Problem with permanent magnet synchronous machine simulink

[andrea-94]

Hi I would ask someone that is pratical with Simulink in particular of Simscape about a problem which involve my simulation in Matlab-Simulink of a permanent magnet synchronous machine that is connected, by a rectifier, to a DC current source.
all the blocks of the simuation are included into the Simulink library.
I try to input a constant torque in the PMSM (which has to be negative sign to use in generator mode) but the simulation doesn't woek and the current of the rectifier is infinite.
thank's everybody I hope someone colud help me.

I'm not familiar with Matlab-Simulink but...

the current of the rectifier is infinite

Are you trying to charge the voltage source/battery? In that case what limits the charging current?

Is this the model?

It says it is 3-phase. Does it have a neutral connection? How have you connected a rectifier?
