hello. this (see first photo) is an h-bridge project on proteus. will be simulating it as well on ltspice/multisim but i cant seem to find the dc motor component. is this (2nd photo) the alternative dc motor model for it? kindly dont mind the values.
im still learning the software so any help is very much appreciated!^^
A DC motor has a high current when it starts and is stalled but its running current is much less. Use ohm's Law to calculate its stalled resistance and use it in your simulation.
I'd expect a more reasonable "model" of a DC motor to be a low value resistor in series with an inductor.
A stalled or zero speed motor is pretty much just an electromagnet or coil; resistance and inductance.

And add a voltage source in series for the back emf at non-zero speeds, as ST says.
