SUMMARY

External torque and torque are distinct concepts in motor control. Torque refers to the electromagnetic torque developed by an electric machine, while external torque is the torque imposed by external loads, such as generators (positive) and fans or compressors (negative). Understanding these differences is crucial for accurate motor control and system design. A free body diagram can effectively illustrate the relationship between these forces and their respective torques.

PREREQUISITES
  • Understanding of electromagnetic torque in electric machines
  • Familiarity with load types, including generators and compressors
  • Basic knowledge of free body diagrams
  • Concept of torque in mechanical systems
NEXT STEPS
  • Study the principles of electromagnetic torque in electric machines
  • Research the effects of external loads on motor performance
  • Learn how to create and interpret free body diagrams
  • Explore the dynamics of torque in mechanical systems
USEFUL FOR

Motor control engineers, electrical engineers, and anyone involved in the design and analysis of electric machines and their loads.

is there any difference between external torque and torque?
 
Physics news on Phys.org
Motor control engineer here (so my answer is not really physics-based):

Torque - EM torque developed by an electric machine
External torque - torque imposed by load (positive - generators such as gas/wind, negative - fans, compressors, etc.)
 
Draw a free body diagram. If the force producing the torque is external to a circle drawn around the body, the the force and its torque are external.
