In this video, we design and simulate DC Motor for various load torques. We observe how the armature current and motor speed changes for, full load, no load, half of full load and one fourth of full load.
For a d.c. motor, Torque is directly proportional to the product of Armature current and main flux.
Now is the flux produced by the field winding and is proportional to the current passing through the field winding.
Similarly the back emf produced in the armature is given by,
These relations play an important role in understanding the various characteristics of different types of motors. Design document link : https://bit.ly/34Jvkw9
The design to the following video along with formulae and data required is provided in the document listed above.
Do refer the above video for any clarifications of any kind. If you still have any queries, post them down in the comments sections and we shall get back to you at the earliest.
