for me, your attached inverter schematic did not work at all. the picture was all black.
anyway, you have a pulse transformer? probably not a good thing to use for motor control, because most motor control applications require variable duty cycle, from 0% all the way to 100%. you don't really get that with a pulse transformer.
other options like IRF2100 or whatever are nice (well, very nice) but also expensive. i think $10USD each. heck, that's more than the ENTIRE parts cost than some 100W inverters i have built in the past (not including heatsink & battery supply).
when it comes to gate drives, i think one chip solutions are nice (see texas instrument TD351) if you are building small production line (i.e. less than 1000 units). but for ANYTHING more than that quantity you must really think your strategy. even 1 cent can make a difference when you are building a million units.
for gate drives of any significant power, like more than 1kw, you must pay careful attention to your layout. parasitic capacitance & inductance will KILL you. well, not literally (hopefully) but could make your circuit really crap really fast.
