Please I need help on speed control of 3phase motor using thyristor.
Whit these Descriptions:
Three Phase Fully Contolled Bridge Rectifier (6 Thyristors)
Change the firing angle using 6-pulse generator.
Voltmeter is used for measuring phase voltages.
Multimeter1 is used for measuring voltages across all the 6 thyristors.

Hi Sina
First of all i need to say that name of your thread and the question which is inside are different . why ?
You said speed control of DC motor and then you have asked for a three phase motor control via thyristor !
I suspect it is some sort of final project isn't it ? and i hope you are not expecting that someone give you all of the things specially red paragraph in a map and you just build it !!!!
Anyway . i can guide you to design it . first mention the required power ( current and voltage ) and type of your nominal load . and ask what is your exact problem , then i'll guide you . furthermore , why SCR ? why not IGBT instead which can be much better here ?
i want to simulate shunt dc motor but i don't know how change the dc machine in matlab to shunt dc motor!!
i put ground as you told but the result didn't change!!
i think this site have lot of expert in power electronic but i find out most of them are amateur...
finally i myself find the problem and solve it.
some so-called expert thinking that it's my final project and i can not do it!
