60v Dc motor driver with isolator and h-bridge

[emperror123]

dear all
currently i have facing some problem about circuit design

currently i use proteus 8 to run the simulation about it

since my design required function gen or signal gen -> isolator -> h-bridge -> 60V DC motor

i have try simulate DC motor without isolator it work well

simulation of isolator work well too, input 5v output approximated 4.8v

when i connected to my h-bridge, the voltage sudden drop to less than 1V, so how do i solve the issue, i have try many method but still failed, hope you all may let me know what is the solution,

thank you, below are the attachment of schematic and the circuit file for proteus 8

Hi,

I will create and upload to you the isolated H-Bridge Driver to drive the motor hope you like it because i only have porteus 7 and not 8 so i can't open your file

hi,

You have an error in connecting the electric motor in the scheme.

PS. Try this simulation.
