Re: gEDA-user: Non-linear spice models for power sources operating near stall

Turned out that the mechanical coupling coefffient is so low that a stall cannot occur. So Matthew W.'s #1 approach will work for me. Thanks everyone for the help! Mike On Wed, 2010-06-02 at 20:13 +0200, Armin Faltl wrote: > > Mike Crowe wrote: > >>3. More complicated models would vary th

gEDA-user: Non-linear spice models for power sources operating near stall

Hello Somewhat off topic, but I am working on an energy harvesting device which uses a small generator (<100W). I am looking for a spice model that I can use as a template to create a model for the motor dynamics near stall. Can anyone point me to a good starting point? Thanks Mike __
