Absolutely great video, thanks a lot. A small note for everyone: Something missed in the video, the armature coils don't exert only back EMF, they exert magnetic field opposite to beneficial flux also. Because of this, at the big powered machines; some extra coils which called "commutation coils" and "compensation coils" being used to get rid of the armature flux.

Basically, The current-carrying conductor produces its own magnetic field which interacts with the external magnetic field of the permanent magnet. This interaction is what moves the wire. If we make the conductor into a squarish U-shaped loop and fit a power source. Then one arm of the conductor will have the current coming towards the power source and the other one going out in the presence of the external magnetic field provided by the permanent magnets. Therefore, one half of the conductor will move upwards and the other half will move downwards and we would assume that the conductor will carry on rotating like this and we would be on our way of having DC motor. Two major problem occurs with this design. One is that the wires will tangle up and another one is that once the coil reaches the vertical position after rotating far enough, it would flip over, so the electric current would be flowing in the opposite direction. Now the forces on each side of the coil would reverse. Instead of rotating continuously in the same direction, it would move back in the direction it had just come. We need to periodically reverse the direction of the current to overcome this problem. So a commutator is used to overcome this problem. In the simplest form, the commutator is a metal ring divided into two separate halves and its job is to reverse the current direction every time the coil makes half a turn. Now since the torque becomes very small when the coil is perpendicular to the magnetic flux, the motion will be very irregular. To overcome this problem, one more loop of coil is added with a separate commutator ring (when the first loop is in the vertical position, the second loop is connected to the power source and therefore a motive force will always be present). To make the rotor motion even smoother, more loops and corresponding commutator rings are added. Next, the magnetic flux interaction is enhanced by fitting the armature loops inside the slots of highly permeable steel layers. And spring loaded commutator brushes help to make contact with the power source. In a practical motor, the permanent magnets are curved in a circular shape so it almost touches the coil of wire that rotates inside it. The closer together the magnet and the coil, the greater the force the motor can produce. DC motors are used for small applications like toys but you won't find them in house-hold appliances. For them, universal motors are used. In universal motors, instead of stator being permanent magnets, electromagnets are used and therefore, can be powered by DC and as well as AC.

In the beginning of the video you mention stator, but no label or arrow pointing to it. In the future, as you introduce each component, show a label for it with an arrow to designate it, so no assumption has to be made as to which component it's referencing.

Very useful and thanks for uploading it. Couldn't understand it from my textbook. 1 doubt btw. According to Fleming's left hand rule, the North Pole will apply force towards the south Pole, and the current, the magnetic field, and the motion are perpendicular to each other. So, the North Pole should apply force on the coil which is connected to the split rings. The motion should be opposite I guess.

Hi! Great video, just like all your other ones! I have a question about the armature of the rotor. You say that it has HIGH permeability to ease the magnetic flux interaction. Shouldn´t it be with LOW permeability so it will reduce the eddy current losses when the rotor turns inside the magnetic field of the poles? Hope i was clear with the question. Thanks.
@AdityaRaj-kc4nv
@AdityaRaj-kc4nv 2 жыл бұрын
High permeability is required to properly interact with magnetic field of stator. And as for eddy current losses, the armature metal is laminated to reduce eddy losses. ( I know it's late but ok)
