Simscape Torque Sensor output is zero

Question

0 个投票

I'm simulating the simscape PMSM.

I set a fixed angular velocity via a Ideal Angular Velocity Source.

I want to measure angle via an Ideal Rotational Motion Sensor and torque via an Ideal Torque Sensor. I cannot find a configuration of the three blocks that will lead to a converging simuation and a measured torque that is not zero (despite phase currents flowing).

Here is my set up: (the ports R C are connected to the PMSM RC ports)

I read other threads on the issue of torque and roatinal sensing but no configuration of the two sensors lead to valid measurements and a converging simulation

Do you have suggestions on how to connect the sensors and source?

Many thanks!
