Torque developed by a D.C. motor depends upon_____________?
Correct answer: F. all above factors
- A. magnetic field
- B. active length of the conductor
- C. current flow through the conductors
- D. number of conductors
- E. radius of armature
- F. all above factors
Explanation
Motor torque follows the force on the armature conductors, with T proportional to flux, current, conductor length, number of conductors, and armature radius. Therefore, under the stated factors, all listed quantities affect torque.
