Proteus help

[kulanga]

Hi
I need help with Proteus 7.4 about how to connect AC induction Motors with the variable speed drive.I searched for the Induction motors and found BLDC-star,and BLDC-triangle, and connect(BLDC-star) it with my simulated VSD but it didnt work,,, but i have only the mobile vesion of proteus 7.4 which doesent have help file.....

SO I need a simple help about how to do it in the Proteus that I can make simulation for my whole circuit

Can you try unipolar stepper motor, for incase to see if you will get an output. I used it in my project. check page 45 on the attachment.

thanks

thanks for ur valuble information, i am going to moddle a VSD using proteus and i wana know whether the proteus have induction motor modle or how 2 use BLDC-star,and BLDC-triangle, in proteus 7.4

When you post a thread, try to make sure that you avoid usage of abbreviations because we can interpret them in different ways. For instance, I do not understand which VSD moddle you’re talking about. Can you explain and I would like to help you if I can.

WTF is the point of that post??

k sorry lambohang
so yea Variabe speed drive which changes induction motor speed by using 6 IGBTs(Insulated Gate Bipoler transistors,,which act as switches).. if i explain the drive first it converts standerd AC supply to DC by 6 diode bridge and then the DC is converted to variablefrequency,variable voltage (by using Pulse width modulation) supply to the induction moter by switching the IGBTs)
I just wanna modle this befor making it ..pl help

Hi Kulanga can you post the circuit where you connected BLDC-star and the code. that would be helpful because we can be able to
see where corrections have to be made. For instance look at my circuit diagram on the attachment and the code I used to run the program.

Hello! I am building an incubator. I am posting here because in my thread no one responded, maybe it's because of the title. I have created the biggest part of my code so far, but I reached the point where I really need some help! I need to turn the eggs every 8 hours. I configured TMR0 to give me an interrupt when 8 hours pass, but I don't know how to control the motor. I never worked with motors before. I am thinking about using a DC motors with Hall sensors to make it stop when it has reached the limit of tilting the racks with eggs. I need to tilt the racks 30 degrees up and 30 degrees down.
This is also a project for my college so I am supposed to do it in asm. Here is the link to my thread :https://www.electro-tech-online.com/threads/full-option-egg-incubator-help.114276/#post941001

I tried implementing some asm code in my project but I got so many errors I didn't know where to start.
I also need to control 2 fans, that is like controlling 2 BLDC motors, so i need all the help you can give me.
If anyone needs help with the comment just say, and I will translate them.
Thanks in advance!
