Day 2

Day 2 was fairly exciting, we basically had to complete our DC motor kit. It was more of luck than skill, to get everyone just right to the electromagnetic force will spin the shaft. With all the wiring, coiling, recoiling and recoiling, it took a lot of time to get everyone perfect. There was no 'in between' get right or wrong. Eventually, we got to the point where we gave up as it was 'lost hope'. We scrapped the kit. After lunch, while the rest of us were working on our slides, one of us got a professor to help out. He reworked the entire motor, and after much anticipation, we got the motor working

Though we were not the first or the second, we still completed out goal. The motor, although does not spin very fast, we the result of our hard work, and a considerable amount of luck.

Day 1

  We were briefed on our project at the NTU lab, where the electrical equipment is kept. There, we constructed a basic DC motor, using some wires, a strong magnet that could potentially screw up your phone's memory, a think piece of iron rod which is coiled around tightly using the wires and a AA battery. The circuit formed a small electromagnet, which, when put close enough, interacted with the permeant magnet and caused the electromagnet to sway back and forth for a shot while after the circuit was closed.

  Due to the fact that the motor we made was a very basic one, it did not flex that much. After our break, we proceeded to build our next DC motor, This time, a more complex version, which when built properly, will act like a real motor. Comprised out of more than 5m of wire, a partial metal loop, a metal shaft, 2 metal plates and some plastic electrical components, it would create a moving central shaft, just like a real motor. The most important step was to coil the wire around the base of the partial metal loop. This, when connected to a power source, would create a electromagnet.

          » What sounds interesting

Getting to build a working DC electric motor and understand how a conventional motor works, seeing how one of the many devices that we generally take for granted.

          » What do you think you can learn form this project

I can learn how and why a DC motor is built and how it works.
