Somehow I lost the focus on this:
- First post: searching for: 48V 1000W DC instead of up to 90V / 15A
- Last post: 48 V with 150A -> 150A * 48V = 7200W ... ???
What is your skill level in electronics, motors and mechanics?
Pls tell us exactly what the actual requirements are. Are those 150kg the force which the robot has to deliver and has this value been measured, estimated or calculated, in other words: is that reasonable or a safety value?
And why can't you go with 90V? (Battery ?)
