Long battery wires will kill ESC's over time! Extend motor wires
All controller manufacturers and EE experts say the same, long battery wires will kill ESC's over time! Extend motor wires instead of battery wires. If you cannot but extend the battery wires you have to add extra ESC input capacitors.
ESC manufacturer and EE expert statements (in unison), workarounds, rules of thumb, capacitor types, 'watery' explanation, theory: http://www.rcgroups.com/forums/showt...highlight=kill Contents
Excellent thread by someone who apparently is into controller and/or power supply design. Explanation, considerations, capacitor choice, capacitor sources, albeit with a slight e-bike slant: http://endless-sphere.com/forums/vie...p?f=30&t=22194 Vriendelijke groeten  Ron• diy motor tips • Drive Calculator • • diy motor group • Cumulus MFC • Last edited by ron_van_sommeren; 10-15-2011 at 08:38 AM. |

Re: Long battery wires will kill ESC's over time! Extend motor wires
A problem not mentioned is the DC switching current rating that the caps are rated for, this is a big issue not addressed by the article. If they are underrated and are switching more current than they are rated for they will go bad. This is part of the long wire issue. A quick check is if the caps are getting warm(thermal rise while running).The longer the wire length the more DC switching current the caps are subject to. IR losses at work. The ESC vendors cut corners for cost so we can buy cheaper and with it comes a price.

Re: Long battery wires will kill ESC's over time! Extend motor wires
Ron,
What are your thoughts on installing a resistor on a seperate power lead to prevent that lovely "SNAP" and electrical arc when you plug in a pack to the esc on a big system, to prevent damage to the electronics?

If you don't want to diy the capacitor unit
