I got not logic current from motor which value from numbers suddenly 0 value. I think I have problem with the connection but still cannot find the mistake

Above, This is my model simulink

this my current from motor .

I think i having wrong connection from Dc motor,H-bridge,controlled pwm voltage

The model is mixing two different technologies, Simscape and Specialized Power Systems. In R2024b release it is not even possible to simulate the model because there is a loop of voltage sources in the Specialized Power systems part. Would be best to use a single technology and start building the model system by system and then integrating systems together.

Simscape part is also not well modelled as the model is not giving enough information to make it possible to solve for values of some variables, particularly voltages in the H-bridge. Also the Controlled PWM Voltage ref- terminal is not connected to anything. A good starting point in learning more about modeling and simulation of EVs is this example:
