Hey !!!
I am new to Ansys Maxwell
I have a question about ansys maxwell
I found that Torque from RMxpart menu is different with the Torque from 2D/3D
The maximum torque from RMxpart is 125 Nm and The maximum torque from 2D/3D design is about 5 Nm
My question is why is the torque from RMxpart is different with the torque from 2D/3D design?

Hello,

In order to simulate the motor on maximum torque, you should implement the additional torque as a load on the rotor (Tload = Tproduced).

In order to obtain more information, please visit : Ansys Electronics 2022 R2 - Using the initial mechanical transient setup by RMxprt ( Maxwell Help > RMxprt Help > Post Processing and Generating Reports in RMxprt > Using the initial mechanical transient setup by RMxprt)

Hi Norrick,

Did you observe the X-axis of both the graphs from Maxwell and Rmxprt?

RMXprt plot is the torques vs. speed graph with a full range of speed values. Whereas Maxwell performs the single-point analysis with the angular velocity set during the motion setup. i.e., 5Nm torque corresponds to the Speed assigned in the motion setup.

If you drew a horizontal line on the RMXprt plot at 5 Nm it should match closely with the corresponding speed that you set on the Maxwell setup.
