Thanks, and another question
,
I have mentioned about the pattern of PIC outputs (or IR2130 inputs) at a previous message.
I changed the pattern as below:
H1-L1: 111111111111000000000000000000000000
H2-L2: 000000000000111111111111000000000000
H3-L3: 000000000000000000000000111111111111
When I apply this pattern, the motor worked more unsmoothly maybe a little slower;
Then I tried this:
H1-L1: 111111111111111111000000000000000000
H2-L2: 000000000000111111111111111111000000
H3-L3: 111111000000000000000000111111111111
and when I applied this pattern, faster and maybe a little smoother than previous one.
As you mentioned in your post, as far as I understood, we cannot change the torque,
because our voltage supply is 60 VDC, but I think small changes on speed happens by
changing the input pattern to IR2130. How can I make the speed more smooth and fast
(maybe a little sinusoidal)? I mean what kind of pattern can help me?
Note: The original program makes it smoother and faster than mine.
Note2: The patterns I mentioned above is a period which is applied 3 times in one second.
Maybe changing the frequency may help something, I should try it in the morning
.
Thanks for helps.
