Was wondering if you could help out with this question. I've been trying to solve it for the past two days and I can't seem to solve it. A dc motor develops a torque of 600 Nm when its armature carries a current of 30 Amperes. predict the torque that will be developed when a 12% increase in flux density has taken place and the armature current is increased to 35 amperes. |

In a dc motor torque is proportional to flux X amps. So in your case predicted torque will be 600 X 1.12 X 35/30 or 784 Nm. For a more detailed look at a dc motor model take a look at: https://www.circuitlab.com/editor/#?id=7s2rxdvy2z2k |
