actuate a revolute joint with a dc motor

Hello everyone,

I am new to Matlab simulink and I'm a trying to simulate a whinch for a ROV with simscape multibody. The system is not complex at all, somehow I need help for modeling it.

I have a dc motor that needs to actuate a gear (let's call it driver) to mesh another one (driven). I don't know how to actuate the revolute joint used for the driver with the torque of the dc motor.

Any idea ? Thank you !

Dear Felix

There is a free library managed by MathWorks staff that allow you to connect multibody 3d and Simscape 1d simulation. Basically you need to create a kinematic relationship between joint and 1D motor block from Simscape.

Take a look at this and the various exampe, this will solve your problem:
