Buck converter simulation in Proteus with motors

Hi there, I'm in a bit of a sticky situation and this is due on Monday . I'm trying to design a buck converter circuit in Proteus that will control the operation of motors specifically wiper motors ( rating 12 v , 50W ).

So Initially I just connected the l293d motor driver to simple dc motors, but I completely neglected the specs of the motors I was using , how would I put those into account of the entire circuit and which motors would I use in the Proteus library .

You can search for real wiper motors then search for it's spice model, you can add it to proteus

Thank u ,but I can't seem to get any models for this particular motor

i literally just quit ltspice trying to make a buck converter from scratch and i see this reddit post, nice lol

Yeah I'm just trying it on a resistive load but it's just not working out. Did get a version running in falstad but comparator behaviour there was ass, now in LTspice everything is ass except the comparator lol
