How about the capacitors? I would figure the capacitor would be connected to the M- bar to filter out motor's inductance voltage ripple, but they are on the B+ bar, what is their purpose? Are they just providing an average stable voltage to the motor? If so the voltage on the B+ bar has to go all the way back to the battery and then to the motor. Wouldn't it be better to have the B+ bar also be the M+ bar on the other side on the controller to get the maximum effect of the caps?
Also, if the diodes are to smooth voltage to the motor, what is filtering voltage spikes coming out of the motor and hitting the diodes?
Please don't take my questioning offensively, I am just curious and trying to understand the design better.
Adam,
I am located in Fall River, MA. Thank you for the information about the diodes, so as long as i have them all equally heatsunk they should be fine.
