Thank for the article "2013/12/13/art-of-stopping-the-motor-vm-pumping" which is most interesting,
Is there useful guideline to consider sizing of buffer capacitor to limits voltage.
I have 3 phase generator (24V) with 6 diode rectifier so generator will not absorb energy since the diode block these current.
This leave capacitor to do the work. Due to space constraint, is there guideline to work out minimum sizing of the capacitor that sufficient to avoid risk of break down voltage in the circuit.
The Motor in question is 4 pole BLDC, maximum 50W power. It is used as servo actuator (or CNC) with screw.
I'm using F28335 as motor controller, (cannot use instaspin or F2803x).
