2013 Leaf integrated e-powertrain a smaller, lighter package

Thu Apr 11, 2013 6:06 pm

From the SAE website:

"For the 2013MY Leaf, Nissan integrated the motor, inverter, and charging unit into a single stack under the hood, freeing up space and reducing mass."

Reading that article I couldn't help thinking about the ip/patents Nissan must be racking up. Between Nissan and tesla other manufacturers should be concerned. For some reason I doubt they are though.

The page has changed slightly to include 4 pics instead of the original 1.

See http://articles.sae.org/11993/ vs. the an old snapshot at http://web.archive.org/web/201312030808 ... org/11993/.

Interesting motor sims of the Leaf show efficiency rising up to 100nm. So maybe you can be too light on the accel pedal after 1000 rpm.

But not below 300 rpm where efficieny is near zero. Support legislation to legalize rolling stops.

This motor features a nice three element interior permanent magnet motor showing very clean flux lines with minimal wasted heat in eddy currents.
