Dear all ,
I am using PIC16F1938.I have used Mplabv 8.86 for coding with hitech compiler v9.86.
I need simple favor implementing this code in timer interrupt.
I have excel sheet attached for reference.
I have overload trip of motor setting 30A with Trip Time 30S. i would like to achieve attached curve using timer interrupt. can someone guide me how it can be implemented.
user can change overloadtrip and timing accordingly.
curve is meant to achieve below function
Lower current higher trip time and higher current lower trip time
Motor is: DC, BLDC, AC 1 phase, 3 phase or anything else?

* RMS_current represents the heating in the winding, in either case.
* Usually with motors one takes I^2t overcurrent limiting algorithm.
--> this means if you do it this way you don´t need to take the square root of the current. (which makes processing more fast and easy)
