DC motor model

[DHXL]

I wanted to create DC motor drive simulation, but then realised that motor doesn't work as I expected.
Can someone clarify how to read motor values?

I expected that when you switch on the circuit, motor current rises to its maximum (considering inductance in the circuit), the motor starts to spin and its current lowers, because its back EMF rises. While I see some settings related to back EMF (then it means that this exists) and change in back EMF constant makes motor behaviour different, I don't understand why the current is rising the faster the engine rotates.

basically you are seeing the delay as the inductor gets up to full magnetism - the time step is much slower than real time
see this wiki page to explain some of the terms https://en.wikipedia.org/wiki/Motor_constants.

It is a shame that there is not yet an option for motors that have actual separate windings (to play with series/shunt and compound windings) as from what I have read, current flow is far more interesting

The behavior described is the expected motor startup transient — current rises through the armature inductance before back-EMF from the spinning rotor builds up to limit it. The time axis in the simulator may run slower than real-time depending on circuit complexity and timestep settings.
