Hello, I've read through everything I could find on rear diff setups, however, most have been using motors with low RPM capabilities, along with being quite dated (2008).
The following are the current specifications for my project: *Motor* Max. RPM: 10000 Peak power (kW): 170 Peak power (Nm): 250 *Rear Diff IRS* Ratio: 3.27 The motor efficiency is at the higher end of its performance curve. That being said, if the vehicle is traveling approximately 80 MPH and the wheel is spinning at 3000 RPM with 28.7" tires, where does that leave the motor's RPM? Would it be the wheel RPM /multiplied /by the diff ratio? 3000 * 3.27 = 9810 RPM? Or would it be the wheel RPM /divided /by the diff ratio? 3000 / 3.27 = 917 RPM I'm trying to verify where my motor's RPM would reside along its respective curve. Thank you in advance, Forrest Walker Whitmore -- Sent from: http://electric-vehicle-discussion-list.413529.n4.nabble.com/ _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub ARCHIVE: http://www.evdl.org/archive/index.html INFO: http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
