How to compute torque on a brushless with sensor

Ciro Alosa_22608

Hi everyone,

 

how can I compute torque on a brushless motor with a sensor?

 

I'd want to export the model to Simulink and I need the torque. Are there any other possibilities?

Hi,

To compute the torque in Flux using a sensor you need to create a sensor. To do it:

• In parameter/quantity j, create a new sensor
• Type of sensor: predefined, magnetic torque
• Rotation axis:    
  • Direction: parallel to oz
  • Pivot point (0,0)
• Computation domain: select a face region.

Other way to compute the torque is to draw a 2D curve of torque. To do it:

• Curve
• 2D curve (I/O parameter) >> new >> mechanical set >> select electromagnetic torque

To use this data in Simulink, you can export this curve as txt file. In you Simulink model you can use a look up table to read this txt file.

 

Hope this will help.

Best regards.
