I do not see, if the IC has included (buildin) the diodes.
THB6064 included buildin the diodes?
Why would anyone in their h-bridge design include diodes?
Why desiden others that are not important?
Using them Prolongs transistor ?
Do not use them, gradually deteriorates transistors?
Do not include a way to slowly deteriorate the circuit, so that at some point the customer having to buy another?
Exactly what happens and we're talking about?
Well I do not know much about electronics,
I read a bit, and then hise some calculations:
With 3Amp motor and 7 mH.
Time off transistor, switching transistor Output characteristics (time tf)
TB6560 is 1.0 ms = 0.000001 sec.
TB6600 is 0.5 ms = 0.0000005 sec.
The spike volt = H * A / sec.
With TB6560 = 0.007 * 3 / 0.000001 = 21,000 Volts
With TB6600 = 0.007 * 3 / 0.0000005 = 42,000 Volts
Please review these calculations, it could be a mistake.
I do not know whether that voltage is enough to make a arc.
I do not know how to calculate the duration of the peak,
I would like to know how to calculate it.
Also like to know how to calculate the peak current (ampere).
Maybe then I could choose a diode or decide not diode.
What is the best diode for this?
How as you do for deciding not to install diodes?
you, as you do?
I wish I knew.
My doubts are multiplied exponentially. -LOL-
