How to use PMSM from SimPowerSystems block with Simscape Model

Hello together,

I'm trying modelling of actuator which is powered by PMSM from SimPowerSystems block. I have connected the motor 'S' port with other mechanical input such as gear and spring and ideal torque source but when I vary papameters of spring there is no change in output position or speed. Attached the similar work insted of stepper i wanted to use PMSM block with 'S' port.

How can I connect the PSMS with the mechanical model, so that the robot is I can get accurate readings?

Thank you for your help.

Kind regards,

You need to share your model, not a picture of a working example, if you would like help. It sounds like your model is set up incorrectly if changing the mechanicla model doesn't change the motor behavior. There could be problems with the solver settings, the torque source my be connecting differently, etc. We can't help you without information on what you specifically did in the model that doesn't work.
