JVN tabs question
What is the difference between the "intake mechanism" tab and the "linear mechanism" tab. I get the same travel times but the current draw is a LOT LOWER on the linear tab.
I am trying to use it for our winch. |
Re: JVN tabs question
To calculate a winch, you would use the Linear Mechanism tab. The Intake Mechanism tab is for calculating intakes used to pick up spherical objects from the floor.

THANKS It will go a lot faster now

Re: JVN tabs question
I don't completely understand. Why would the intake calcs show a much higher amp draw?

Drag load =/ Applied load

You can also use the rotary mechanism tab but then you have to calculate the number of rotations required to climb. |

I think Eric meant the not-equal-to symbol, =/= he just forgot that second =.

Re: JVN tabs question
The intake tab is for calculations for a conveyor sliding/rolling a game piece and the linear motion tab is for a winch moving a linear mechanism.
The linear tab uses load applied directly to the winch and the intake tab uses drag load of the game piece. It doubles the drag load number for the calculations. Maybe to account for the fact that a rolling game piece is moving half as fast as the conveyor? Maybe for safety factor? I'm not exactly sure. |

OK I get what you are saying but it DOUBLES the current draw and I would think a rolling game piece would reduce the current draw. |

I suspect sticking a 150lb ball into an intake roller is going to present some different results than using that same roller to winch up a 150lb robot, whatever the case may be. If you want the correct answer to the question of what that tab assumes, I suspect you might have better luck PMing JVN. |
