Now is this at 12V or 10V :) Bobby=20 -----Original Message----- From: Rotary motors in aircraft [mailto:flyrotary@lancaironline.net] On Behalf Of Ernest Christley Sent: Thursday, August 31, 2006 9:59 AM To: Rotary motors in aircraft Subject: [FlyRotary] Re: EC2 Current Requirements There are two important issues being mixed together here. One is the max current, which is important for sizing wires and fuses. The second is typical running current, which is important for sizing alternators, batteries for alternator-out running time. I think we have it all, but let's see: Running@6000RPM Surge EC2 .25A .25A EM2 .25A .25A Each Injector 2A 5A Each Coil 2A 5A I've designed in quite a bit of electrical dependancy, so the alternator-out running time has me concerned. With all injectors and coils on seperate switches, it should be possible to extend the range by switching off a set of injectors and the trailing coils, and accepting reduced power. Does that sound viable? --=20 ,|"|"|, Ernest Christley | ----=3D=3D=3D<{{(oQo)}}>=3D=3D=3D---- Dyke Delta Builder | o| d |o http://ernest.isa-geek.org | -- Homepage: http://www.flyrotary.com/ Archive and UnSub: http://mail.lancaironline.net/lists/flyrotary/
