Thanks for giving me the right search term! I went down the road of H bridges and then half bridges and then I found this excellent guide!

Ah, thank you this is exactly what I was looking for!

Sorry, I worded that poorly. I do understand that the motor becomes the generator In terms of scale, I'm thinking about E-bikes/scooters territory but I'm curious in general. Really, I'm just looking for a guide about the circuitry for regenerative braking.

Hi Dave, Ok, I think I see what you are saying. By sending the voltage from the generator to the battery in a PWM style, we can effectively control the load on the motor. Where is the voltage going during the off periods? Back to the motor? Also, if you have any books or guides, I'm more than...

Ah ok, this makes more sense. Follow up question, Does the regenerative braking circuit split that current between going back into the motor and into the battery? If so, is maximum braking force when all of the current goes back into the motor and minimum braking force when all of the current...

Lately, I've been reading about the electronics required for driving motors and naturally that transitioned into braking. I think I have a decent grasp on resistive braking but I do not fully grasp regenerative braking. This plus googling gaps in my knowledge have been my primary sources...

Good news: The capacitor finally arrived! Bad news: The capacitor is not the issue D: The moment I plug it into the wall the amp meter shows a short in the system. I'm pretty sure one of the windings in the motor has melted. I'm going to try to get some free time in the next few days to tear...

Agreed, 340-408 is what I used in the Grainger search and that is the product I chose.

Wow, a lot has happened since this morning. I went outside and checked over the capacitor again and took some better photos. - Photos: http://imgur.com/a/TvQzC - Writing on the capacitor: 340 -409 MFD - Capacitor Sizing Calculations...

Hey guys, I need some help with replacing a blown capacitor. I've linked below to the machine we are working with, Penagos k-60. I'm not able to find any documentation on the capacitor. The one we took out of the machine today is so old that we aren't able to see any of the writing and it's...

You'll have to do a lot of searching on google, you can get started here: http://andrew.gibiansky.com/downloads/pdf/Quadcopter%20Dynamics,%20Simulation,%20and%20Control.pdf Personally, I wouldn't recommend making a quadcopter from scratch but instead buying a kit and slowly make adjustments as...

Welp, I just found my mistake. Damn Radians!

X axis: -9545.026 -> http://wolfr.am/18Pi697 Y axis: -4164.957 -> http://wolfr.am/17Ljn44

Homework Statement An infinite line charge of uniform linear charge density lambda = -3.1 mu or micro CC/m lies parallel to the y-axis at x = -1 m. A point charge of 0.7 mu or micro CC is located at x = 2.5 m, y = 3.5 m. Find the x- and y-components of the electric field at x = 3.5 m, y = 3.0...

Thanks guys! It makes sense now.
