation model and magnet shapes to have BLDC or PMSM ( sinusoidal or trapezoidal back EMF)
I had a similar project and I used a simulation software to compare the output parameters and material usage. It was easy to use for me as an amateur. You may find it useful to test EMWorks studio or [Redacted by the Mentors]. No need to have deep knowledge in finite element to use them.

There are some useful textbooks about PMSM machines, I used Dr.Hendershot book and videos to learn the basics of these machines.
 
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
Thread 'Electromagnet magnetic field issue'
Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...
Thread 'Beauty of old electrical and measuring things, etc.'
Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
