I have an issue in connecting an ideal torque sensor and an ideal rotational sensor to my BLDC motor.
I saw a lot of question and everybody says that the problem is put in parallel this two sensors. But i cannot fully understand the meaning.
Could you please answer with some photo about the differences?
I add a photo of my situation, honestly I cannot see a different way to use this two sensors together.
Thank you in advance

Simscape is multi-domain plant modeling tool, and each domain has its own variables, which defines power.
In the mechanical rotational domain, two variables are angular velocity and torque.
So, you can detect angular velocity or torque from that domain.
You can refer to the detailed info. at :

Hi Leonardo
Torque is a through variable measured with a torque sensor (TS) in series with the shaft of the motor. Speed is an across variable (potential) measured with a rotational sensor (Rot S) in parallel.
In your case, if S is the shaft of the motor, the connection is S - (TS - port R) - (TS - port C) - (Rot S - port R) - mechanical load (inertia, torque source...) (Rot S - port C) connected to a mechanical reference is correct.
Hope this helps out Regards Juan

If the intent is to measure net torque on the hydraulic machine, then the torque sensor should be connected between the machine and the junction point (like how you would connect a hydraulic flow rate sensor).
This was the cause for a* very specific* model. If you cannot resolve your issue by going through the Simscape documentation and you have a valid license with maintenance, then please contact Technical Support.
