L6258EA
so the gain of this block is:
where:
RL = equivalent resistance of the motor winding
RS = sense resistor
Because of the inductance of the motor LL, the load has a pole at the frequency :
Before analysing the error amplifier block and the sense transconductance block, we have to do this consider-
ation :
AloopdB = AxdB + BxdB
Ax|dB = ACpw|dB + ACload|dB
and
Bx|dB = ACerr|dB + ACsense|dB
this means that Ax|dB is the sum of the power amplifier and load blocks;
Ax|dB = (29,5) + (-31.4) = -1.9dB
The BODE analysis of the transfer function of Ax is:
