DC Motor parameter in simscape

Question

I'm here because I'm trying to implement a DC motor model in simscape. I'm having trouble matching the motor specifications, after filling the block with the parameters taken from the datasheet the output is not what I was expecting. For instance the speed with load is rated at 4310rpm, the output of my model after converting rad/s to rmp is only ~0.6rpm

I'm thinking about some wrong conversion, but can't find the issue by myself. Following the model implementation and motor parameters.

• motor parameters

• motor scheme

• block configuration

• system implementation

• simulation result

Thanks to everyone
