Questions on motors

[Yi Zhong]

Hi,

I am using a rotational motor to connect the stator and rotor. Unlike what the demo_IRR_motors, my stator is not set as fixed. I am using ChLinkMotorRotationSpeed and set the rotational speed as a constant function. Both my stator and rotor encounter some resistant torque when the motor is on. Based on my understanding, the rotational motor controls the relative rotational speed between stator and rotor. However, my simulation results show that the relative rotational speed does not seem to be constant. Does anyone have an idea what might cause this problem?

Best,

Yi
