Hello everybody and thank you always for all the help.
I am starting a project on brushless motors. Now, I have worked in the past with brushed motors (or DC motors using H-bridges) and with steppers.
I have no experience with brushless motors so I am now researching. (If any of you have a link to a good tutorial , very welcomed)
My question is- and it can be totally ignorant sorry- is, suppose I am controlling the motor already and it is turning at some speed. How can I see at which speed it is turning? Do I need a sensor? What is a Hall IC sensor?
Also there is a schematic element I dont understand. See page 24 of

in Motor Internal Connection Diagram you can see on pin 2,3 and 4 some element in the schematic . What is it??
Thanks a thousand for any help or advice.
