Re: Jaguar current sensing technical details?
Two additional sources of error:
Brush commutation on the motor The current shunt resistor is on the supply end of the H-bridge drivers; it is not subject to the motor impedance, because it is cut off from the motors when the FETs are in the OFF state. What would the current through this resistor look like over a span of 200 us? (That is, 3 pulses at 15 khz)
