- Can you give me all the different types of DC motor its quite confusing coz some info says it has only 4 which is series , shunt , compount , and permanent magnet which is only under the category of brushed DC motors it doesnt include yet the brushless and the sub category however when you recognize or notice that in flowchart there are several like the one self excited etc I wonder if its an updated version though but I need you to list all of them and explain each and what category or subcategory I mean the overall DC motors even in chatgpt there are some added like universal , stepper , servo , coreless and so on. Explain each one. Pls help me if you could summarize or elaborate all at once so that it would be easy to identify or determine the overall information and additionally per category should have definition as well as the followingarrow_forwardAH ES 2arrow_forwardAnswer Letter C only.arrow_forward
