[pstricks] part of an ellipse

[Goebel, Juergen]

Hi,

I'd like to draw only a part of an ellipse, that is an ellipse with an 
angle of 0 < phi < 360° (and with an arrow on one end for indicating
a rotating object). So I'm looking for something like the 
\psarc(n)-command, but for an ellipse. Is there a solution?

TIA

Jürgen

P. S.: Drawing an arc and scaling it with e. g. \scalebox{1 0.1} 
seems not to be a solution, because the linewidth is also scaled.
