How to calculate power using Simscape planetary gear block?

We are planning to calculate power by multiplying the torque value obtained from a SimScape planetary gear block with its angular velocity. We have connected a torque sensor and rotational sensor to the carrier output, but the torque value remains at zero. We would like to know how to correctly connect the torque sensor to obtain accurate torque values. Furthermore, if there is a method to calculate power by multiplying torque and rotational speed without using sensors, that would be even better. We are also interested in how to apply this to the Sun and Ring components for power calculations.

(I uploaded this model too.)

Your carrier is fixed to the ground(or chassis) Why would you like to calculate Rotational speed and torque of carrier?

In my humble opinion(and others correct me if I'm wrong) but your sensors seems to be connected right.

As I didn't use simscape for long time so cannot remember exactly, but what is the source sending?

torque value? or speed value?

안녕하세요

구하시고 하는 토크 값은 Simscape 상에서 through variable 이기에 에너지가 토크센서를 관통해서 전달되어야 합니다.Rotational spring을 추가하거나 시스템의 구조를 다시 한번 확인해 보시기 바랍니다. 추가적으로 Power를 측정할 수 있는 블럭을 활용하시면 보다 편리하게 사용할 수 있습니다.

친절한 답변 진심으로 감사드립니다.

추가 궁금한 점이 있어 남깁니다.

1).rotational Power sensor의 경우 S는 ideal torque source에 연결했는데 R과 C의 값 연결이 이상해서 인지 power는 0으로 나와요ㅜ 다시 한번 좋은 답변 진심으로 감사합니다.
