I have 50W 4 pole BLDC Motor as used for servo acuator (or CNC) with screw.
I have 3 phase generator and 6 rectifier diode with provide 48V under steady rpm.
I wish to calculate sizing of the capacitor in case of motor slow down (reversing torque) or estabishing braking. Is there guideline to do that. The cap sizing is critual due to space constraints.
I know that current pumping into generator is impossible due to rectifier diode which work only for forward current, so capacitor bank play important role to limits voltage from approaching breakdown area.
